JEAN LOUIS RODOLPHE AGASSIZ was born May 28, 1807, at the village

of Motier, on the Lake of Morat. His father, Louis Rodolphe

Agassiz, was a clergyman; his mother, Rose Mayor, was the daughter

of a physician whose home was at Cudrefin, on the shore of the Lake

of Neuchatel.

The parsonages in Switzerland are frequently pretty and

picturesque. That of Motier, looking upon the lake and sheltered by

a hill which commands a view over the whole chain of the Bernese

Alps, was especially so. It possessed a vineyard large enough to

add something in good years to the small salary of the pastor; an

orchard containing, among other trees, an apricot famed the country

around for the unblemished beauty of its abundant fruit; a good

vegetable garden, and a delicious spring of water flowing always

fresh and pure into a great stone basin behind the house. That

stone basin was Agassiz's first aquarium; there he had his first

collection of fishes.* (* After his death a touching tribute was

paid to his memory by the inhabitants of his birthplace. With

appropriate ceremonies, a marble slab was placed above the door of

the parsonage of Motier, with this inscription, "J. Louis Agassiz,

celebre naturaliste, est ne dans cette maison, le 28 Mai, 1807.")

It does not appear that he had any precocious predilection for

study, and his parents, who for the first ten years of his life

were his only teachers, were too wise to stimulate his mind beyond

the ordinary attainments of his age. having lost her first four

children in infancy, his mother watched with trembling solicitude

over his early years. It was perhaps for this reason that she was

drawn so closely to her boy, and understood that his love of

nature, and especially of all living things, was an intellectual

tendency, and not simply a child's disposition to find friends and

playmates in the animals about him. In later years her sympathy

gave her the key to the work of his manhood, as it had done to the

sports of his childhood. She remained his most intimate friend to

the last hour of her life, and he survived her but six years.

Louis's love of natural history showed itself almost from infancy.

When a very little fellow he had, beside his collection of fishes,

all sorts of pets: birds, field-mice, hares, rabbits, guinea-pigs,

etc., whose families he reared with the greatest care. Guided by

his knowledge of the haunts and habits of fishes, he and his

brother Auguste became the most adroit of young fishermen,--using

processes all their own and quite independent of hook, line, or

net. Their hunting grounds were the holes and crevices beneath the

stones or in the water-washed walls of the lake shore. No such

shelter was safe from their curious fingers, and they acquired such

dexterity that when bathing they could seize the fish even in the

open water, attracting them by little arts to which the fish

submitted as to a kind of fascination. Such amusements are no doubt

the delight of many a lad living in the country, nor would they be

worth recording except as illustrating the unity of Agassiz's

intellectual development from beginning to end. His pet animals

suggested questions, to answer which was the task of his life; and

his intimate study of the fresh-water fishes of Europe, later the

subject of one of his important works, began with his first

collection from the Lake of Morat.

As a boy he amused himself also with all kinds of handicrafts on a

small scale. The carpenter, the cobbler, the tailor, were then as

much developed in him as the naturalist. In Swiss villages it was

the habit in those days for the trades-people to go from house to

house in their different vocations. The shoemaker came two or three

times a year with all his materials, and made shoes for the whole

family by the day; the tailor came to fit them for garments which

he made in the house; the cooper arrived before the vintage, to

repair old barrels and hogsheads or to make new ones, and to

replace their worn-out hoops; in short, to fit up the cellar for

the coming season. Agassiz seems to have profited by these lessons

as much as by those he learned from his father; and when a very

little fellow, he could cut and put together a well-fitting pair of

shoes for his sisters' dolls, was no bad tailor, and could make a

miniature barrel that was perfectly water-tight. He remembered

these trivial facts as a valuable part of his incidental education.

He said he owed much of his dexterity in manipulation, to the

training of eye and hand gained in these childish plays.

Though fond of quiet, in-door occupation, he was an active, daring

boy. One winter day when about seven years of age, he was skating

with his little brother Auguste, two years younger than himself,

and a number of other boys, near the shore of the lake. They were

talking of a great fair held that day at the town of Morat, on the

opposite side of the lake, to which M. Agassiz had gone in the

morning, not crossing upon the ice, however, but driving around the

shore. The temptation was too strong for Louis, and he proposed to

Auguste that they should skate across, join their father at the

fair, and come home with him in the afternoon. They started

accordingly. The other boys remained on their skating ground till

twelve o'clock, the usual dinner hour, when they returned to the

village. Mme. Agassiz was watching for her boys, thinking them

rather late, and on inquiring for them among the troop of urchins

coming down the village street she learned on what errand they had

gone. Her anxiety may be imagined. The lake was not less than two

miles across, and she was by no means sure that the ice was safe.

She hurried to an upper window with a spy-glass to see if she could

descry them anywhere. At the moment she caught sight of them,

already far on their journey, Louis had laid himself down across a

fissure in the ice, thus making a bridge for his little brother,

who was creeping over his back. Their mother directed a workman, an

excellent skater, to follow them as swiftly as possible. He

overtook them just as they had gained the shore, but it did not

occur to him that they could return otherwise than they had come,

and he skated back with them across the lake. Weary, hungry, and

disappointed, the boys reached the house without having seen the

fair or enjoyed the drive home with their father in the afternoon.

When he was ten years old, Agassiz was sent to the college for boys

at Bienne, thus exchanging the easy rule of domestic instruction

for the more serious studies of a public school. He found himself

on a level with his class, however, for his father was an admirable

teacher. Indeed it would seem that Agassiz's own passion for

teaching, as well as his love of young people and his sympathy with

intellectual aspiration everywhere, was an inheritance. Wherever

his father was settled as pastor, at Motier, at Orbe, and later at

Concise, his influence was felt in the schools as much as in the

pulpit. A piece of silver remains, a much prized heir-loom in the

family, given to him by the municipality of Orbe in acknowledgment

of his services in the schools.

The rules of the school at Bienne were rather strict, but the life

led by the boys was hardy and invigorating, and they played as

heartily as they worked. Remembering his own school-life, Agassiz

often asked himself whether it was difference of climate or of

method, which makes the public school life in the United States so

much more trying to the health of children than the one under which

he was brought up. The boys and girls in our public schools are

said to be overworked with a session of five hours, and an

additional hour or two of study at home. At the College of Bienne

there were nine hours of study, and the boys were healthy and

happy. Perhaps the secret might be found in the frequent

interruption, two or three hours of study alternating with an

interval for play or rest. Agassiz always retained a pleasant

impression of the school and its teachers. Mr. Rickly, the

director, he regarded with an affectionate respect, which ripened

into friendship in maturer years.

The vacations were, of course, hailed with delight, and as Motier

was but twenty miles distant from Bienne, Agassiz and his younger

brother Auguste, who joined him at school a year later, were in the

habit of making the journey on foot. The lives of these brothers

were so closely interwoven in their youth that for many years the

story of one includes the story of the other. They had everything

in common, and with their little savings they used to buy books,

chosen by Louis, the foundation, as it proved, of his future

library.

Long before dawn on the first day of vacation the two bright,

active boys would be on their homeward way, as happy as holiday

could make them, especially if they were returning for the summer

harvest or the autumn vintage. The latter was then, as now, a

season of festivity. In these more modern days something of its

primitive picturesqueness may have been lost; but when Agassiz was

a boy, all the ordinary occupations were given up for this

important annual business, in which work and play were so happily

combined. On the appointed day the working people might be seen

trooping in from neighboring cantons, where there were no

vineyards, to offer themselves for the vintage. They either camped

out at night, sleeping in the open air, or found shelter in the

stables and outhouses. During the grape gathering the floor of the

barn and shed at the parsonage of Motier was often covered in the

evening with tired laborers, both men and women. Of course, when

the weather was fine, these were festival days for the children. A

bushel basket, heaped high with white and amber bunches, stood in

the hall, or in the living room of the family, and young and old

were free to help themselves as they came and went. Then there were

the frolics in the vineyard, the sweet cup of must (unfermented

juice of the grape), and, the ball on the last evening at the close

of the merry-making.

Sometimes the boys passed their vacations at Cudrefin, with their

grandfather Mayor. He was a kind old man, much respected in his

profession, and greatly beloved for his benevolence. His little

white horse was well known in all the paths and by-roads of the

country around, as he went from village to village among the sick.

The grandmother was frail in health, but a great favorite among the

children, for whom she had an endless fund of stories, songs, and

hymns. Aunt Lisette, an unmarried daughter, who long lived to

maintain the hospitality of the old Cudrefin house and to be

beloved as the kindest of maiden aunts by two or three generations

of nephews and nieces, was the domestic providence of these family

gatherings, where the praises of her excellent dishes were annually

sung. The roof was elastic; there was no question about numbers,

for all came who could; the more, the merrier, with no diminution

of good cheer.

The Sunday after Easter was the great popular fete. Then every

house was busy coloring Easter eggs and making fritters. The young

girls and the lads of the village, the former in their prettiest

dresses and the latter with enormous bouquets of artificial flowers

in their hats, went together to church in the morning. In the

afternoon the traditional match between two runners, chosen from

the village youths, took place. They were dressed in white, and

adorned with bright ribbons. With music before them, and followed

by all the young people, they went in procession to the place where

a quantity of Easter eggs had been distributed upon the ground. At

a signal the runners separated, the one to pick up the eggs

according to a prescribed course, the other to run to the next

village and back again. The victory was to the one who accomplished

his task first, and he was proclaimed king of the feast. Hand in

hand the runners, followed as before by all their companions,

returned to join in the dance now to take place before the house of

Dr. Mayor. After a time the festivities were interrupted by a

little address in patois from the first musician, who concluded by

announcing from his platform a special dance in honor of the family

of Dr. Mayor. In this dance the family with some of their friends

and neighbors took part,--the young ladies dancing with the peasant

lads and the young gentlemen with the girls of the village,--while

the rest formed a circle to look on.

Thus, between study and recreation, the four years which Agassiz's

father and mother intended he should pass at Bienne drew to a

close. A yellow, time-worn sheet of foolscap, on which during the

last year of his school-life he wrote his desiderata in the way of

books, tells something of his progress and his aspirations at

fourteen years of age. "I wish," so it runs, "to advance in the

sciences, and for that I need d'Anville, Ritter, an Italian

dictionary, a Strabo in Greek, Mannert and Thiersch; and also the

works of Malte-Brun and Seyfert. I have resolved, as far as I am

allowed to do so, to become a man of letters, and at present I can

go no further: 1st, in ancient geography, for I already know all my

notebooks, and I have only such books as Mr. Rickly can lend me; I

must have d'Anville or Mannert; 2nd, in modern geography, also, I

have only such books as Mr. Rickly can lend me, and the Osterwald

geography, which does not accord with the new divisions; I must

have Ritter or Malte-Brun; 3rd, for Greek I need a new grammar, and

I shall choose Thiersch; 4th, I have no Italian dictionary, except

one lent me by Mr. Moltz; I must have one; 5th, for Latin I need a

larger grammar than the one I have, and I should like Seyfert; 6th,

Mr. Rickly tells me that as I have a taste for geography he will

give me a lesson in Greek (gratis), in which we would translate

Strabo, provided I can find one. For all this I ought to have about

twelve louis. I should like to stay at Bienne till the month of

July, and afterward serve my apprenticeship in commerce at

Neuchatel for a year and a half. Then I should like to pass four

years at a university in Germany, and finally finish my studies at

Paris, where I would stay about five years. Then, at the age of

twenty-five, I could begin to write."

Agassiz's note-books, preserved by his parents, who followed the

education of their children with the deepest interest, give

evidence of his faithful work both at school and college. They form

a great pile of manuscript, from the paper copy-books of the

school-boy to the carefully collated reports of the college

student, begun when the writer was ten or eleven years of age and

continued with little interruption till he was eighteen or

nineteen. The later volumes are of nearly quarto size and very

thick, some of them containing from four to six hundred closely

covered pages; the handwriting is small, no doubt for economy of

space, but very clear. The subjects are physiological,

pathological, and anatomical, with more or less of general natural

history. This series of books is kept with remarkable neatness.

Even in the boy's copy-books, containing exercises in Greek, Latin,

French and German, with compositions on a variety of topics, the

writing is even and distinct, with scarcely a blot or an erasure.

From the very beginning there is a careful division of subjects

under clearly marked headings, showing even then a tendency toward

an orderly classification of facts and thoughts.

