Prof. F. R. Japp, in the Kekulé memorial lecture before the Chemical

Society of London, speaking of Kekulé's residence in that city,

September, 1897, said that he always acknowledged the influence which

Liebig and Odling and Williamson, with whom he became acquainted in

London, exercised on the formation of his opinions. Kekulé's theories,

Professor Japp said, were based on Gerhardt's type theory; on

Williamson's theory of polyvalent radicals, which by their power of

linking together other radicals render possible the existence of

multiple types; and Odling's theory of mixed types, which was a

deduction from Williamson's theory. Less consciously, perhaps, his

opinions were influenced by E. Frankland's theory of the valency of

elementary atoms, and by Kolbe's speculation on the constitution of

organic compounds. Kekulé gathered together the various ideas which he

found scattered throughout the writings of his predecessors, added to

them, and welded the whole into the consistent system which forms our

present theory of chemical structure. In 1857, in the course of a

memoir on the constitution of fulminic acid, he gave a tabular

arrangement of compounds formulated on the type of marsh gas, this

being the earliest statement, though put forward only in an imperfect

form, of the tetravalency of carbon. In the same year he published an

important theoretical paper On the So-called Conjugated Compounds and

the Theory of Polyatomic Radicals, which contains a complete system of

multiple types and mixed types. In 1858 the celebrated paper, On the

Constitution and Metamorphoses of Chemical Compounds, and on the

Chemical Nature of Carbon, appeared. It embodies the fully developed

doctrine of the tetravalency of carbon, together with Kekulé's views

on the linking of atoms and on the valency of such chains of atoms,

the foundation on which our modern system of constitutional chemistry

rests. In 1865 Kekulé put forward his well-known benzene

theory--pronounced by Professor Japp the crowning achievement, in his

hands, of the doctrine of the linking of atoms, and the most brilliant

piece of scientific prediction to be found in the whole range of

organic chemistry. The conception of closed chains, or cycloids, which

he thus introduced, has shown itself to be capable of boundless

expansion.

Kekulé's students all speak admiringly of his qualities as a teacher.

The memorialist of the German Chemical Society said: "All of us who

have attended his lectures or heard him in other places will ever

remember what a teacher Kekulé was. With incomparable lucidity and

sometimes with the happiest humor, he could go playfully through the

theme he was considering, masterfully presenting it in new and often

surprising aspects. The charm of his personality affected all who came

in contact with him; it was the geniality which shone out of his whole

being, and involuntarily commanded admiration. Numerous pupils flocked

to him, and many of those who to-day fill chairs of chemistry in

Germany and other countries have made his name highly honored."

Professor Thorpe, of London, who spent a little time in Kekulé's

laboratory, describes him as having been one of the very best

expositors, with the single possible exception of Kirchhoff, to whom

it had been his lot to listen. As a laboratory teacher he was

excellent. He was a most severe judge of work, striving to exact the

same high manipulative finish, the same neatness and order, which he

invariably bestowed on everything he did, and he was absolutely

intolerant of anything slovenly or "sloppy." "But it was as a lecturer

that he was seen at his best. He was singularly luminous as a thinker,

a close and accurate reasoner, with a remarkable power of concentrated

expression.... His language was apt and well chosen, and his delivery

easy and natural"; and his whole address showed that every detail had

been carefully considered.

At a distance of thirty years, Professor Dewar said, at the London

memorial meeting, that to look back and call to mind the presence and

personality of the great chemist as he knew him was indeed a pleasure.

He was a man of noble mien, handsome, dignified, and yet of a homely

and kindly disposition. He was a severe critic, having a haughty

contempt for the accidental and bizarre in scientific work. His

originality and suggestiveness seemed endless, so that he had no need

to commit trespass or to follow just in the wake of other people's

ideas. "Everything that passed through the Kekulé alembic was indeed

transmuted into pure gold. His precision of thought and diction

rendered his papers profoundly suggestive to other workers."

"The last years of the master's life," his German eulogist says, "were

often troubled by illness, but there were not wanting bright days

which the love of his students and colleagues prepared for him." Such

a one was the celebration of the twenty-fifth anniversary of his

professorship at Bonn, June 1, 1892, in which the students and

officers participated with cordial unanimity. The ceremony began in

the morning with an enthusiastic ovation by the students. The chemical

theater was decorated with plants; the benzene hexagon was figured on

the blackboard with garlands of flowers, in the midst of which the

letters A. K. were wrought in a monogram of roses. Alfred Helle, one

of the chemical students, delivered a felicitous address, in which he

congratulated his fellow-students on being privileged to sit at the

feet of the greatest of living chemists, after which three cheers were

given to the professor. Kekulé responded to the offering in an address

giving some of the details of his life, from which we have already

quoted. Kekulé's personal staff and the officers of the university

then presented their congratulations.

In the evening the students honored him with a torchlight procession,

it being the third time he had received this, the most conspicuous

honor which is bestowed by German students. The first occasion was in

1875, when he declined the professorship at Munich; the second was in

1878, when he was rector of the university, and was given in

celebration of the restoration of unity among the students, after a

long period of disunion. Among the torchbearers on that occasion was

the present Emperor of Germany.

During the later period of his life Kekulé was comparatively sterile.

Those who knew him, however, Professor Thorpe says, "would be the

first to affirm that this seeming apathy sprang from no natural

indifference. There is no doubt that he suffered, even in the early

period of middle life, from the intense stress and strain of his

mental labors prior to the Ghent period. He too surely exemplified the

sad truth of Liebig's saying that he who would become a great chemist

must pay for his pre-eminence by the sacrifice of his health. There is

reason to know that it was the consciousness of failing power which

prevented him from finishing much to which he had put his hand, and

that his fastidiousness and his sense of 'finish,' amounting almost to

hypercriticism, restrained him from publishing much which he realized

fell short of his ideal."

