PREFACE.

The project of the American Journal of Science and Arts was first

suggested by Col. Gibbs, in November, 1817, during an accidental

interview on board the steamboat Fulton in Long Island Sound.[A] The

American Mineralogical Journal, by the late Dr. Archibald Bruce, (our

earliest purely scientific journal,) which had been begun a few years

before, was most favorably received both at home and abroad, but it

never passed beyond one volume of 270 pages; and as the declining

health of Dr. Bruce rendered the prospect of its continuance hopeless,

it was thought that we ought not to lose the advantage already gained,

and that a high demand of duty required that some man devoted to

science, should undertake to sustain its interests and those of the

connected arts, in our rising country. Although a different selection

of an editor would have been much preferred, and many reasons, public

and personal, concurred to produce diffidence of success, the arguments

of Col. Gibbs, whose views on subjects of science were entitled to

the most respectful consideration, and had justly great weight,

being pressed with zeal and ability, induced a reluctant assent;

and accordingly, after due consultation with many competent judges,

the proposals were issued early in 1818, embracing the whole range

of physical science and its applications. The Editor in entering on

the duty, regarded it as an affair for life, and the thirty years of

experience which he has now had, have proved that his views of the

exigencies of the service were not erroneous.

This Journal first appeared in July, 1818, and in June, 1819, the

first volume of four numbers and 448 pages was completed. This scale

of publication, originally deemed sufficient, was found inadequate to

receive all the communications, and as the receipts proved insufficient

to sustain the expenses, the work, having but three hundred and fifty

subscribers, was, at the end of the year, abandoned by the publishers.

An unprofitable enterprise not being attractive to the trade, ten

months elapsed before another arrangement could be carried into

effect, and therefore No. 1 of Vol. ii was not published until April,

1820. The new arrangement was one of mutual responsibility for the

expenses, but the Editor was constrained nevertheless to pledge his

own personal credit to obtain from a bank the funds necessary to begin

again, and from this responsibility he was, for a series of years,

seldom released. The single volume per annum being found insufficient

for the communications, two volumes a year were afterwards published,

commencing with the second volume.

At the conclusion of Vol. x, in February, 1826, the work was again

left upon the hands of its Editor; all its receipts had been absorbed

by the expenses, and it became necessary now to pay a heavy sum to

the retiring publisher, as an equivalent for his copies of previous

volumes, as it was deemed necessary either to control the work entirely

or to abandon it. The Editor was not willing to think of the latter,

especially as he was encouraged by public approbation, and was cheered

onward in his labors by eminent men both at home and abroad, and he saw

distinctly that the Journal was rendering service not only to science

and the arts, but to the reputation of his country. He reflected

moreover that in almost every valuable enterprise perseverance in

effort is necessary to success. He being now sole proprietor, a new

arrangement was made for a single year, the publishers being at

liberty, at the end of that time, to retire, and the Editor to resume

the Journal should he prefer that course.

The latter alternative he adopted, taking upon himself the entire

concern, including both the business and the editorial duties, and of

course, all the correspondence and accounts. From that time the work

has proceeded without interruption, two volumes per annum having been

published for the last twenty years; and its pecuniary claims ceased to

be onerous, although its means have never been large.

Forty-nine volumes having been published, ending with Number 100,

October, 1845, it was deemed expedient to close the series with a

fiftieth volume, which should contain an ample and well digested INDEX

of the whole. This great labor, vastly more arduous and protracted than

had been anticipated, is at last accomplished. The strict verification

of every reference in this Index, by actual comparison of the proof

with the volume and page, has been a labor surpassed only by the

toil of constructing the Index itself. The printing was commenced

in October, 1846, and so toilsome and time-consuming has been the

correction of the proofs, that although the work has gone steadily

forward, without interruption, it is only at this late day completed.

We may confidently believe that the volume will prove useful, not

only to those who may possess the whole series, but to all who are

connected in any way with the arts or sciences; for, whatever the

department, the reader is directed by it to the various memoirs that

have been published in the Journal on the subject that interests him,

whether relating to the progress of science, to details of facts in the

different departments of knowledge, or to the various resources of this

and other countries: with such a guide, the entire copies of the work

in public libraries or in those of individuals, become available.