It is evident from the boyish sketch which he drew of his future

plans that the hope of escaping the commercial life projected for

him, and of dedicating himself to letters and learning, was already

dawning. He had begun to feel the charm of study, and his

scientific tastes, though still pursued rather as the pastimes of a

boy than as the investigations of a student, were nevertheless

becoming more and more absorbing. He was fifteen years old and the

time had come when, according to a purpose long decided upon, he

was to leave school and enter the business house of his uncle,

Francois Mayor, at Neuchatel. He begged for a farther delay, to be

spent in two additional years of study at the College of Lausanne.

He was supported in his request by several of his teachers, and

especially by Mr. Rickly, who urged his parents to encourage the

remarkable intelligence and zeal already shown by their son in his

studies. They were not difficult to persuade; indeed, only want of

means, never want of will, limited the educational advantages they

gave to their children.

It was decided, therefore, that he should go to Lausanne. Here his

love for everything bearing on the study of nature was confirmed.

Professor Chavannes, Director of the Cantonal Museum, in whom he

found not only an interesting teacher, but a friend who sympathized

with his favorite tastes, possessed the only collection of Natural

History in the Canton de Vaud. To this Agassiz now had access. His

uncle, Dr. Mathias Mayor, his mother's brother and a physician of

note in Lausanne, whose opinion had great weight with M. and Mme.

Agassiz, was also attracted by the boy's intelligent interest in

anatomy and kindred subjects. He advised that his nephew should be

allowed to study medicine, and at the close of Agassiz's college

course at Lausanne the commercial plan was finally abandoned, and

he was permitted to choose the medical profession as the one most

akin to his inclination.

Being now seventeen years of age, he went to the medical school of

Zurich. Here, for the first time, he came into contact with men

whose instruction derived freshness and vigor from their original

researches. He was especially indebted to Professor Schinz, a man

of learning and ability, who held the chair of Natural History and

Physiology, and who showed the warmest interest in his pupil's

progress. He gave Agassiz a key to his private library, as well as

to his collection of birds. This liberality was invaluable to one

whose poverty made books an unattainable luxury. Many an hour did

the young student pass at that time in copying books which were

beyond his means, though some of them did not cost more than a

dollar a volume. His brother Auguste, still his constant companion,

shared this task, a pure labor of love with him, for the books were

more necessary to Louis's studies than to his own.

During the two years passed by Agassiz in Zurich he saw little of

society beyond the walls of the university. His brother and he had

a pleasant home in a private house, where they shared the family

life of their host and hostess. In company with them, Agassiz made

his first excursion of any importance into the Alps. They ascended

the Righi and passed the night there. At about sunset a fearful

thunder-storm gathered below them, while on the summit of the

mountain the weather remained perfectly clear and calm. Under a

blue sky they watched the lightning, and listened to the thunder in

the dark clouds, which were pouring torrents of rain upon the plain

and the Lake of Lucerne. The storm lasted long after night had

closed in, and Agassiz lingered when all his companions had retired

to rest, till at last the clouds drifted softly away, letting down

the light of moon and stars on the lake and landscape. He used to

say that in his subsequent Alpine excursions he had rarely

witnessed a scene of greater beauty.

Such of his letters from Zurich as have been preserved have only a

home interest. In one of them, however, he alludes to a curious

circumstance, which might have changed the tenor of his life. He

and his brother were returning on foot, for the vacation, from

Zurich to their home which was now in Orbe, where their father and

mother had been settled since 1821. Between Neuchatel and Orbe they

were overtaken by a traveling carriage. A gentleman who was its

sole occupant invited them to get in, made them welcome to his

lunch, talked to them of their student life, and their future

plans, and drove them to the parsonage, where he introduced himself

to their parents. Some days afterward M. Agassiz received a letter

from this chance acquaintance, who proved to be a man in affluent

circumstances, of good social position, living at the time in

Geneva. He wrote to M. Agassiz that he had been singularly

attracted by his elder son, Louis, and that he wished to adopt him,

assuming henceforth all the responsibility of his education and his

establishment in life. This proposition fell like a bomb-shell into

the quiet parsonage. M. Agassiz was poor, and every advantage for

his children was gained with painful self-sacrifice on the part of

both parents. How then refuse such an opportunity for one among

them, and that one so gifted? After anxious reflection, however,

the father, with the full concurrence of his son, decided to

decline an offer which, brilliant as it seemed, involved a

separation and might lead to a false position. A correspondence was

kept up for years between Louis and the friend he had so suddenly

won, and who continued to interest himself in his career. Although

it had no sequel, this incident is mentioned as showing a kind of

personal magnetism which, even as child and boy, Agassiz

unconsciously exercised over others.

From Zurich, Agassiz went to the University of Heidelberg, where we

find him in the spring of 1826.

TO HIS FATHER.

HEIDELBERG, April 24, 1826.

. . .Having arrived early enough to see something of the environs

before the opening of the term, I decided to devote each day to a

ramble in one direction or another, in order to become familiar

with my surroundings. I am the more glad to have done this as I

have learned that after the lectures begin there will be no further

chance for such interruptions, and we shall be obliged to stick

closely to our work at home.

Our first excursion was to Neckarsteinach, two and a half leagues

from here. The road follows the Neckar, and at certain places rises

boldly above the river, which flows between two hills, broken by

rocks of the color of red chalk, which often jut out from either

side. Farther on the valley widens, and a pretty rising ground,

crowned by ruins, suddenly presents itself in the midst of a wide

plain, where sheep are feeding. Neckarsteinach itself is only a

little village, containing, however, three castles, two of which

are in ruins. The third is still inhabited, and commands a

magnificent view. In the evening we returned to Heidelberg by

moonlight.

Another day we started for what is here called "The Mountain,"

though it is at most no higher than Le Suchet. As the needful

supplies are not to be obtained there, we took our provisions with

us. We had so much fun out of this, that I must tell you all about

it. In the morning Z--bought at the market veal, liver, and bacon

enough to serve for three persons during two days. To these

supplies we added salt, pepper, butter, onions, bread, and some

jugs of beer. One of us took two saucepans for cooking, and some

alcohol. Arrived at the summit of our mountain, we looked out for a

convenient spot, and there we cooked our dinner. It did not take

long, nor can I say whether all was done according to the rules of

art. But this I know,--that never did a meal seem to me better. We

wandered over the mountain for the rest of the day, and at evening

came to a house where we prepared our supper after the same

fashion, to the great astonishment of the assembled household, and

especially of an old woman who regretted the death of her husband,

because she said it would certainly have amused him. We slept on

the ground on some straw, and returned to Heidelberg the next day

in time for dinner. The following day we went to Mannheim to visit

the theatre. It is very handsome and well appointed, and we were

fortunate in happening upon an excellent opera. Beyond this, I saw

nothing of Mannheim except the house of Kotzebue and the place

where Sand was beheaded.

To-day I have made my visits to the professors. For three among

them I had letters from Professors Schinz and Hirzel. I was

received by all in the kindest way. Professor Tiedemann, the

Chancellor, is a man about the age of papa and young for his years.

He is so well-known that I need not undertake his panegyric here.

As soon as I told him that I brought a letter from Zurich, he

showed me the greatest politeness, offered me books from his

library; in one word, said he would be for me here what Professor

Schinz, with whom he had formerly studied, had been for me in

Zurich. After the opening of the term, when I know these gentlemen

better, I will tell you more about them. I have still to describe

my home, chamber, garden, people of the house, etc.

The next letter fills in this frame-work.

TO HIS FATHER.

HEIDELBERG, May 24, 1826.

. . .According to your request, I am going to write you all

possible details about my host, the employment of my time, etc.,

etc. Mr.--, my "philister," is a tobacco merchant in easy

circumstances, having a pretty house in the faubourg of the city.

My windows overlook the town, and my prospect is bounded by a hill

situated to the north of Heidelberg. At the back of the house is a

large and fine garden, at the foot of which is a very pretty

summer-house. There are also several clumps of trees in the garden,

and an aviary filled with native birds. . .

Since each day in term time is only the repetition of every other,

the account of one will give an idea of all, especially as I follow

with regularity the plan of study I have formed. Every morning I

rise at six o'clock, dress, and breakfast. At seven I go to my

lectures, given during the morning in the Museum building, next to

which is the anatomical laboratory. If, in the interval, I have a

free hour, as sometimes happens from ten to eleven, I occupy it in

making anatomical preparations. I shall tell you more of that and

of the Museum another time. From twelve to one I practice fencing.

We dine at about one o'clock, after which I walk till two, when I

return to the house and to my studies till five o'clock. From five

to six we have a lecture from the renowned Tiedemann. After that, I

either take a bath in the Neckar or another walk. From eight to

nine I resume my special work, and then, according to my

inclination, go to the Swiss club, or, if I am tired, to bed. I

have my evening service and talk silently with you, believing that

at that hour you also do not forget your Louis, who thinks always

of you. . .As soon as I know, for I cannot yet make an exact

estimate, I will write you as nearly as possible what my expenses

are likely to be. Sometimes there may be unlooked-for expenditures,

as, for instance, six crowns for a matriculation paper. But be

assured that at all events I shall restrict myself to what is

absolutely necessary, and do my best to economize. The same of the

probable duration of my stay in Heidelberg; I shall certainly not

prolong it needlessly. . .

Now for the first time the paths of the two brothers separated,

Auguste returning from Zurich to Neuchatel, where he entered into

business. It chanced, however, that in one of the first

acquaintances made by Louis in Heidelberg he found not only a

congenial comrade, but a friend for life, and in after years a

brother. Professor Tiedemann, by whom Agassiz had been so kindly

received, recommended him to seek the acquaintance of young

Alexander Braun, an ardent student, and an especial lover of

botany. At Tiedemann's lecture the next day Agassiz's attention was

attracted by a young man who sat next him, and who was taking very

careful notes and illustrating them. There was something very

winning in his calm, gentle face, full of benevolence and

intelligence. Convinced by his manner of listening to the lecture

and transcribing it that this was the student of whom Tiedemann had

spoken, Agassiz turned to his neighbor as they both rose at the

close of the hour, and said, "Are you Alex Braun?" "Yes, and you,

Louis Agassiz?" It seems that Professor Tiedemann, who must have

had a quick eye for affinities in the moral as well as in the

physical world, had said to Braun also, that he advised him to make

the acquaintance of a young Swiss naturalist who had just come, and

who seemed full of enthusiasm for his work. The two young men left

the lecture-room together, and from that time their studies, their

excursions, their amusements, were undertaken and pursued in each

other's company. In their long rambles, while they collected

specimens in their different departments of Natural History, Braun

learned zoology from Agassiz, and he, in his turn, learned botany

from Braun. This was, perhaps, the reason why Alexander Braun,

afterward Director of the Botanical Gardens in Berlin, knew more of

zoology than other botanists, while Agassiz himself combined an

extensive knowledge of botany with his study of the animal kingdom.

That the attraction was mutual may be seen by the following extract

from a letter of Alexander Braun to his father.

BRAUN To HIS FATHER.

HEIDELBERG, May 12, 1826.

. . .In my leisure hours, between the forenoon and afternoon

lectures, I go to the dissecting-room, where, in company with

another young naturalist who has appeared like a rare comet on the

Heidelberg horizon, I dissect all manner of beasts, such as dogs,

cats, birds, fishes, and even smaller fry, snails, butterflies,

caterpillars, worms, and the like. Beside this, we always have from

Tiedemann the very best books for reference and comparison, for he

has a fine library, especially rich in anatomical works, and is

particularly friendly and obliging to us.

In the afternoon from two to three I attend Geiger's lectures on

pharmaceutical chemistry, and from five to six those of Tiedemann

on comparative anatomy. In the interval, I sometimes go with this

naturalist, so recently arrived among us (his name is Agassiz, and

he is from Orbe), on a hunt after animals and plants. Not only do

we collect and learn to observe all manner of things, but we have

also an opportunity of exchanging our views on scientific matters

in general. I learn a great deal from him, for he is much more at

home in zoology than I am. He is familiar with almost all the known

mammalia, recognizes the birds from far off by their song, and can

give a name to every fish in the water. In the morning we often

stroll together through the fish market, where he explains to me

all the different species. He is going to teach me how to stuff

fishes, and then we intend to make a collection of all the native

kinds. Many other useful things he knows; speaks German and French

equally well, English and Italian fairly, so that I have already

appointed him to be my interpreter on some future vacation trip to

Italy. He is well acquainted with ancient languages also, and

studies medicine besides. . .

A few lines from Braun to his mother, several weeks later, show

that this first enthusiasm, poured out with half-laughing

extravagance to his father, was ripening into friendship of a more

serious character.

BRAUN TO HIS MOTHER.

HEIDELBERG, June 1, 1826.

. . .I am very happy now that I have found some one whose

occupations are the same as mine. Before Agassiz came I was obliged

to make my excursions almost always alone, and to study in

hermit-like isolation. After all, two people working together can

accomplish far more than either one can do alone. In order, for

instance, to utilize the interval spent in the time-consuming and

mechanical work of preparing specimens, pinning insects and the

like, we have agreed that while one is so employed the other shall

read aloud. In this way we shall go through various works on

physiology, anatomy, and zoology.

Next to Alexander Braun, Agassiz's most congenial companion at

Heidelberg was Karl Schimper, a friend of Braun, and like him a

young botanist of brilliant promise. The three soon became

inseparable. Agassiz had many friends and companions at the

university beside those who, on account of their influence upon his

after life, are mentioned here. He was too affectionate not to be a

genial companion among his young countrymen of whom there were many

at Heidelberg, where they had a club and a gymnasium of their own.

In the latter, Agassiz bore his part in all the athletic sports,

being distinguished both as a powerful gymnast and an expert

fencer.

Of the professors then at Heidelberg, Leuckart, the zoologist, was,

perhaps, the most inspiriting. His lectures were full of original

suggestions and clever hypotheses, which excited and sometimes

amused his listeners. He knew how to take advantage of the

enthusiasm of his brighter pupils, and, at their request, gave them

a separate course of instruction on special groups of animals; not

without some personal sacrifice, for these extra lectures were

given at seven o'clock in the morning, and the students were often

obliged to pull their professor out of bed for the purpose. The

fact that they did so shows at least the friendly relation existing

between teacher and scholars. With Bischoff the botanist also, the

young friends were admitted to the most kindly intercourse. Many a

pleasant botanical excursion they had with him, and they owed to

him a thorough and skillful instruction in the use of the

microscope, handled by him like a master. Tiedemann's lectures were

very learned, and Agassiz always spoke of his old teacher in

comparative anatomy and physiology with affectionate respect and

admiration. He was not, however, an inspiring teacher, and though

an excellent friend to the students, they had no such intimate

personal relations with him as with Leuckart and Bischoff. From

Bronn, the paleontologist, they received an immense amount of

special information, but his instruction was minute in details

rather than suggestive in ideas; and they were glad when their

professor, finding that the course must be shortened for want of

time, displayed to them his magnificent collection of fossils, and

with the help of the specimens, developed his subject in a more

general and practical way.* (* This collection was purchased in

1859 by the Museum of Comparative Zoology in Cambridge,

Massachusetts, and Agassiz had thus the pleasure of teaching his

American pupils from the very collection in which he had himself

made his first important paleontological studies.) Of the medical

professors, Nageli was the more interesting, though the reputation

of Chelius brought him a larger audience. If there was however any

lack of stimulus in the lecture rooms, the young friends made good

the deficiency by their own indefatigable and intelligent study of

nature, seeking to satisfy their craving for knowledge by every

means within their reach.* (* The material for this account of the

student life of the two friends at Heidelberg and of their teachers

was chiefly furnished by Alexander Braun himself at the close of

his own life, after the death of Agassiz. The later sketches of the

Professors at Munich in 1832 were drawn in great part from the same

source.)

As the distance and expense made it impossible for Agassiz to spend

his vacations with his family in Switzerland, it soon became the

habit for him to pass the holidays with his new friend at

Carlsruhe. For a young man of his tastes and acquirements a more

charming home-life than the one to which he was here introduced can

hardly be imagined. The whole atmosphere was in harmony with the

pursuits of the students. The house was simple in its appointments,

but rich in books, music, and in all things stimulating to the

thought and imagination. It stood near one of the city gates which

opened into an extensive oak forest, in itself an admirable

collecting ground for the naturalist. At the back certain rooms,

sheltered by the spacious garden from the noise of the street, were

devoted to science. In the first of these rooms the father's rich

collection of minerals was arranged, and beyond this were the

laboratories of his sons and their friends, where specimens of all

sorts, dried and living plants, microscopes and books of reference,

covered the working tables. Here they brought their treasures; here

they drew, studied, dissected, arranged their specimens; here they

discussed the theories, with which their young brains were teeming,

about the growth, structure, and relations of animals and plants.*

(* See "Biographical Memoir of Louis Agassiz" by Arnold Guyuot, in

the "Proceedings of U.S. National Academy".)

From this house, which became a second home to Agassiz, he wrote to

his father in the Christmas holidays of 1826:. . ."My happiness

would be perfect were it not for the painful thought which pursues

me everywhere, that I live on your privations; yet it is impossible

for me to diminish my expenses farther. You would lift a great

weight from my heart if you could relieve yourself of this burden

by an arrangement with my uncle at Neuchatel. I am confident that

when I have finished my studies I could easily make enough to repay

him. At all events, I know that you cannot pay the whole at once,

and therefore in telling me frankly what are our resources for this

object you would do me the greatest favor. Until I know that, I

cannot be at peace. Otherwise, I am well, going on as usual, always

working as hard as I can, and I believe all the professors whose

lectures I attend are satisfied with me.". . .His father was also

pleased with his conduct and with his progress, for about this time

he writes to a friend, "We have the best possible news of Louis.

Courageous, industrious, and discreet, he pursues honorably and

vigorously his aim, namely, the degree of Doctor of Medicine and

Surgery."

In the spring of 1827 Agassiz fell ill of a typhus fever prevalent

at the university as an epidemic. His life was in danger for many

days. As soon as he could be moved, Braun took him to Carlsruhe,

where his convalescence was carefully watched over by his friend's

mother. Being still delicate he was advised to recruit in his

native air, and he returned to Orbe, accompanied by Braun, who did

not leave him till he had placed him in safety with his parents.

The following extracts from the correspondence between himself and

Braun give some account of this interval spent at home.

AGASSIZ TO BRAUN.

ORBE, May 26, 1827.

. . .Since I have been here, I have walked faithfully and have

collected a good number of plants which are not yet dry. I have

more than one hundred kinds, about twenty specimens of each. As

soon as they can be taken out of the press, I'll send you a few

specimens of each kind with a number attached so that you may

identify them. Take care that you do not displace the numbers in

opening the package. Should you want more of any particular kind

let me know; also whether Schimper wishes for any. . .At Neuchatel

I had the good fortune to find at least thirty specimens of

Bombinator obstetricans with the eggs. Tell Dr. Leuckart that I

will bring him some,--and some for you also. I kept several alive

laid in damp moss; after fourteen days the eggs were almost as

large as peas, and the little tadpoles moved about inside in all

directions. The mother stripped the eggs from her legs, and one of

the little tadpoles came out, but died for want of water. Then I

placed the whole mass of eggs in a vessel filled with water, and

behold! in about an hour some twenty young ones were swimming

freely about. I shall spare no pains to raise them, and I hope, if

I begin aright, to make fine toads of them in the end. My oldest

sister is busy every day in making drawings for me to illustrate

their gradual development. . .I dissect now as much and on as great

a variety of subjects as possible. This makes my principal

occupation. I am often busy too with Oken. His "Natur-philosophie"

gives me the greatest pleasure. I long for my box, being in need of

my books, which, no doubt, you have sent. Meantime, I am reading

something of Universal History, and am not idle, as you see. But I

miss the evenings with you and Schimper at Heidelberg, and wish I

were with you once more. I am afraid when that happy time does

come, it will be only too short. . .

BRAUN TO AGASSIZ.

HEIDELBERG, May, 1827.

. . .On Thursday evening, the 10th, I reached Heidelberg. The

medical lectures did not begin till the second week of May, so that

I have missed little, and almost regret having returned so soon. . .

I passed the last afternoon in Basel very pleasantly with Herr

Roepper, to whom I must soon write. He gave me a variety of

specimens, showed me many beautiful things, and told me much that

was instructive. He is a genuine and excellent botanist, and no

mere collector like the majority. Neither is he purely an observer

like Dr. Bischoff, but a man who thinks. . .Dr. Leuckart is in

raptures about the eggs of the "Hebammen Krote," and will raise

them. . .Schweiz takes your place in our erudite evening meetings.

I have been lecturing lately on the metamorphosis of plants, and

Schimper has propounded an entirely new and very interesting

theory, which will, no doubt, find favor with you hereafter, about

the significance of the circular and longitudinal fibres in

organisms. Schimper is fruitful as ever in poetical and

philosophical ideas, and has just now ventured upon a natural

history of the mind. We have introduced mathematics also, and he

has advanced a new hypothesis about comets and their long tails. . .

Our chief botanical occupation this summer is the careful

observation of all our plants, even the commonest, and the

explanation of whatever is unusual or enigmatical in their

structure. We have already cracked several such nuts, but many

remain to be opened. All such puzzling specimens are spread on

single sheets and set aside. . .But more of this when we are

together again. . .Dr. Leuckart begs you to study carefully the

"Hebammen Unke;"* (* Bombinator obstetricans referred to in a

former letter.) to notice whether the eggs are already fecundated

when they are in the earth, or whether they copulate later in the

water, or whether the young are hatched on land, and what is their

tadpole condition, etc. All this is still unknown. . .

AGASSIZ TO BRAUN.

ORBE, June 10, 1827.

. . .Last week I made a very pleasant excursion. You will remember

that I have often spoken to you of Pastor Mellet at Vallorbe, who

is much interested in the study of the six-legged insects. He

invited me to go to Vallorbe with him for some days, and I passed a

week there, spending my time most agreeably. We went daily on a

search after insects; the booty was especially rich in beetles and

butterflies. . .I examined also M. Mellet's own most excellent

collection of beetles and butterflies very carefully. He has many

beautiful things, but almost exclusively Swiss or French, with a

few from Brazil,--in all about 3,000 species. He gave me several,

and promises more in the autumn. . .He knows his beetles

thoroughly, and observes their habits, haunts, and changes (as far

as he can) admirably well. It is a pity though that while his

knowledge of species is so accurate, he knows nothing of

distribution, classification, or general relations. I tried to

convince him that he ought to collect snails, slugs, and other

objects of natural history, in the hope that he might gain thereby

a wider insight. But he would not listen to it; he said he had

enough to do with his Vermine.

My brother writes me that my box has arrived in Neuchatel. As I am

going there soon I will take it then. I rejoice in the thought of

being in Neuchatel, partly on account of my brother, Arnold

(Guyot), and other friends, and partly that I may study the fishes

of our Swiss lakes. The species Cyprinus and Corregonus with their

allies, including Salmo, are, as you know, especially difficult. I

will preserve some small specimens in alcohol, and, if possible,

dissect one of each, in order to satisfy myself as to their

identity or specific variety. As the same kinds have received

different names in different lakes, and since even differences of

age have led to distinct designations, I will note all this down

carefully. When I have made it clear to myself, I will send you a

catalogue of the kinds we possess, specifying at the same time the

lakes in which they occur. As I am on the chapter of fishes, I will

ask you:

1. What are the gill arches?

2. What the gill blades?

3. What is the bladder in fishes?

4. What is the cloaca in the egg-laying animals?

5. What signify the many fins of fishes?

6. What is the sac which surrounds the eggs in Bombinator obstetricans?

. . .Tell Dr. Leuckart I have already put aside for him the

Corregonus umbla (if such it be), but can get no Silurus glanis.

I suppose you continue to come together now and then in the evening

. . .Make me a sharer in your new discoveries. Have you finished

your essay on the physiology of plants, and what do you make of

it?. . .

BRAUN TO AGASSIZ.

CARLSRUHE, Whitsuntide, Monday, 1827.

. . .I am in Carlsruhe, and as the package has not gone yet, I add

a note. I have been analyzing and comparing all sorts of plants in

our garden to-day, and I wish you had been with me. On my last

sheet I send some nuts for you to pick, some wholly, some half,

others not at all, cracked. Schimper is lost in the great

impenetrable world of suns, with their planets, moons, and comets;

he soars even into the region of the double stars, the milky way,

and the nebulae.