As this volume may be consulted by many who have never seen the plan

and prospectus of the Journal with which the first volume began, we

republish, on this occasion, both the "Plan of the Work," and also

those parts of the "Introductory Remarks" in which our early views

were explained. Our readers will thus be able to judge how far we have

fulfilled our engagements, and also how far our prospective views have

been realized in the course of our now long experience. They will have

moreover before them in this Prospectus of 1817, the principles that

are still to guide us in our continued editorial labors.

"PLAN OF THE WORK.[B]

"This Journal is intended to embrace the circle of the PHYSICAL

SCIENCES, with their applications to the ARTS, and to every useful

purpose.

It is designed as a deposit for original American communications;

but will contain also occasional selections from Foreign Journals,

and notices of the progress of Science in other countries.

Within its plan are embraced,

NATURAL HISTORY, in its three great departments of MINERALOGY,

BOTANY and ZOOLOGY:--

CHEMISTRY and NATURAL PHILOSOPHY, in their various branches; and

MATHEMATICS, pure and mixed.

It will be a leading object to illustrate AMERICAN NATURAL HISTORY,

and especially our MINERALOGY and GEOLOGY.

The APPLICATIONS of these sciences are obviously as numerous as

physical arts and physical wants; for no one of these arts or wants

can be named which is not connected with them.

While SCIENCE will be cherished _for its own sake_, and with a due

respect for its own inherent dignity; it will also be employed as

the handmaid to the Arts. Its numerous applications to AGRICULTURE,

the earliest and most important of them; to our MANUFACTURES both

mechanical and chemical; and to our DOMESTIC ECONOMY, will be

carefully sought out, and faithfully made.

It is also within the design of this Journal to receive

communications on MUSIC, SCULPTURE, ENGRAVING, PAINTING, and

generally on the fine and liberal, as well as useful arts:--

On Military and Civil Engineering, and the art of Navigation:--

Notices, Reviews and Analyses of new scientific works, and of new

Inventions, and Specifications of Patents:--

Bibliographical and Obituary Notices of scientific men; essays on

Comparative Anatomy and Physiology, and generally on such other

branches of medicine as depend on scientific principles:--

Meteorological Registers, and Reports of Agricultural Experiments:

and we would leave room also for interesting miscellaneous things,

not exactly included under either of the above heads.

Communications are respectfully solicited from men of science, and

from men versed in the practical arts.

Learned Societies are invited to make this Journal, occasionally,

the vehicle of their communications to the public.

The Editor will not hold himself responsible for the sentiments and

opinions advanced by his correspondents; but he will consider it as

an allowed liberty to make slight verbal alterations, where errors

may be presumed to have arisen from inadvertency."

"INTRODUCTORY REMARKS.

"The age in which we live is not less distinguished by a vigorous

and successful cultivation of physical science, than by its

numerous and important applications to the practical arts, and to

the common purposes of life.

"In every enlightened country, men illustrious for talent, worth,

and knowledge, are ardently engaged in enlarging the boundaries of

natural science; and the history of their labors and discoveries is

communicated to the world chiefly through the medium of Scientific

Journals. The utility of such Journals has thus become generally

evident; they are the heralds of science; they proclaim its toils

and its achievements; they demonstrate its intimate connexion

as well with the comfort, as with the intellectual and moral

improvement of our species; and they often procure for it enviable

honors and substantial rewards.

"In England, the interests of science have been, for a series of

years, greatly promoted by the excellent Journals of Tilloch and

Nicholson; and for the loss of the latter, the scientific world has

been fully compensated by Dr. Thomson's Annals of Philosophy, and

by the Journal of Science and the Arts, both published in London.

"In France, the Annales de Chimie et de Physique, the Journal des

Mines, the Journal de Physique, &c. have long enjoyed a high and

deserved reputation. Indeed, there are few countries in Europe

which do not produce some similar publication; not to mention the

transactions of learned societies and numerous medical journals.

"From these sources _our_ country reaps, and will long continue

to reap, an abundant harvest of information: and if the light of

science, as well as of day, springs from the east, we will welcome

the rays of both; nor should national pride induce us to reject so

rich an offering.

"But can we do nothing in return?

"In a general diffusion of useful information through the various

classes of society, in activity of intellect, and fertility of

resource and invention, producing a highly intelligent population,

we have no reason to shrink from a comparison with any country.

But the devoted cultivators of science in the United States,

are comparatively few; they are, however, rapidly increasing in

number. Among them are persons distinguished for their capacity

and attainments, and, notwithstanding the local feelings nourished

by our state sovereignties, and the rival claims of several of

our larger cities, there is evidently a predisposition towards a

concentration of effort, from which we may hope for the happiest

results, with regard to the advancement of both the science and

reputation of our country.

"Is it not, therefore, desirable to furnish some rallying point,

some object sufficiently interesting to be nurtured by common

efforts, and thus to become the basis of an enduring, common

interest? To produce these efforts, and to excite this interest,

nothing, perhaps, bids fairer than a SCIENTIFIC JOURNAL.

"No one, it is presumed, will doubt that a Journal devoted to

science, and embracing a sphere sufficiently extensive to allure

to its support the principal scientific men of our country, is

greatly needed; if cordially supported, it will be successful, and

if successful, it will be a great public benefit.

"Even a failure, in so good a cause, (unless it should arise from

incapacity or unfaithfulness,) cannot be regarded as dishonorable.

It may prove only that the attempt was _premature_, and that our

country is not yet ripe for such an undertaking; for _without the

efficient support of talent, knowledge_, and _money, it cannot long

proceed_. No editor can hope to carry forward such a work without

the active aid of scientific and practical men; but, at the same

time, the public have a right to expect that he will not be sparing

of his own labor, and that his work shall be generally marked by

the impress of his own hand. To this extent the editor cheerfully

acknowledges his obligations to the public; and it will be his

endeavor faithfully to redeem his pledge.

"Most of the periodical works of our country have been short-lived.

_This_, also, _may_ perish in its infancy; and if any degree

of confidence is cherished that it will attain a maturer age,

it is derived from the obvious and intrinsic importance of the

undertaking; from its being built upon permanent and momentous

national interests; from the evidence of a decided approbation

of the design, on the part of gentlemen of the first eminence,

obtained in the progress of an extensive correspondence; from

assurances of support, in the way of contributions, from men of

ability in many sections of the union; and from the existence of

_such a crisis_ in the affairs of this country and of the world, as

appears peculiarly auspicious to the success of every wise and good

undertaking.

"As regards the subjects of the contemplated work, it is not in

our power to do much in the department of the natural history of

this country. Our Zoology has been more fully investigated than our

mineralogy and botany; but neither department is in danger of being

exhausted. The interesting travels of Lewis and Clark have recently

brought to our knowledge several plants and animals before unknown.

Foreign naturalists are frequently exploring our territory; and,

for the most part, convey to Europe the fruits of their researches,

while but a small part of our own productions is examined and

described by Americans: certainly, this is little to our credit,

and still less to our advantage. Honorable exceptions to the truth

of this remark are furnished by the exertions of some gentlemen in

our principal cities, and in various other parts of the Union.

"Our botany, it is true, has been extensively and successfully

investigated; but this field is still _rich_, and rewards every

new research with some interesting discovery. Our mineralogy,

however, is a treasure but just opened. That both science and art

may expect much advantage from this source, is sufficiently evinced

by the success which has crowned the active efforts of a few

ardent cultivators of this science: several new species have been

added to it in this country; great numbers of American localities

of minerals discovered, and interesting additions made to our

materials, for the useful and ornamental arts.

"Mineralogy is most intimately connected with our arts, and

especially with agriculture. Such are the disguises worn by many

most useful mineral substances, that an unskilful observer is

liable to pass a thing by, as worthless, which, if better informed,

he would seize with avidity; and, still more frequently, a

worthless substance, clothed perhaps in a brilliant and attractive

exterior, excites hopes altogether delusive, and induces expense,

without a possibility of remuneration. A diffusion of correct

knowledge on this subject is the only adequate remedy for either

evil.

"Our geology, also, presents a most interesting field of inquiry.