On a loose sheet come the "nuts to pick." It contains a long list

of mooted questions, a few of which are given here to show the

exchange of thought between Agassiz and his friend, the one

propounding zoological, the other botanical, puzzles. Although most

of the problems were solved long ago, it is not uninteresting to

follow these young minds in their search after the laws of

structure and growth, dimly perceived at first, but becoming

gradually clearer as they go on. The very first questions hint at

the law of Phyllotaxis, then wholly unknown, though now it makes a

part of the most elementary instruction in botany.* (* Botany owes

to Alexander Braun and Karl Schimper the discovery of this law, by

which leaves, however crowded, are so arranged around the stem as

to divide the space with mathematical precision, thus giving to

each leaf its fair share of room for growth.)

"1. Where is the first diverging point of the stems and roots in

plants, that is to say, the first geniculum?

"2. How do you explain the origin of those leaves on the stem

which, not arising from distinct geniculi, are placed spirally or

scattered around the stem?

"3. Why do some plants, especially trees (contrary to the ordinary

course of development in plants), blossom before they have put

forth leaves? (Elm-trees, willow-trees, and fruit-trees.)

"4. In what succession does the development of the organs of the

flower take place?--and their formation in the bud? (Compare

Campanula, Papaver.)

"5. What are the leaves of the Spergula?

"6. What are the tufted leaves of various pine-trees? (Pinus

sylvestris, Strobus, Larix, etc.). . .

"8. What is individuality in plants?"

The next letter contains Agassiz's answer to Dr. Leuckart's

questions concerning the eggs he had sent him, and some farther

account of his own observations upon them.

AGASSIZ TO BRAUN.

NEUCHATEL, June 20, 1827.

. . .Now you shall hear what I know of the "Hebammen Krote." How

the fecundation takes place I know not, but it must needs be the

same as in other kinds of the related Bombinator; igneus throws out

almost as many eggs hanging together in clusters as obstetricans;

fuscus throws them out from itself in strings (see Roseld's

illustration). . .I have now carefully examined the egg clusters of

obstetricans; all the eggs are in one string and hang together.

This string is a bag, in which the eggs lie inclosed at different

distances, though they seem in the empty space to be fallen,

thread-like, together. But if you stretch the thread and press the

eggs, they change their places, and you can distinctly see that

they lie free in the bag, having their own membranous envelopes

corresponding to those of other batrachian eggs. Surely this

species seeks the water at the time of fecundation, for so do all

batrachians, the water being indeed a more fitting medium for

fecundation than the air. . .It is certain that the eggs were

already fecundated when we found them in the ground, for later, I

found several not so far advanced as those you have, and yet after

three weeks I had tadpoles from them. In those eggs which were in

the lowest stage of development (how they may be earlier, nescio),

nothing was clearly visible; they were simply little yellow balls.

After some days, two small dark spots were to be seen marking the

position of the eyes, and a longitudinal streak indicated the

dorsal ridge. Presently everything became more distinct; the mouth

and the nasal opening, the eyes and the tail, which lay in a half

circle around the body; the skin was so transparent that the

beating of the heart and the blood in the vessels could be easily

distinguished; the yolk and the yolk sac were meanwhile sensibly

diminished. The movements of the little animal were now quite

perceptible,--they were quick and by starts. After three or four

weeks the eggs were as large as peas; the bags had burst at the

spots where the eggs were attached, and the little creatures filled

the egg envelopes completely. They moved incessantly and very

quickly. Now the female stripped off the eggs from her legs; she

seemed very uneasy, and sprang about constantly in the tank, but

grew more quiet when I threw in more water. The eggs were soon

free, and I laid them in a shallow vessel filled with fresh water.

The restlessness among them now became greater, and behold! like

lightning, a little tadpole slipped out of its egg, paused

astonished, gazed on the greatness of the world, made some

philanthropic observations, and swam quickly away. I gave them

fresh water often, and tender green plants as well as bread to eat.

They ate eagerly. Up to this time their different stages of

development had been carefully drawn by my sister. I now went to

Vallorbe; they promised at home to take care of my young brood, but

when I returned the tadpoles had been forgotten, and I found them

all dead; not yet decayed, however, and I could therefore preserve

them in alcohol. The gills I have never seen, but I will watch to

see whether they are turned inward. . .

BRAUN TO AGASSIZ.

CARLSRUHE, August 9, 1827.

. . .This is to tell you that I have determined to leave Heidelberg

in the autumn and set forth on a pilgrimage to Munich, and that I

invite you to be my traveling companion. Judging by a

circumstantial letter from Dollinger, the instruction in the

natural sciences leaves nothing to be desired there. Add to this

that the lectures are free, and the theatre open to students at

twenty-four kreutzers. No lack of advantages and attractions,

lodgings hardly more expensive than at Heidelberg, board equally

cheap, beer plenty and good. Let all this persuade you. We shall

hear Gruithuisen in popular astronomy, Schubert in general natural

history, Martius in botany, Fuchs in mineralogy, Seiber in

mathematics, Starke in physics, Oken in everything (he lectures in

winter on the philosophy of nature, natural history, and

physiology). The clinical instruction will be good. We shall soon

be friends with all the professors. The library contains whatever

is best in botany and zoology, and the collections open to the

public are very rich. It is not known whether Schelling will

lecture, but at all events certain of the courses will be of great

advantage. Then little vacation trips to the Salzburg and

Carinthian Alps are easily made from there! Write soon whether you

will go and drink Bavarian beer and Schnapski with me, and write

also when we are to see you in Heidelberg and Carlsruhe. Remind me

then to tell you about the theory of the root and poles in plants.

As soon as I have your answer we will bespeak our lodgings from

Dollinger, who will attend to that for us. Shall we again house

together in one room, or shall we have separate cells in one comb,

namely, under the same roof? The latter has its advantages for

grass-gatherers and stone-cutters like ourselves. . .Hammer away

industriously at all sorts of rocks. I have collected at Auerbach,

Weinheim, Wiesloch, etc. But before all else, observe carefully and

often the wonderful structure of plants, those lovely children of

the earth and sky. Ponder them with child-like mind, for children

marvel at the phenomena of nature, while grown people often think

themselves too wise to wonder, and yet they know little more than

the children. But the thoughtful student recognizes the truth of

the child's feeling, and with his knowledge of nature his wonder

does but grow more and more. . .

Agssiz accepted with delight his friend's proposition, and toward

the end of October, 1827, he and Braun left Carlsruhe together for

the University of Munich. His first letter to his brother is given

in full, for though it contains crudities at which the writer

himself would have smiled in after life, it is interesting as

showing what was the knowledge possessed in those days by a clever,

well-informed student of natural history.

TO HIS BROTHER AUGUSTE.

MUNICH, November 5, 1827.

. . .At last I am in Munich. I have so much to tell you that I

hardly know where to begin. To be sure that I forget nothing,

however, I will give things in their regular sequence. First, then,

the story of my journey; after that, I will tell you what I am

doing here. As papa has, of course, shown you my last letter, I

will continue where I left off. . .

From Carlsruhe we traveled post to Stuttgart, where we passed the

greater part of the day in the Museum, in which I saw many things

quite new to me; a llama, for instance, almost as large as an ass.

You know that this animal, which is of the genus Camelus, lives in

South America, where it is to the natives what the camel is to the

Arab; that is to say, it provides them with milk, wool, and meat,

and is used by them, moreover, for driving and riding. There was a

North American buffalo of immense size; also an elephant from

Africa, and one from Asia; beside these, a prodigious number of

gazelles, deer, cats, and dogs; skeletons of a hippopotamus and an

elephant; and lastly the fossil bones of a mammoth. You know that

the mammoth is no longer found living, and that the remains

hitherto discovered lead to the belief that it was a species of

carnivorous elephant. It is a singular fact that some fishermen,

digging recently on the borders of the Obi, in Siberia, found one

of these animals frozen in a mass of ice, at a depth of sixty feet,

so well preserved that it was still covered with hair, as in life.

They melted the ice to remove the animal, but the skeleton alone

remained complete; the hide was spoiled by contact with the air,

and only a few pieces have been kept, one of which is in the Museum

at Stuttgart. The hairs upon it are as coarse as fine twine, and

nearly a foot long. The entire skeleton is at St. Petersburg in the

Museum, and is larger than the largest elephant. One may judge by

that what havoc such an animal must have made, if it was, as its

teeth show it to have been, carnivorous. But what I would like to

know is how this animal could wander so far north, and then in what

manner it died, to be frozen thus, and remain intact, without

decomposing, perhaps for countless ages. For it must have belonged

to a former creation, since it is nowhere to be found living, and

we have no instance of the disappearance of any kind of animal

within the historic period. There were, besides, many other kinds

of fossil animals. The collection of birds is very beautiful, but

it is a pity that many of them are wrongly named. I corrected a

number myself. . .From Stuttgart we went to Esslingen, where we

were to visit two famous botanists. One was Herr Steudel; a sombre

face, with long overhanging black hair, almost hiding the eyes,--a

very Jewish face. He knows every book on botany that appears, has

read them all, but cares little to see the plants themselves; in

short, he is a true closet student. He has a large herbarium,

composed in great part of plants purchased or received as gifts.

The other, Professor Hochstetter, is an odd little man, stepping

briskly about in his high boots, and having always a half

suppressed smile on his hips whenever he takes the pipe from

between his teeth. A very good man, however, and extremely

obliging; he offered us every civility. As we desired not only to

make their acquaintance, but to win from these botanists at least a

few grasses, we presented ourselves like true commis voyageurs,

with dried herbs to sell, each of us having a package of plants

under his arm,--mine being Swiss, gathered last summer, Braun's

from the Palatinate. We gave specimens to each, and received in

exchange from Steudel some American plants; from Hochstetter some

from Bohemia, and others from Moravia, his native country. From

Esslingen we were driven to Goeppingen, in the most frightful

weather possible; it rained, snowed, froze, blew, all at once. It

was a pity, since our road lay through one of the prettiest valleys

I have ever seen, watered by the Neckar, and bordered on both sides

by mountains of singular form and of considerable height. They are

what the Wurtembergers call the Suabian Alps, but I think that

Chaumont is higher than the loftiest peak of their Alps. Here we

found an old Heidelberg acquaintance, whose father owns a superb

collection of fossils, especially of shells and zoophytes. He has

also quite a large collection of shells from the Adriatic Sea, but

among these last not one was named. As we knew them, we made it our

duty to arrange them, and in three hours his whole collection was

labeled. Since he has duplicates of almost everything, he promised,

as soon as he should have time, to make a selection from these and

send them to us. Could we have stayed longer we might have picked

out what we pleased, for he placed his collection at our disposal.

But we were in haste to arrive here, so we begged him to send us,

at his leisure, whatever he could give us.

Thence we continued our journey by post, because it still rained,

and the roads were so detestable that with the best will in the

world we could not have made our way on foot. In the evening we

reached Ulm, where, owing to the late hour, we saw almost nothing

except the famous belfry of the cathedral, which was distinctly

visible as we entered the city. After supper we continued our

journey, still by post, wishing to be in Munich the next day. I

have never seen anything more beautiful than the view as we left

Ulm. The moon had risen and shone upon the belfry like broad

daylight. On all sides extended a wide plain, unbroken by a single

inequality, so far as the eye could distinguish, and cut by the

Danube, glittering in the moonbeams. We crossed the plain during

the night, and reached Augsburg at dawn. It is a beautiful city,

but we merely stopped there for breakfast, and saw the streets only

as we passed through them. On leaving Augsburg, the Tyrolean Alps,

though nearly forty leagues away, were in sight. About eighteen

leagues off was also discernible an immense forest; of this we had

a nearer view as we advanced, for it encircles Munich at some

distance from the town. We arrived here on Sunday, the 4th, in the

afternoon. . .My address is opposite the Sendlinger Thor Number 37.

I have a very pretty chamber on the lower floor with an alcove for

my bed. The house is situated outside the town, on a promenade,

which makes it very pleasant. Moreover, by walking less than a

hundred yards, I reach the Hospital and the Anatomical School, a

great convenience for me when the winter weather begins. One thing

gives me great pleasure: from one of my windows the whole chain of

the Tyrolean Alps is visible as far as Appenzell; and as the

country is flat to their very base, I see them better than we see

our Alps from the plain. It is a great pleasure to have at least a

part of our Swiss mountains always in sight. To enjoy it the more,

I have placed my table opposite the window, so that every time I

lift my head my eyes rest on our dear country. This does not

prevent me from feeling dull sometimes, especially when I am alone,

but I hope this will pass off when my occupations become more

regular. . .