A grand outline has recently been drawn by Mr. Maclure, with a

masterly hand, and with a vast extent of personal observation and

labor: but to fill up the detail, both observation and labor still

more extensive are demanded; nor can the object be effected till

more good geologists are formed, and distributed over our extensive

territory.

"To account for the formation and changes of our globe, by

excursions of the imagination, often splendid and imposing, but

usually visionary, and almost always baseless, was, till within

half a century, the business of geological speculations; but this

research has now assumed a more sober character; the science of

geology has been reared upon numerous and accurate observations

of _facts_; and standing thus upon the basis of induction, it

is entitled to a rank among those sciences which Lord Bacon's

Philosophy has contributed to create.

"The outlines of American geology appear to be particularly grand,

simple, and instructive; and a knowledge of the important facts,

and general principles of this science, is of vast practical use,

as regards the interests of agriculture, and the research for

useful minerals. Geological and mineralogical descriptions, and

maps of particular states and districts, are very much needed in

the United States; and to excite a spirit to furnish them will form

one leading object of the contemplated journal.

"The science of natural philosophy, with its powerful auxiliary

mathematics, and the science of chemistry, the twin sister of

natural philosophy, are of incalculable importance to this country.

A volume would not suffice to trace their applications, and to

enumerate the instances of their utility.

"As one which may be allowed to stand, _instar omnium_, we may

mention the steam engine; that legitimate child of physical and

chemical science--at once more powerful than the united force

of the strongest and largest animals, and more manageable than

the smallest and gentlest; raising from the bowels of the earth

the massy treasures of its mines, drawing up rivers from their

channels, and pouring them, in streams of life, into the bosom

of cities; and, above all, propelling against the currents, the

winds, and the waves, of the ocean, those stupendous vessels, which

combine speed with certainty, and establish upon the bosom of the

deep the luxuries and accommodations of the land.

"The successful execution of this magnificent design was first

effected by Fulton and witnessed upon the waters of the Hudson, but

is now imitated in almost every civilized country; and it remains

to be seen whether steam will be applied in war.

"The mechanical inventions of this country are numerous; many of

them are ingenious, and some are highly important. In no way can

a knowledge of them be so readily and extensively diffused as in

a scientific journal. To this object, therefore, a part of our

labors (should there be a call for it) will be devoted, and every

necessary aid will be given by plates and descriptions.

"Science and art mutually assist each other; the arts furnish facts

and materials to science, and science illuminates the path of the

arts.

"Geometry, and mathematics both pure and mixed, can never cease

to be interesting and important to man, as long as the relations

of quantity shall exist, as long as ships shall traverse the

ocean, as long as man shall measure the surface or heights of the

earth on which he lives, or calculate the distances and examine

the relations of the planets and stars; and as long as the iron

reign of war shall demand the discharge of projectiles, or the

construction of complicated defenses.

"In a word, the whole circle of physical science is directly

applicable to human wants, and constantly holds out a light to the

practical arts; it thus polishes and benefits society, and every

where demonstrates both supreme intelligence, and harmony and

beneficence of design in the CREATOR."

Such was the pledge which, on entering upon our editorial labors in

1818, we gave to the public, and such were the views which we then

entertained, regarding science and the arts as connected with the

interests and honor of our country and of mankind. In the retrospect,

we realize a sober but grateful feeling of satisfaction, in having, to

the extent of our power, discharged these self-imposed obligations;

this feeling is chastened also by a deep sense of gratitude, first,

to God for life and power continued for so high a purpose; and next,

to our noble band of contributors, whose labors are recorded in half

a century of volumes, and in more than a quarter of a century of

years. We need not conceal our conviction, that the views expressed in

these "Introductory Remarks," have been fully sustained by our fellow

laborers.

Should we appear to take higher ground than becomes us, we find our

vindication in the fact, that we have heralded chiefly the doings

and the fame of others. The work has indeed borne throughout "the

impress" of editorial unity of design, and much that has flowed from

one pen, and not a little from the pens of others, has been without

a name. The materials for the pile, have however been selected and

brought in, chiefly by other hands, and if the monument which has

been reared should prove to be "_ære perennius_," the honor is not

the sole property of the architect; those who have quarried, hewn and

polished the granite and the marble, are fully entitled to the enduring

record of their names already deeply cut into the massy blocks, which

themselves have furnished.