A far more stimulating intellectual life than that of Heidelberg

awaited our students at Munich. Among their professors were some of

the most original men of the day,--men whose influence was felt all

over Europe. Dollinger lectured on comparative anatomy and kindred

subjects; Martius and Zuccarini on botany. Martius gave, besides,

his so-called "Reise-Colleg," in which he instructed the students

how to observe while on their travels. Schelling taught philosophy,

the titles of his courses in the first term being, "Introduction to

Philosophy" and "The Ages of the World"; in the second, "The

Philosophy of Mythology" and "The Philosophy of Revelation."

Schelling made a strong impression upon the friends. His manner was

as persuasive as his style was clear, and his mode of developing

his subject led his hearers along with a subtle power which did not

permit fatigue. Oken lectured on general natural history,

physiology, and zoology, including his famous views on the

philosophy of nature (Natur-philosophie). His lectures gave

occasion for much scientific discussion, the more so as he brought

very startling hypotheses into his physiology, and drew from them

conclusions which even upon his own showing were not always in

accordance with experience. "On philosophical grounds," he was wont

to say, when facts and theory thus confronted each other, "we must

so accept it." Oken was extremely friendly with the students, and

Agassiz, Braun, and Schimper (who joined them at Munich) passed an

evening once a week at his house, where they listened to scientific

papers or discussed scientific matters, over a pipe and a glass of

beer. They also met once a week to drink tea at the house of

Professor von Martius, where, in like manner, the conversation

turned upon scientific subjects, unless something interesting in

general events gave it a different turn. Still more beloved was

Dollinger, whose character they greatly esteemed and admired while

they delighted in his instruction. Not only did they go to him

daily, but he also came often to see them, bringing botanical

specimens to Braun, or looking in upon Agassiz's breeding

experiments, in which he took the liveliest interest, being always

ready with advice or practical aid. The fact that Agassiz and Braun

had their room in his house made intercourse with him especially

easy. This room became the rendezvous of all the aspiring, active

spirits among the young naturalists at Munich, and was known by the

name of "The Little Academy." Schimper, no less than the other two,

contributed to the vivid, enthusiastic intellectual life, which

characterized their meetings. Not so happy as Agassiz and Braun in

his later experience, the promise of his youth was equally

brilliant; and those who knew him in those early days remember his

charm of mind and manner with delight. The friends gave lectures in

turn on various subjects, especially on modes of development in

plants and animals. These lectures were attended not only by

students, but often by the professors.

Among Agassiz's intimate friends in Munich, beside those already

mentioned, was Michahelles, the distinguished young zoologist and

physician, whose early death in Greece, where he went to practice

medicine, was so much regretted. Like Agassiz, he was wont to turn

his room into a menagerie, where he kept turtles and other animals,

brought home, for the most part, from his journeys in Italy and

elsewhere. Mahir, whose name occurs often in the letters of this

period, was another college friend and fellow-student, though

seemingly Agassiz's senior in standing, if not in years, for he

gave him private instruction in mathematics, and also assisted him

in his medical studies.

TO HIS SISTER CECILE,

MUNICH, November 20, 1827.

. . .I will tell you in detail how my time is spent, so that when

you think of me you may know where I am and what I am doing. In the

morning from seven to nine I am at the Hospital. From nine to

eleven I go to the Library, where I usually work at that time

instead of going home. From eleven till one o'clock I have

lectures, after which I dine, sometimes at one place, sometimes at

another, for here every one, that is, every foreigner, takes his

meals in the cafes, paying for the dinner on the spot, so that he

is not obliged to go always to the same place. In the afternoon I

have other lectures on various subjects, according to the days,

from two or three till five o'clock. These ended, I take a walk

although it is then dark. The environs of Munich are covered with

snow, and the people have been going about in sleighs these three

weeks. When I am frozen through I come home, and set to work to

review my lectures of the day, or I write and read till eight or

nine o'clock. Then I go to my cafe for supper. After supper I am

glad to return to the house and go to bed.

This is the course of my daily life, with the single exception that

sometimes Braun and I pass an evening with some professor,

discussing with all our might and main subjects of which we often

know nothing; this does not, however, lessen the animation of the

talk. More often, these gentlemen tell us of their travels, etc. I

enjoy especially our visits to M. Martius, because he talks to us

of his journey to Brazil, from which he returned some years ago,

bringing magnificent collections, which he shows us whenever we

call upon him. Friday is market day here, and I never miss going to

see the fishes to increase my collection. I have already obtained

several not to be found in Switzerland; and even in my short stay

here I have had the good fortune to discover a new species, of

which I have made a very exact description, to be printed in some

journal of natural history. Were my dear Cecile here, I should have

begged her to draw it nicely for me. That would have been pleasant

indeed. Now I must ask a stranger to do it, and it will have by no

means the same value in my eyes. . .

TO HIS BROTHER AUGUSTE.

MUNICH, December 26, 1827.

. . .After my long fast from news of you, your letter made me very

happy. I was dull besides, and needed something to cheer me. . .

Since my talk about natural history does not bore you, I want to

tell you various other things about it, and also to ask you to do

me a favor. I have stuffed a superb otter lately; next week I shall

receive a beaver, and I have exchanged all my little toads from

Neuchatel for reptiles from Brazil and Java. One of our professors

here, who is publishing a natural history of reptiles, will

introduce in his work my description of that species, and my

observations upon it. He has already had lithographed those

drawings of eggs that Cecile made for me, as well as the colored

drawings made for me by Braun's sister when I was at Carlsruhe. My

collection of fishes is also much increased, but I have no

duplicates left of the species I brought with me. I have exchanged

them all. I should therefore be greatly obliged if you would get me

some more of the same. I will tell you what kinds I want, and how

you are to forward them. I have still at Cudrefin several jars of

thick green glass. When you go there take them away with you, fill

them with alcohol, and put into them as many of these fishes as you

can find for me. Put something between every two specimens, to

prevent them from rubbing against each other; pack them in a little

box wrapped in hay, and send them either by a good opportunity or

in the least expensive way. The kinds I want are [here follows the

list]. . .It will interest you to know that I am working with a

young Dr. Born upon an anatomy and natural history of the

fresh-water fishes of Europe. We have already gathered a great deal

of material, and I think by the spring, or in the course of the

summer, we shall be able to publish the first number. This will

bring in a little ready money for a short journey in the vacation.

I earnestly advise you to while away your leisure hours with study.

Read much, but only good and useful books. I promised to send you

something; do not think, because I have not done so yet, that I

have forgotten it. On the contrary, the difficulty of choosing is

the cause of the delay; but I will make farther inquiry as to what

will suit you best and you shall have my list. Meantime remember to

read Say, and if you have not already begun it, do not put it off.

Remember that statistical and political knowledge alone

distinguishes the true merchant from the mere tradesman, and guides

him in his undertakings. . .A merchant familiar with the products

of a country, its resources, its commercial and political relations

with other countries, is much less likely to enter into

speculations based on false ideas, and therefore of doubtful issue.

Write me about what you are reading and about your plans and

projects, for I can hardly believe that any one could exist without

forming them: I, at least, could not.

The last line of this letter betrays the restless spirit of

adventure growing out of the desire for larger fields of activity

and research. Tranquilized for a while in the new and more

satisfying intellectual life of Munich, it stirred afresh from time

to time, not without arousing anxiety in friends at home, as we

shall see. The letter to which the following is an answer has not

been found.

FROM HIS MOTHER.

ORBE, January 8, 1828.

. . .Your letter reached me at Cudrefin, where I have been passing

ten days. With what pleasure I received it,--and yet I read it with

a certain sadness too, for there was something of ennui, I might

say of discontent, in the tone. . .Believe me, my dear Louis, your

attitude is a wrong one; you see everything in shadow. Consider

that you are exactly in the position you have chosen for yourself;

we have in no way opposed your plans. We have, on the contrary,

entered into them with readiness, saying amen to your proposals,

only insisting upon a profession that would make us easy about your

future, persuaded as we are that you have too much energy and

uprightness not to wish to fill honorably your place in society.

You left us a few months ago with the assurance that two years

would more than suffice to complete your medical studies. You chose

the university which offered, as you thought, the most ample means

to reach your end; and now, how is it that you look forward only

with distaste to the practice of medicine? Have you reflected

seriously before setting aside this profession? Indeed, we cannot

consent to such a step. You would lose ground in our opinion, in

that of your family, and in that of the public. You would pass for

an inconsiderate, fickle young fellow, and the slightest stain on

your reputation would be a mortal blow to us. There is one way of

reconciling all difficulties,--the only one in my opinion. Complete

your studies with all the zeal of which you are capable, and then,

if you have still the same inclination, go on with your natural

history; give yourself wholly up to it should that be your wish.

Having two strings to your bow, you will have the greater facility

for establishing yourself. Such is your father's way of thinking as

well as mine. . .Nor are you made to live alone, my child. In a

home only is true happiness to be found; there you can settle

yourself to your liking. The sooner you have finished your studies,

the sooner you can put up your tent, catch your blue butterfly, and

metamorphose her into a loving housewife. Of course you will not

gather roses without thorns; life consists of pains and pleasures

everywhere. To do all the good you can to your fellow-beings, to

have a pure conscience, to gain an honorable livelihood, to procure

for yourself by work a little ease, to make those around you happy,

--that is true happiness; all the rest but mere accessories and

chimeras. . .

TO HIS MOTHER.

MUNICH, February 3, 1828.

. . .You know well to whom you speak, dear mother, and how you must

bait your hook in order that the fish may rise. When you paint it,

I see nothing above domestic happiness, and am convinced that the

height of felicity is to be found in the bosom of your family,

surrounded by little marmots to love and caress you. I hope, too,

to enjoy this happiness in time. . .But the man of letters should

seek repose only when he has deserved it by his toil, for if once

he anchor himself, farewell to energy and liberty, by which alone

great minds are fostered. Therefore I have said to myself, that I

would remain unmarried till my work should assure me a peaceful and

happy future. A young man has too much vigor to bear confinement so

soon; he gives up many pleasures which he might have had, and does

not appreciate at their just value those which he has. As it is

said that the vaurien must precede the bon sujet, so I believe that

for the full enjoyment of sedentary life one must have played the

vagabond for a while.

This brings me to the subject of my last letter. It seems that you

have misunderstood me, for your answer grants me after all just

what I ask. You think that I wish to renounce entirely the study of

medicine? On the contrary, the idea has never occurred to me, and,

according to my promise, you shall have one of these days a doctor

of medicine as a son. What repels me is the thought of practicing

medicine for a livelihood, and here you give me free rein just

where I wanted it. That is, you consent that I should devote myself

wholly to the natural sciences should this career offer me, as I

hope it may, a more favorable prospect. It requires, for instance,

but two or three years to go around the world at government

expense. I will levy contributions on all my senses that not a

single chance may escape me for making interesting observations and

fine collections, so that I also may be ranked among those who have

enlarged the boundaries of science. With that my future is secured,

and I shall return content and disposed to do all that you wish.

Even then, if medicine had gained greater attraction for me, there

would still be time to begin the practice of it. It seems to me

there is nothing impracticable in this plan. I beg you to think of

it, and to talk it over with papa and with my uncle at Lausanne

. . .I am perfectly well and as happy as possible, for I feed in

clover here on my favorite studies, with every facility at my

command. If you thought my New Year's letter depressed, it was only

a momentary gloom due to the memories awakened by the day. . .

FROM HIS FATHER.

ORBE, February 21, 1828.

Your mother's last letter, my dear Louis, was in answer to one from

you which crossed it on the way, and gave us, so far as your health

and contentment are concerned, great satisfaction. Yet our

gratification lacks something; it would be more complete had you

not a mania for rushing full gallop into the future. I have often

reproved you for this, and you would fare better did you pay more

attention to my reproof. If it be an incurable malady with you, at

all events do not force your parents to share it. If it be

absolutely essential to your happiness that you should break the

ice of the two poles in order to find the hairs of a mammoth, or

that you should dry your shirt in the sun of the tropics, at least

wait till your trunk is packed and your passports are signed before

you talk with us about it. Begin by reaching your first aim, a

physician's and surgeon's diploma. I will not for the present hear

of anything else, and that is more than enough. Talk to us, then in

your letters, of your friends, of your personal life, of your wants

(which I am always ready to satisfy), of your pleasures, of your

feeling for us, but do not put yourself out of our reach with your

philosophical syllogisms. My own philosophy is to fulfill my duties

in my sphere, and even that gives me more than I can do. . .

The Vaudois "Society of Public Utility" has just announced an

altogether new project, that of establishing popular libraries. A

committee consisting of eight members, of whom I have the honor to

be one, is nominated under the presidency of M. Delessert for the

execution of this scheme. What do you think of the idea? To me it

seems a delicate matter. I should say that before we insist upon

making people read we must begin by preparing them to read

usefully?. . .

TO HIS FATHER.

MUNICH, March 3, 1828.

. . .What you tell me of the "Society of Public Utility" has

aroused in me a throng of ideas, about which I will write you when

they are a little more mature. Meanwhile, please tell me: 1. What

is this Society? 2. Of what persons is it composed? 3. What is its

principal aim? 4. What are the popular libraries to contain, and

for what class are they intended? I believe this project may be of

the greatest service to our people, and it is on this account that

I desire farther details that I may think it over carefully. Tell

me, also, in what way you propose to distribute your libraries at

small expense, and how large they are to be. . .

I could not be more satisfied than I am with my stay here. I lead a

monotonous but an exceedingly pleasant life, withdrawn from the

crowd of students and seeing them but little. When our lectures are

over we meet in the evening at Braun's room or mine, with three or

four intimate acquaintances, and talk of scientific matters, each

one in his turn presenting a subject which is first developed by

him, and then discussed by all. These exercises are very

instructive. As my share, I have begun to give a course of natural

history, or rather of pure zoology. Braun talks to us of botany,

and another of our company, Mahir, who is an excellent fellow,

teaches us mathematics and physics in his turn. In two months our

friend Schimper, whom we left at Heidelberg, will join us, and he

will then be our professor of philosophy. Thus we shall form a

little university, instructing each other and at the same time

learning what we teach more thoroughly, because we shall be obliged

to demonstrate it. Each session lasts two or three hours, during

which the professor in charge retails his merchandise without aid

of notes or book. You can imagine how useful this must be in

preparing us to speak in public and with coherence; the experience

is the more important, since we all desire nothing so much as

sooner or later to become professors in very truth, after having

played at professor in the university.

This brings me naturally to my projects again. Your letter made me

feel so keenly the anxiety I had caused you by my passion for

travel, that I will not recur to it; but as my object was to make

in that way a name that would win for me a professorship, I venture

upon another proposition. If during the course of my studies I

succeed in making myself known by a work of distinction, will you

not then consent that I shall study, at least during one year, the

natural sciences alone, and then accept a professorship of natural

history, with the understanding that in the first place, and in the

time agreed upon, I shall take my Doctor's degree? This is, indeed,

essential to my obtaining what I wish, at least in Germany. You

will object that, before thinking of anything beyond, I ought first

to fulfill the condition. But let me say that the more clearly a

man sees the road before him, the less likely he is to lose his way

or take the wrong turn,--the better he can divide his stages and

his resting-places. . .

FROM HIS FATHER.

ORBE, March 25, 1828.

. . .I have had a long talk about you with your uncle. He does not

at all disapprove of your letters, of which I told him the

contents. He only insists, as we do, on the necessity of a settled

profession as absolutely essential to your financial position.

Indeed, the natural sciences, however sublime and attractive, offer

nothing certain in the future. They may, no doubt, be your golden

bridge, or you may, thanks to them, soar very high, but--modern

Icarus--may not also some adverse fortune, an unexpected loss of

popularity, or, perhaps, some revolution fatal to your philosophy,

bring you down with a somersault, and then you would not be sorry

to find in your quiver the means of gaining your bread. Agreed that

you have now an invincible repugnance to the practice of medicine,

it is evident from your last two letters that you would have no

less objection to any other profession by which money is to be

made, and, besides, it is too late to make another selection. This

being so, we will come to an understanding in one word: Let the

sciences be the balloon in which you prepare to travel through

higher regions, but let medicine and surgery be your parachutes. I

think, my dear Louis, you cannot object to this way of looking at

the question and deciding it. In making my respects to the

professor of zoology, I have the pleasure to tell him that his

uncle was delighted with his way of passing his evenings, and

congratulates him with all his heart on his choice of a recreation.

Enough of this chapter. I close it here, wishing you most heartily

courage, health, success, and, above all, contentment. . .

Upon this follows the answer to Louis's request for details about

the "Society of Public Utility." It shows the intimate exchange of

thought between father and son on educational subjects, but it is

of too local an interest for reproduction here.

The Easter vacation was devoted to a short journey, some account of

which will be found in the next letter. The traveling party

consisted of Agassiz, Braun, and Schimper, with two other students,

who did not, however, remain with them during the whole trip.

TO HIS FATHER.

MUNICH, May 15, 1828.

. . .Pleasant as my Easter journey was, I will give you but a brief

account of it, for my enjoyment was so connected with my special

studies that the details would only be tiresome to you. You know

who were my traveling companions, so I have only to tell you of our

adventures, assuredly not those of knights errant or troubadours.

Could these gentry have been resuscitated, and have seen us

starting forth in blouses, with bags or botanical boxes at our

backs and butterfly-nets in our hands, instead of lance and

buckler, they could hardly have failed to look down upon us with

pity from the height of their grandeur.

The first day brought us to Landshut, where was formerly the

university till it was transferred, ten years ago, to Munich. We

had the pleasure of finding along our road most of the early spring

plants. The weather was magnificent, and nature seemed to smile

upon her votaries. . .We stopped on the way but one day, at

Ratisbon, to visit some relations of Braun's, with whom we promised

to spend several days on our return. Learning on our arrival at

Nuremberg that the Durer festival, which had been our chief

inducement for this journey, would not take place under eight or

ten days, we decided to pass the intervening time at Erlangen, the

seat, as you know, of a university. I do not know if I have already

told you that among German students the exercise of hospitality

toward those who exchange visits from one university to another is

a sacred custom. It gives offense, or is at least looked upon as a

mark of pride and disdain, if you do not avail yourself of this. We

therefore went to one of the cafe's de reunion, and received at

once our tickets for lodgings. We passed six days at Erlangen most

agreeably, making a botanical excursion every day. We also called

upon the professors of botany and zoology, whom we had already seen

at Munich, and by whom we were most cordially received. The

professor of botany, M. Koch, invited us to a very excellent

dinner, and gave us many rare plants not in our possession before,

while M. Wagner was kind enough to show us in detail the Museum and

the Library.

At last came the day appointed for the third centennial festival of

Durer. Everything was so arranged as to make it very brilliant, and

the weather was most favorable. I doubt if ever before were

collected so many painters in the same place. They gathered; as if

to vie with each other, from all nations, Russians, Italians,

French, Germans, etc. Beside the pupils of the Academy of Fine Arts

at Munich, I think that every soul who could paint, were it only

the smallest sketch, was there to pay homage to the great master.

All went in procession to the place where the monument is to be

raised, and the magistrates of the city laid the first stones of

the pedestal. To my amusement they cemented these first stones with

a mortar which was served in great silver platters, and made of

fine pounded porcelain mixed with champagne. In the evening all the

streets were illuminated; there were balls, concerts, and plays, so

that we must have been doubled or quadrupled to see everything. We

stayed some days longer at Nuremberg to visit the other curiosities

of the city, especially its beautiful churches, its manufactories,

etc., and then started on our return to Ratisbon. . .

It was not without a definite purpose that Agassiz had written to

his father some weeks before, "Should I during the course of my

studies succeed in making myself known by a distinguished work,

would you not then consent that I should study for one year the

natural sciences alone?" Unknown to his parents, for whom he hoped

to prepare a delightful surprise, Agassiz had actually been engaged

for months on the first work which gave him distinction in the

scientific world; namely, a description of the Brazilian fishes

brought home by Martius and Spix from their celebrated journey in

Brazil. This was the secret to which allusion is made in the next

letter. To his disappointment an accident brought his undertaking

to the knowledge of his father and mother before it was completed.

He always had a boyish regret that his little plot had been

betrayed before the moment for the denouement arrived. The book was

written in Latin and dedicated to Cuvier.* (* "Selecta genera et

species piscium quos collegit et pingendos curavit Dr. J.W. de

Spix". Digessit, descripsit et observationibus illustravit Dr. L.

Agassiz.)

TO HIS BROTHER.

MUNICH, July 27, 1828.

. . .Various things which I have begun keep me a prisoner here.

Probably I shall not stir during the vacation, and shall even give

up the little trip in the Tyrol, which I had thought of making as a

rest from occupations that bind me very closely at present, but

from which I hope to free myself in the course of the holidays.

Don't be angry with me for not telling you at once what they are.

When you know, I hope to be forgiven for keeping you so long in the

dark. I have kept it a secret from papa too, though in his last

letter he asks me what is my especial work just now. A few months

more of patience, and I will give you a strict account of my time

since I came here, and then I am sure you will be satisfied with

me. I only wish to guard against one thing: do not take it into

your head that I am about to don the fool's cap suddenly and

surprise you with a Doctor's degree; that would be going a little

too fast, nor do I think of it yet. . .I want to remind you not to

let the summer pass without getting me fishes according to the list

in my last letter, which I hope you have not mislaid. You would

give me great pleasure by sending them as soon as possible. Let me

tell you why. M. Cuvier has announced the publication of a complete

work on all the known fishes, and in the prospectus he calls on

such naturalists as occupy themselves with ichthyology to send him

the fishes of the country where they live; he mentions those who

have already sent him collections, and promises duplicates from the

Paris Museum to those who will send him more. He names the

countries also from which he has received contributions, and

regrets that he has nothing from Bavaria. Now I possess several

specimens of all the native species, and have even discovered some

ten not hitherto known to occur here, beside one completely new to

science, which I have named Cyprinus uranoscopus on account of the

position of the eyes, placed on the top instead of the sides of the

head,--otherwise very like the gudgeon. I have therefore thought I

could not better launch myself in the scientific world than by

sending Cuvier my fishes with the observations I have made on their

natural history. To these I should like to add such rare Swiss

species as you can procure for me. So do not fail.

FROM HIS BROTHER.

NEUCHATEL, August 25, 1828.

. . .I received in good time, and with infinite delight, your

pleasant letter of July 27th. Its mysteries have however been

unveiled by Dr. Schinz, who came to the meeting of the Natural

History Society in Lausanne, where he met papa and my uncle, to

whom he pronounced the most solemn eulogiums on their son and

nephew, telling them at the same time what was chiefly occupying

you now. I congratulate you, my dear brother, but I confess that

among us all I am the least surprised, for my presentiments about

you outrun all this, and I hope soon to see them realized. In all

frankness I can assure you that the stoutest antagonists of your

natural history schemes begin to come over to your side. Among them

is my uncle here, who never speaks of you now but with enthusiasm.

What more can be said? I gave him your letter to read, and since

then he has asked me a dozen times at least if I had not forgotten

to forward the remittance you asked for, saying that I must not

delay it. The truth is, I have deferred writing till the last

moment, because I have not succeeded in getting your fishes, and

have always been hoping that I might be able to fulfill your

commission. I busied myself on your behalf with all the zeal and

industry of which I was capable, but quite in vain. The devil

seemed to be in it. The season of Bondelles was over two months

ago, and there are none to be seen; as to trout, I don't believe

one has been eaten in the whole town for six weeks. I am forever at

the heels of the fishermen, promising them double and treble the

value of the fish I want, but they all tell me they catch nothing

except pike. I have been to Cudrefin for lampreys, but found

nothing. Rodolphe* (* An experienced old boatman.) has been

paddling in the brook every day without success. I went to Sauge,

--no eels, no anything but perch and a few little cat-fish. Two

mortal Sundays did I spend, rod in hand, trying to catch bream,

chubs, etc. I did get a few, but they were not worth sending. Now

it is all over for this year, and we may as well put on mourning

for them; but I promise you that as soon as the spring opens I will

go to work, and you shall have all you want. If, in spite of

everything, your hopes are not realized, I shall be very sorry, but

rest assured that it is not my fault. . .

TO HIS SISTER CECILE.

MUNICH, October 29, 1828.

. . .I have never written you about what has engrossed me so

deeply; but since my secret is out, I ought not to keep silence

longer. That you may understand why I have entered upon such a work

I will go back to its origin. In 1817 the King of Bavaria sent two

naturalists, M. Martius and M. Spix, on an exploring expedition to

Brazil. Of M. Martius, with whom I always spend my Wednesday

evenings, I have often spoken to you. In 1821 these gentlemen

returned to their country laden with new discoveries, which they

published in succession. M. Martius issued colored illustrations of

all the unknown plants he had collected on his journey, while M.