If a retrospective survey of the labors of thirty years, on this

occasion, has rekindled a degree of enthusiasm, it is the natural

result of an examination of all our volumes, from the contents of which

we have endeavored to make out a summary both of the laborers and their

works.

We find that there have been about 600 contributors of original matter

to the Journal, and we have the unexpected satisfaction of believing

that probably five-sixths of them are still living; for we are not

certain that more than fifty are among the dead; of perhaps fifty more

we are without information, and if that additional number is to be

enrolled among the "stelligeri," we have still 500 remaining. Among

them are not a few of the veterans with whom we began our career,

and several of these are still active contributors. Shall we then

conclude that the peaceful pursuits of knowledge are favorable to long

life? This we think is, _cæteris paribus_, certainly true: but in the

present instance, another reason can be assigned for the large amount

of survivorship. As the Journal has advanced and death has removed

its scientific contributors, younger men and men still younger, have

recruited the ranks, and volunteers have enlisted in numbers constantly

increasing, so that the flower of the host are now in the morning and

meridian of life.

We have been constantly advancing, like a traveller from the

equinoctial towards the colder zones,--as we have increased our

latitude, stars have set and new stars have risen, while a few

planetary orbs visible in every zone, have continued to cheer us on our

course.

The number of articles, almost exclusively original, contained in the

Journal is about 1800, and the Index will show how many have been

contributed by each individual; we have doubtless included in this

number _some few_ articles republished from foreign Journals--but

we think they are even more than counterbalanced by original

communications without a name and by editorial articles, both of which

have been generally omitted in the enumeration.

Of smaller articles and notices in the Miscellany, we have not made

any enumeration, but they evidently are more numerous than the regular

articles, and we presume that they may amount to at least 2500.

Of party, either in politics or religion, there is no trace in our

work; of personalities there are none, except those that relate

to priority of claims or other rights of individuals. Of these

vindications the number is not great, and we could heartily have wished

that there had been no occasion for any.

* * * * *

During twenty years from the inception of this Journal, the editor

labored alone, although overtures for editorial coöperation had been

made to him by gentlemen commanding his confidence and esteem, and

who would personally have been very acceptable. It was, however, his

opinion that the unity of purpose and action so essential to the

success of such a work were best secured by _individuality_; but he

made every effort, and not without success, to conciliate the good

will and to secure the assistance of gentlemen eminent in particular

departments of knowledge. On the title page of No. 1, Vol. xxxiv,

published in July, 1838, a new name is introduced: the individual to

whom it belongs having been for several years more or less concerned

in the management of the Journal, and from his education, position,

pursuits and taste, as well as from affinity, being almost identified

with the editor, he seemed to be quite a natural ally, and his adoption

into the editorship was scarcely a violation of individual unity. His

assistance has proved to be very important:--his near relation to the

senior editor prevents him from saying more, while justice does not

permit him to say less.

It may be interesting to our readers to know something of the patronage

of the Journal. It has never reached one thousand paying subscribers,

and has rarely exceeded seven or eight hundred--for many years it

fluctuated between six and seven hundred.

It has been far from paying a reasonable editorial compensation; often

it has paid nothing, and at present it does little more than pay its

bills. The number of engravings and the extra labor in printer's

composition, cause it to be an expensive work, while its patronage is

limited.

It has a large gratuitous distribution, both at home and abroad, and

an extensive good-will exchange with works often having no particular

bearing upon its peculiar objects. It has incurred a heavy extra

expenditure in reprinting exhausted numbers, for the purpose of

furnishing entire sets of the work. No application for an entire set

has ever yet been disappointed, and complete sets of the volumes are

to be found in many institutions and in the hands of many individuals,

both in Europe and in the United States. Entire sets have often been

presented gratuitously to our infant colleges and to scientific

institutions and distinguished individuals in Europe. A few remain on

hand, and it is our intention to furnish them as long as we can afford

to republish, or can repurchase numbers that have run out.

* * * * *

The series of volumes must ever form a work of permanent interest on

account of its exhibiting the progress of American science during the

long period which it covers. Comparing 1817[C] with 1847, we mark on

this subject a very gratifying change. The cultivators of science in

the United States were then few--now they are numerous. Societies

and associations of various names, for the cultivation of natural

history, have been instituted in very many of our cities and towns,

and several of them have been active and efficient in making original

observations and forming collections. The American Philosophical

Society at Philadelphia, the American Academy of Arts and Sciences

at Boston, and the Academy of Natural Sciences also at Philadelphia,

numbered distinguished names among their members, and had published

valuable volumes of Transactions before our publication began. The

Connecticut Academy of Arts and Sciences had also published a single

volume as early as 1813. Since that time the Lyceum of Natural History

of New York, the Boston Society of Natural History, the Albany

Institute, and the Maryland Academy of Sciences have stood prominent

among associations of a like nature, and their memoirs now constitute

an important item in our scientific history. Other associations for the

departments of history and ethnography have also published memoirs;

and we must not omit to mention the American Geological Society, and

the Geological Society of Pennsylvania, which has issued one valuable

volume.

Of scientific collections we may say, that in the Institution from

which we date these remarks, going back only fourteen years from the

issuing of our first number, the entire mineralogical and geological

collection of the college was transported to Philadelphia in one small

box, and there, for lack of information elsewhere, the specimens were

named by the late Dr. Adam Seybert, then fresh from the celebrated

school of Werner at Freiburg in Germany, perhaps the only man then in

this country who could be regarded as a mineralogist scientifically

trained. Now, mineralogy and geology are familiar to our legislators

and our youth; and the institution which sent forth its little box

of unknown mineral treasures, unfolds to its pupils and the world a

magnificent collection not surpassed, if equalled, in the United States.

Boston, which at our earliest date presented only the limited

collection of the Linnæan Society, now opens to the student a rich

and beautiful museum of natural history; and Harvard University at

Cambridge has a fine botanical garden under an able and zealous

botanist--a well furnished and successful observatory, and a rich

collection of minerals and fossils, including a skeleton of the

Mastodon, which is rivalled only by the specimen of unexampled

magnitude and perfection, in the private museum of Dr. John C. Warren

in Boston.

Philadelphia may also boast of her cabinets of natural history, public

and private: and one of the noblest collections of birds in the

world,[D] bestowed on his country by Mr. Wilson of Delaware, has been,

within a few months, added to the valuable collections of the Academy

of Natural Sciences at that place.

When we began our Journal, not one of the States had been surveyed in

relation to its geology and natural history; now those that have not

been explored are few in number. State collections and a United States

Museum hold forth many allurements to the young naturalist, as well as

to the archæologist and the student of his own race. The late Exploring

Expedition with the National Institute, has enriched the capital

with treasures rarely equalled in any country, and the Smithsonian

Institution recently organized at Washington, is about to begin its

labors for the increase and diffusion of knowledge among men.

It must not be forgotten that the American Association of Geologists

and Naturalists--composed of individuals assembled from widely separate

portions of the Union--by the seven sessions which it has held, and by

its rich volume of reports, has produced a concentration and harmony

of effort which promise happy results, especially as, like the British

Association, it visits different towns and cities in its annual

progress.

Astronomy now lifts its exploring tubes from the observatories of many

of our institutions. Even the Ohio, which within the memory of the

oldest living men, rolled along its dark waters through interminable

forests, or received the stains of blood from deadly Indian warfare,

now beholds on one of its most beautiful hills, and near its splendid

city, a permanent observatory with a noble telescope sweeping the

heavens, by the hand of a zealous and gifted observer. At Washington

also, under the powerful patronage of the general government, an

excellent observatory has been established, and is furnished with

superior instruments, under the direction of a vigilant and well

instructed astronomer--seconded by able and zealous assistants.

Here also (in Yale College) successful observations have been made with

good instruments, although no permanent building has been erected for

an Observatory.

We only give single examples by way of illustration, for the history of

the progress of science in the United States, and of institutions for

its promotion, during the present generation, would demand a volume.

It is enough for our purpose that science is understood and valued,

and the right methods of prosecuting it are known, and the time is at

hand when its moral and intellectual uses will be as obvious as its

physical applications. Nor is it to be forgotten that we have awakened

an European interest in our researches: general science has been

illustrated by treasures of facts drawn from this country, and our

discoveries are eagerly sought for and published abroad.