Spix brought out several folio volumes on the monkeys, birds, and

reptiles of Brazil, the animals being drawn and colored, chiefly

life-size, by able artists. It had been his intention to give a

complete natural history of Brazil, but to the sorrow of all

naturalists he died in 1826. M. Martius, desirous to see the

completion of the work which his traveling companion had begun,

engaged a professor from Erlangen to publish the shells, and these

appeared last year. When I came to Munich there remained only the

fishes and insects, and M. Martius, who had learned something about

me from the professors to whom I was known, found me worthy to

continue the work of Spix, and asked me to carry on the natural

history of the fishes. I hesitated for a long time to accept this

honorable offer, fearing that the occupation might withdraw me too

much from my studies; but, on the other hand, the opportunity for

laying the foundation of a reputation by a large undertaking seemed

too favorable to be refused. The first volume is already finished,

and the printing was begun some weeks ago. You can imagine the

pleasure I should have had in sending it to our dear father and

mother before they had heard one word about it, or knew even of the

proposition. But I hope the premature disclosure of my secret

(indeed, to tell the truth, I had not imposed silence on M. Schinz,

not dreaming that he would see any one of the family) will not

diminish your pleasure in receiving the first work of your brother

Louis, which I hope to send you at Easter. Already forty colored

folio plates are completed. Will it not seem strange when the

largest and finest book in papa's library is one written by his

Louis? Will it not be as good as to see his prescription at the

apothecary's? It is true that this first effort will bring me in

but little; nothing at all, in fact, because M. de Martius has

assumed all the expenses, and will, of course, receive the profits.

My share will be a few copies of the book, and these I shall give

to the friends who have the first claim.

To his father Agassiz only writes of his work at this time: "I have

been very busy this summer, and I can tell you from a good source

(I have it from one of the professors himself) that the professors

whose lectures I have attended have mentioned me more than once, as

one of the most assiduous and best informed students of the

university; saying also that I deserved distinction. I do not tell

you this from ostentation, but only that you may not think I lose

my time, even though I occupy myself chiefly with the natural

sciences. I hope yet to prove to you that with a brevet of Doctor

as a guarantee, Natural History may be a man's bread-winner as well

as the delight of his life. . ."

In September Agassiz allowed himself a short interruption of his

work. The next letter gives some account of this second vacation

trip.

TO HIS PARENTS.

MUNICH, September 26, 1828.

. . .The instruction for the academic year closed at the end of

August, and our professors had hardly completed their lectures when

I began my Alpine excursion. Braun, impatient to leave Munich, had

already started the preceding day, promising to wait for me on the

Salzburg road at the first spot which pleased him enough for a

halt. That I might not keep him waiting, I begged a friend to drive

me a good day's journey, thinking to overtake Braun the first day

on the pleasant banks of the Lake of Chiem. My traveling companions

were the younger Schimper [Wilhelm], of whom I have spoken to you

(and who made a botanical journey in the south of France and the

Pyrenees two years ago), and Mahir, who drove us, with whom I am

very intimate; he is a medical student, and also a very

enthusiastic physicist. He gave me private lessons in mathematics

all winter, and was a member of our philomathic meetings. Braun had

not set out alone either, and his two traveling companions were

also friends of ours. One was Trettenbacher, a medical student

greatly given to sophisms and logic, but allowing himself to be

beaten in argument with the utmost good nature, though always

believing himself in the right; a thoroughly good fellow with all

that, and a great connoisseur of antiquities. The other was a young

student, More, from the ci-devant department of Mt. Tonnerre, who

devotes himself entirely to the natural sciences, and has chosen

the career of traveling naturalist. You can easily imagine that

this attracts me to him, but as he is only a beginner I am, as it

were, his mentor.

On the morning of our departure the weather was magnificent.

Driving briskly along we had various surmises as to where we should

probably meet our traveling companions, not doubting that, as we

hoped to reach the Lake of Chiem the same day, We should come

across them the day following on one of its pretty islands. But in

the afternoon the weather changed, and we were forced to seek

shelter from torrents of rain at Rosenheim, a charming town on the

banks of the Inn, where I saw for the first time this river of

Helvetic origin. I saluted it as a countryman of mine, and wished I

could change its course and send it back laden with my greetings.

The next day Mahir drove us as far as the shore of the lake. There

we parted from him, and took a boat to the islands, where we were

much disappointed not to find Braun and his companions. We thought

the bad weather of the day before (for here it had rained all day)

might have obliged them to make the circuit of the lake. However,

in order to overtake them before reaching Salzburg, we kept our

boatmen, and were rowed across to the opposite shore near

Grabenstadt, where we arrived at ten o'clock in the evening. In the

afternoon the weather had cleared a little, and the view was

beautiful as we pulled away from the islands and watched them fade

in the twilight. I also gathered much interesting information about

the inhabitants of the waters of this lake. Among others, I was

much pleased to find a cat-fish, taken in the lake by one of the

island fishermen, and also a kind of chub, not found in

Switzerland, and called by the fishermen here "Our Lady's Fish,"

because it occurs only on the shore of an island where there is a

convent, the nuns of which esteem it a great delicacy.

The third day we reached Traunstein, where, although it was Sunday,

there was a great horse fair. We looked with interest at the gay

Tyroleans, with the cock-feathers in their pointed hats, singing

and yodeling in the streets with their sweethearts on their arms.

Every now and then they let fall some sarcastic comment on our

accoutrements, which were indeed laughable enough to these people,

who had never seen anything beyond their own chalets, and for whom

an excursion from their mountains to a fair in the nearest town is

a journey. It was noon when we stopped at Traunstein, and from

there to Salzburg is but five leagues. Before reaching the

fortress, however, you must pass the great custom-house on the

Bavarian frontier, and fearing we might be delayed there too long

by the stupid Austrian officials, and thus be prevented from

entering the city before the gates were closed, we resolved to wait

till the next morning and spend the night at Adelstaetten, a pretty

village about a league from Salzburg, and the last Bavarian post.

Night was falling as we approached a little wood which hid the

village from us. There we asked a peasant how far we had still to

go, and when he had answered our question he told us, evidently

with kind intention, that we should find good company in the

village, for a few hours earlier three journeymen laborers had

arrived there; and then he added that we should no doubt be glad to

meet comrades and have a gay evening with them. We were not

astonished to be taken for workmen, since every one who travels

here on foot, with a knapsack on his back, is understood to belong

to the laboring class. . .Arrived at the village, we were delighted

to find that the three journeymen were our traveling companions.

They had come, like ourselves, from Traunstein, where we had missed

each other in the crowd, and they were going likewise to sleep at

Adelstaetten, to avoid the custom-house. Finally, on Monday, at ten

o'clock, we crossed the long bridge over the Saala, between the

white coats with yellow trimmings on guard there. On the Bavarian

frontier we had hardly remembered that there was a custom-house,

and the name of student sufficed to pass us without our showing any

passports; here, on the contrary, it was another reason for the

strictest examination. "Have you no forbidden books?" was the first

question. By good fortune, before crossing the bridge, I had

advised Trettenbach to hide his song-book in the lining of his

boot. I am assured that had it been taken upon him he would not

have been allowed to pass. In ransacking Braun's bag, one of the

officials found a shell such as are gathered by the basketful on

the shores of the Lake of Neuchatel. His first impulse was to go to

the office and inquire whether we should not pay duty on this,

saying that it was no doubt for the fabrication of false pearls,

and we probably had plenty more. We had all the difficulty in the

world to make him understand that not fifty steps from the

custom-house the shores of the river were strewn with them. . .

After all this we had to empty our purses to show that we had money

enough for our journey, and that we should not be forced to beg in

order to get through. While we underwent this inquisition, another

officer made a tour of inspection around us, to observe our general

bearing, etc. . .After having kept us thus on coals for two hours

they gave us back our passports, and we went our way. At one

o'clock we arrived at Salzburg as hungry as wolves, but at the gate

we had still to wait and give up our passports again in exchange

for receipts, in virtue of which we could obtain permits from the

police to remain in the city. From our inn, we sent a waiter to get

these permits, but he presently returned with the news that we must

go in person to take them; there was, however, no hurry; it would

do in three or four hours! We had no farther difficulty except that

it was made a condition of our stay that we should not appear in

student's dress. This dress, they said, was forbidden in Austria.

They begged More to have his hair cut, otherwise it would be

shortened gratis, and also informed us that at our age it was not

becoming to dispense with cravats. Happily, I had two with me, and

Braun tied his handkerchief around his neck. It astonished me,

also, to see that we were not entered on the list of strangers

published every evening. So it was also, as we found, with other

students, though the persons who came with them by the same

conveyance, even the children, were duly inscribed. It seems this

is a precaution against any gathering of students. . .

The letter concludes in haste for the mail, and if the story of the

journey was finished the final chapter has not been preserved. Some

extracts from the home letters of Agassiz's friend Braun, which are

in place here, throw light on their university life for the coming

year.* (* See "Life of Alexander Braun", by his daughter, Madame

Cecile Mettenius.)

ALEXANDER BRAUN TO HIS FATHER.

MUNICH, November 18, 1828.

. . .I will tell you how we have laid out our time for this term.

Our human consciousness may be said to begin at half-past five

o'clock in the morning. The hour from six to seven is appointed for

mathematics, namely, geometry and trigonometry. To this appointment

we are faithful, unless the professor oversleeps himself, or

Agassiz happens to have grown to his bed, an event which sometimes

occurs at the opening of the term. From seven to eight we do as we

like, including breakfast. Under Agassiz's new style of

housekeeping the coffee is made in a machine which is devoted

during the day to the soaking of all sorts of creatures for

skeletons, and in the evening again to the brewing of our tea. At

eight o'clock comes the clinical lecture of Ringseis. As Ringseis

is introducing an entirely new medical system this is not wholly

without general physiological and philosophical interest. At ten

o'clock Stahl lectures, five times a week, on mechanics as

preliminary to physics. These and also the succeeding lectures,

given only twice a week on the special natural history of

amphibians by Wagler, we all attend together. From twelve to one

o'clock we have nothing settled as yet, but we mean to take the

lectures of Dollinger, in single chapters, as, for instance, when

he comes to the organs of the senses. At one o'clock we go to

dinner, for which we have at last found a comfortable and regular

place, at a private house, after having dined everywhere and

anywhere, at prices from nine to twenty kreutzers. Here, for

thirteen kreutzers* (* About nine cents of our money.) each, in

company with a few others, mostly known to us, we are provided with

a good and neatly served meal. After dinner we go to Dr. Waltl,

with whom we study chemistry, using Gmelin's text-book, and are

shown the most important experiments. Next week we are to begin

entomology with Dr. Perty, from three to four, three times a week.

From one to two o'clock on Saturday we have a lesson in

experimental physiology, plainly speaking, in animal dissection,

from Dr. Oesterreicher, a young Docent, who has written on the

circulation of the blood. As Agassiz dissects a great many animals,

especially fishes, at the house, we are making rapid progress in

comparative anatomy. At four o'clock we go usually once a week to

hear Oken on "Natur-philosophie" (a course we attended last term

also), but by that means we secure a good seat for Schelling's

lecture immediately after. A man can hardly hear twice in his life

a course of lectures so powerful as those Schelling is now giving

on the philosophy of revelation. This will sound strangely to you,

because, till now, men have not believed that revelation could be a

subject for philosophical treatment; to some it has seemed too

sacred; to others too irrational. . .This lecture brings us to six

o'clock, when the public courses are at an end: we go home, and now

begin the private lectures. Sometimes Agassiz tries to beat French

rules and constructions into our brains, or we have a lesson in

anatomy, or I read general natural history aloud to William

Schimper. By and by I shall review the natural history of grasses

and ferns, two families of which I made a special study last

summer. Twice a week Karl Schimper lectures to us on the morphology

of plants; a very interesting course on a subject but little known.

He has twelve listeners. Agassiz is also to give us lectures

occasionally on Sundays upon the natural history of fishes. You see

there is enough to do. . .