While with our co-workers[E] in many parts of our broad land, we

rejoice in this auspicious change, we are far from arrogating it to

ourselves. Multiplied labors of many hands have produced the great

result. In the place which we have occupied, we have persevered despite

of all discouragements, and may, with our numerous coadjutors, claim

some share in the honors of the day. We do not say that our work might

not have been better done--but we may declare with truth that we have

done all in our power, and it is something to have excited many others

to effort and to have chronicled their deeds in our annals. Let those

that follow us labor with the like zeal and perseverance, and the

good cause will continue to advance and prosper. It is the cause of

truth--science is only embodied and systematized truth, and in the

beautiful conception of our noble Agassiz--"_it tells the thoughts of

God_."

* * * * *

Although we are writing a preface to our first series already closed,

we may, without impropriety, say something of the Second Series now in

successful progress. It began on the first of January, 1846; instead

of being quarterly like the First Series, it appears once in two

months--six times in a year, giving two volumes of 450 pages each.

In this Series, the name of a third editor appears upon the title

page, and the remarks which have been already made are, in their

spirit and almost in the letter, applicable in the present instance.

The _unity_ is still preserved, and both counsel and action--favored

by juxta-position and constant intercourse--are almost as if one

individual presided alone. It will be perceived, therefore, that we

have not departed from the principle which has governed us from the

beginning, and when our mantle shall fall, there are those at hand who

may, if it be worth the effort, arrest it in its descent and wear it

more worthily than we have done.

* * * * *

The portrait prefixed to this volume was engraved for a very different

purpose and for others than the patrons of this Journal. It has been

suggested by friends, whose judgment we are accustomed to respect, that

it ought to find a place here, since it is regarded as an authentic,

although, perhaps, a rather austere resemblance. In yielding to this

suggestion, it may be sufficient to quote the sentiment of Cowper on a

similar occasion, who remarked--"that after a man has, for many years,

turned his mind _inside out_ before the world, it is only affectation

to attempt to hide his face."

* * * * *

In tracing back the associations of many gone-by years, a host of

thoughts rush in, and pensive remembrance of the dead who have labored

with us casts deep shadows into the vista through which we view the

past.

Anticipation of the hour of discharge, when our summons shall arrive,

gives sobriety to thought and checks the confidence which health and

continued power to act might naturally inspire, were we not reproved,

almost every day, by the death of some coeval, co-worker, companion,

friend or patron. This very hour is saddened by such an event,--but

we will continue to labor on, and strive to be found at our post of

duty, until there is nothing more for us to do; trusting our hopes for

a future life in the hands of him who placed us in the midst of the

splendid garniture of this lower world, and who has made not less ample

provision for another and a better.

Yale College, April 19, 1847.

EXPLANATIONS.

Names of authors and subjects are arranged together alphabetically.

References to species of animals described or noticed in the Journal,

though to some extent distributed through the Index, are systematically

catalogued under the word _Zoology_. The same plan is followed

with _Botany_.

Obituary notices are collected together under _Obituary_.

The references under authors' names, when numerous, are sometimes

alphabetized, or distributed according to subjects, but often follow the

order of the volumes.

Works reviewed are mentioned under the names of their authors, and

also under the word _Works_.

When an article is illustrated by figures or plates, the fact is noted

by adding to the number of the page, the letter f.

A Supplement, is added, containing some omitted references.

The list of plates and wood cuts, is arranged according to volumes, and

the page or article is mentioned which each illustrates. The numbers in

this list indicate the proper order of succession in each volume, and

not the numbers that may appear on the plates.

[Footnote A: Vol. xxv, p. 215. Obituary notice of Col. Gibbs.]

[Footnote B: Taken from Vol. i, Am. Jour. Sci. and Arts, pp. v, vi;

also pp. 1 to 8, July, 1818.]

[Footnote C: The date of the incipient movements.]

[Footnote D: Late the _Rivoli_ collection of Paris.]

[Footnote E: Especially our ancient compeer, The Journal of the

Franklin Institute at Philadelphia.]