Somewhat before this, early in 1828, Agassiz had made the

acquaintance of Mr. Joseph Dinkel, an artist. A day spent together

in the country, in order that Mr. Dinkel might draw a brilliantly

colored trout from life, under the immediate direction of the young

naturalist, led to a relation which continued uninterruptedly for

many years. Mr. Dinkel afterward accompanied Agassiz, as his

artist, on repeated journeys, being constantly employed in making

illustrations for the "Poissons Fossiles" and the "Poissons d'Eau

Douce," as well as for his monographs and smaller papers. The two

larger works, the latter of which remained unfinished, were even

now in embryo. Not only was Mr. Dinkel at work upon the plates for

the Fresh-Water Fishes, but Mr. J.C. Weber, who was then engaged in

making, under Agassiz's direction, the illustrations for the Spix

Fishes, was also giving his spare hours to the same objects. Mr.

Dinkel says of Agassiz's student life at this time:--* (* Extract

from notes written out in English by Mr. Dinkel after the death of

Agassiz and sent to me. The English, though a little foreign, is so

expressive that it would lose by any attempt to change it, and the

writer will excuse me for inserting his vivid sketch just as it

stands.--E.C.A.)

"I soon found myself engaged four or five hours almost daily in

painting for him fresh-water fishes from the life, while he was at

my side, sometimes writing out his descriptions, sometimes

directing me. . .He never lost his temper, though often under great

trial; he remained self-possessed and did everything calmly, having

a friendly smile for every one and a helping hand for those who

were in need. He was at that time scarcely twenty years old, and

was already the most prominent among the students at Munich. They

loved him, and had a high consideration for him. I had seen him at

the Swiss students' club several times, and had observed him among

the JOLLY students; he liked merry society, but he himself was in

general reserved and never noisy. He picked out the gifted and

highly-learned students, and would not waste his time in ordinary

conversation. Often, when he saw a number of students going off on

some empty pleasure-trip, he said to me, 'There they go with the

other fellows; their motto is, "Ich gehe mit den andern." I will go

my own way, Mr. Dinkel,--and not alone: I will be a leader of

others.' In all his doings there was an ease and calm which was

remarkable. His studio was a perfect German student's room. It was

large, with several wide windows; the furniture consisted of a

couch and about half a dozen chairs, beside some tables for the use

of his artists and himself. Dr. Alex Braun and Dr. Schimper lodged

in the same house, and seemed to me to share his studio. Being

botanists, they, too, brought home what they collected in their

excursions, and all this found a place in the atelier, on the

couch, on the seats, on the floors. Books filled the chairs, one

alone being left for the other artist, while I occupied a standing

desk with my drawing. No visitor could sit down, and sometimes

there was little room to stand or move about. The walls were white,

and diagrams were drawn on them, to which, by and by, we artists

added skeletons and caricatures. In short, it was quite original. I

was some time there before I could discover the real names of his

friends: each had a nickname,--Molluscus, Cyprinus, Rhubarb, etc."

From this glimpse into "The Little Academy" we return to the thread

of the home letters, learning from the next one that Agassiz's

private collections were assuming rather formidable proportions

when considered as part of the household furniture. Brought

together in various ways, partly by himself, partly in exchange for

duplicates, partly as pay for arranging specimens in the Munich

Museum, they had already acquired, when compared with his small

means, a considerable pecuniary value, and a far higher scientific

importance. They included fishes, some rare mammalia, reptiles,

shells, birds, an herbarium of some three thousand species of

plants collected by himself, and a small cabinet of minerals. After

enumerating them in a letter to his parents he continues: "You can

imagine that all these things are in my way now that I cannot

attend to them, and that for want of room and care they are piled

up and in danger of spoiling. You see by my list that the whole

collection is valued at two hundred louis; and this is so low an

estimate that even those who sell objects of natural history would

not hesitate to take them at that price. You will therefore easily

understand how anxious I am to keep them intact. Can you not find

me a place where they might be spread out? I have thought that

perhaps my uncle in Neuchatel would have the kindness to let some

large shelves be put up in the little upper room of his house in

Cudrefin, where, far from being an annoyance or causing any smell,

my collection, if placed in a case under glass, or disposed in some

other suitable manner, would be an ornament. Be so kind as to

propose it to him, and if he consents I will then tell you what I

shall need for its arrangement. Remember that on this depends, in

great part, the preservation of my specimens, and answer as soon as

possible."

Agassiz was now hurrying forward both his preparation for his

degree and the completion of his Brazilian Fishes, in the hope of

at last fulfilling his longing for a journey of exploration. This

hope is revealed in his next home letter. The letter is a long one,

and the first half is omitted since it concerns only the

arrangements for his collections, the care to be taken of them,

etc.

TO HIS FATHER.

MUNICH, February 14, 1829.

. . .But now I must talk to you of more important things, not of

what I possess, but of what I am to be. Let me first recall one or

two points touched upon before in our correspondence, which should

now be fully discussed.

1st. You remember that when I first left Switzerland I promised you

to win the title of Doctor in two years, and to be prepared (after

having completed my studies in Paris) to pass my examination before

the "Conseil de Sante," and begin practice.

2nd. You will not have forgotten either that you exacted this only

that I might have a profession, and that you promised, should I be

able to make my way in the career of letters and natural history,

you would not oppose my wishes. I am indeed aware that in the

latter case you see but one obstacle, that of absence from my

country and separation from all who are dear to me. But you know me

too well to think that I would voluntarily impose upon myself such

an exile. Let us see whether we cannot resolve these difficulties

to our mutual satisfaction, and consider what is the surest road to

the end I have proposed to myself ever since I began my medical

studies. Weigh all my reasons, for in this my peace of mind and my

future happiness are concerned. Examine my conduct with reference

to what I propose in every light, that of son and Vaudois citizen

included, and I feel sure you will concur in my views.

Here is my aim and the means by which I propose to carry it out. I

wish it may be said of Louis Agassiz that he was the first

naturalist of his time, a good citizen, and a good son, beloved of

those who knew him. I feel within myself the strength of a whole

generation to work toward this end, and I will reach it if the

means are not wanting. Let us see in what these means consist.

[Here follows the summing up of his reasons for preferring a

professorship of natural history to the practice of medicine, and

his intention of trying for a diploma as Doctor of Philosophy in

Germany.] But how obtain a professorship, you will say,--that is

the important point? I answer, the first step is to make myself a

European name, and for that I am on the right road. In the first

place my work on the fishes of Brazil, just about to appear, will

make me favorably known. I am sure it will be kindly received; for

at the General Assembly of German naturalists and medical men last

September, in Berlin, the part already finished and presented

before the Assembly was praised in a manner for which I was quite

unprepared. The professors also, to whom I was known, spoke of me

there in very favorable terms.

In the second place there are now preparing two expeditions of

natural history, one by M. de Humboldt, with whose reputation you

are surely familiar,--the same who spent several years in exploring

the equatorial regions of South America, in company with M.

Bonpland. He has been for some years at Berlin, and is now about to

start on a journey to the Ural Mountains, the Caucasus, and the

confines of the Caspian Sea. Braun, Schimper, and I have been

proposed to him as traveling companions by several of our

professors; but the application may come too late, for M. de

Humboldt decided upon this journey long ago, and has probably

already chosen the naturalists who are to accompany him. How happy

I should be to join this expedition to a country the climate of

which is by no means unhealthy, under the direction of a man so

generally esteemed, to whom the Emperor of Russia has promised help

and an escort at all times and under all circumstances. The second

expedition is to a country quite as salubrious, and which presents

no dangers whatever for travelers,--South America. It will be under

the direction of M. Ackermann, known as a distinguished

agriculturist and as Councilor of State to the Grand Duke of Baden.

I should prefer to go with Humboldt; but if I am too late, I feel

very sure of being able to join the second expedition. So it

depends, you see, only on your consent. This journey is to last two

years, at the end of which time, happily at home once more, I can

follow with all desirable facilities the career I have chosen. If

there should be a place for me at Lausanne, which I should prefer

to any other locality, I could devote my life to teaching my young

countrymen, awaken in them the taste for science and observation so

much neglected among us, and thus be more useful to my canton than

I could be as a practitioner. These projects may not succeed; but

in the present state of things all the probabilities are favorable.

Therefore, I beg you to consider it seriously, to consult my uncle

in Lausanne, and to write me at once what you think. . .

In spite of the earnest desire for travel shown in this letter it

will be seen later how the restless aspirations of childhood,

boyhood, and youth, which were, after all, only a latent love of

research, crystallize into the concentrated purpose of the man who

could remain for months shut up in his study, leaving his

microscope only to eat and sleep,--a life as sedentary as ever was

lived by a closet student.

FROM HIS FATHER.

ORBE, February 23, 1829.

. . .It was not without deep emotion that we read your letter of

the 14th, and I easily understand that, anticipating its effect

upon us all, you have deferred writing as long as possible. Yet you

were wrong in so doing; had we known your projects earlier we might

have forestalled for you the choice of M. de Humboldt, whose

expedition seems to us preferable, in every respect, to that of M.

Ackermann. The first embraces a wider field, and concerns the

history of man rather than that of animals; the latter is confined

to an excursion along the sea-board, where there would be, no

doubt, a rich harvest for science, but much less for philosophy.

However that may be, your father and mother, while they grieve for

the day that will separate them from their oldest son, will offer

no obstacles to his projects, but pray God to bless them. . .

The subjoined letter of about the same date from Alexander Braun to

his father tells us how the projects so ardently urged upon his

parents by Agassiz, and so affectionately accepted by them, first

took form in the minds of the friends.

BRAUN TO HIS FATHER.

MUNICH, February 15, 1829.

. . .Last Thursday we were at Oken's. There was interesting talk on

all sorts of subjects, bringing us gradually to the Ural and then

to Humboldt's journey, and finally Oken asked if we would not like

to go with Humboldt. To this we gave warm assent, and told him that

if he could bring it about we would be ready to start at a day's

notice, and Agassiz added, eagerly, "Yes,--and if there were any

hope that he would take us, a word from you would have more weight

than anything." Oken's answer gave us but cold comfort;

nevertheless, he promised to write at once to Humboldt in our

behalf. With this, we went home in great glee; it was very late and

a bright moonlight night. Agassiz rolled himself in the snow for

joy, and we agreed that however little hope there might be of our

joining the expedition, still the fact that Humboldt would hear of

us in this way was worth something, even if it were only that we

might be able to say to him one of these days, "We are the fellows

whose company you rejected."

With this hope the friends were obliged to content themselves, for

after a few weeks of alternate encouragement and despondency their

bright vision faded. Oken fulfilled his promise and wrote to

Humboldt, recommending them most warmly. Humboldt answered that his

plans were conclusively settled, and that he had chosen the only

assistants who were to accompany him,--Ehrenberg and Rose.

In connection with this frustrated plan is here given the rough

draft of a letter from Agassiz to Cuvier, written evidently at a

somewhat earlier date. Although a mere fragment, it is the

outpouring of the same passionate desire for a purely scientific

life, and shows that the opportunity suggested by Humboldt's

journey had only given a definite aim to projects already full

grown. From the contents it must have been written in 1828. After

some account of his early studies, which would be mere repetition

here, he goes on: "Before finishing my letter, allow me to ask some

advice from you, whom I revere as a father, and whose works have

been till now my only guide. Five years ago I was sent to the

medical school at Zurich. After the first few lectures there in

anatomy and zoology I could think of nothing but skeletons. In a

short time I had learned to dissect, and had made for myself a

small collection of skulls of animals from different classes. I

passed two years in Zurich, studying whatever I could find in the

Museum, and dissecting all the animals I could procure. I even sent

to Berlin at this time for a monkey in spirits of wine, that I

might compare the nervous system with that of man. I spent all the

little means I had in order to see and learn as much as possible.

Then I persuaded my father to let me go to Heidelberg, where for a

year I followed Tiedemann's courses in human anatomy. I passed

almost the whole winter in the anatomical laboratory. The following

summer I attended the lectures of Leuckart on zoology, and those of

Bronn on fossils. When at Zurich, the longing to travel some day as

a naturalist had taken possession of me, and at Heidelberg this

desire only increased. My frequent visits to the Museum at

Frankfort, and what I heard there concerning M. Ruppell himself,

strengthened my purpose even more than all I had previously read. I

was, as it were, Ruppell's traveling companion: the activity, the

difficulties to be overcome, all were present to me as I looked

upon the treasures he had brought together from the deserts of

Africa. The vision of difficulty thus vanquished, and of the inward

satisfaction arising from it, tended to give all my studies a

direction in keeping with my projects."