The last time Kekulé's name was brought before the public was on the

occasion of the renewal of the ancient title of nobility of his

family, as August Kekulé von Stradowitz.

Editor's Table.

_A VOICE FROM THE PULPIT._

We called attention last month to a weak attack on the doctrine of

evolution by a certain Mr. A. J. Smith, Superintendent of Public

Schools in the city of St. Paul. The only thing which gave any

consequence to the deliverance in question was that it was addressed

to a large gathering of public-school teachers, who might possibly

have been unduly influenced in their appreciation of it by the

speaker's official position. We are glad now to learn that, very

shortly after the publication of Superintendent Smith's address, an

excellent statement of the true relation of the doctrine of evolution

to education was made in one of the city pulpits by the Rev. S. G.

Smith, who did not boast, as the superintendent had done, of having

made an exhaustive study of the subject, but who, nevertheless, showed

that he had a grasp of it which the other altogether lacked. The Rev.

Mr. Smith's discourse would have merited attention wherever it might

have been delivered; but, considered as a pulpit utterance, it seems

to us to possess a special and very encouraging significance. We need

hardly say that the pulpit has not always been friendly to broad

scientific views, but in this case it has spoken with a candor, a

breadth, and an intelligence which the lecture platform can not do

more than equal, and which it would certainly be too much to look for

in all our colleges.

"The law of evolution," said the reverend gentleman, "is as universal

in its application as the law of gravitation. It holds that in every

realm the simple tends to become complex, and that the complex is more

stable than the simple. Motion and matter have a history in which the

simple and the indefinite take on variety of organization and

definiteness of adaptation." This is a statement in which the author

of the Synthetic Philosophy would probably have very little change to

suggest. Mr. Smith does not, like so many who discuss the subject in a

superficial manner, confound evolution with Darwinism. Darwinism, he

recognizes, may, in its particular explanations as to the origin of

species and the descent of life, be in error; but evolution is

universal in its scope, and can only fail if it can be shown that the

fundamental postulates on which it rests, such as the instability of

the homogeneous, the continuity of motion, the law of rhythm, etc.,

are not to be depended on. Must a person have made the circle of the

sciences and comprehended all knowledge before he can reasonably

profess a belief in evolution? No, says Mr. Smith; when the

foundations of a doctrine have been clearly laid, when they have been

tested by many different investigators from many different points of

view, and when these, almost without exception, affirm that the

doctrine is not only in harmony with, but lends a new and deeper

significance to, the several orders of fact with which they are

individually concerned, any person of ordinary intelligence is

justified in considering that doctrine as satisfactorily proved and

giving it his personal adhesion.

What chiefly excited the ire of Superintendent A. J. Smith was the

contention of evolutionists that the modern child reflects the earlier

stages of human development. He asked his audience if they really

thought the children of to-day were young savages, and quoted Emerson

and Longfellow as authorities on the question. The Rev. S. G. Smith

takes up the point and expresses himself as follows: "When it is

stated that the child has many points of contact with primitive man,

it is not meant that the child is a savage, but that 'in its

immaturity' we can learn much respecting it from the study of child

races. The child has neither the virtues nor the vices of the savage,

but he has many of the mental characteristics. Embryology does not

teach that in prenatal life the child passes into the form of every

animal in a menagerie, but that its life passes through the stages

that mark the great subdivisions of all life. Nor do the comparisons

of the child with primitive man imply that he must pass through all

the activities of savage races, but that the development of his

faculties, the tendencies of his desires, the state of his ignorance,

all illustrate the history of the development of the race. Primitive

man may be understood by a study of the child, and, conversely, the

child may be illustrated by primitive man."

It must be borne in mind that the child is in constant contact with

its elders, that it is subject to the restraints which they impose,

and that it lives more or less in an atmosphere of affection and care.

There is excellent reason, therefore, why it should not resemble

primitive man in all points. Its daily life is really controlled and

guided by a higher power. In some cases there is even too much control

and guidance; the conditions are made too artificial, and the

development of the child's nature suffers in consequence. When the age

of manhood or womanhood is reached there is something lacking,

precisely because enough scope was not left for the primitive or, as

we may very properly say, the "savage" instincts of childhood. A great

French writer, Joseph de Maistre, quotes a popular saying to the

effect that "spoilt children always turn out well."[49] So far as

there is any truth in it, the explanation is that the spoilt child is

one that has a great deal of its own way, and is left to work out the

savage and so acquire a sounder foundation for its future life. In how

many of us are there not chained savages that might have made their

escape in earlier years if they had only been allowed! It is a

dangerous thing to try to make little angels of children.

The Rev. Mr. Smith is quite right in what he says as to the

predominance of the imagination in children, this being another strong

point of resemblance to primitive man. "The beginnings of history and

institutions," he truly says, "can only be understood when we remember

that races in their early development do not have clearly marked

activities of imagination, reason, and memory. They mix the three. So

legends, myths, and heroics are earnest efforts of the undeveloped

mind to make objective the truth, and are not clumsy lies at all."

Applying this to the child, the conclusion is that "he must be fed

through his imagination or he will not grow." A very imaginative child

is apt to be accused of falsehood, when he simply fails to distinguish

between things imagined and things remembered. Neither the child nor

the savage can concentrate his attention, and to force either to do so

beyond a certain very limited measure is simply to injure and deform

such natural powers as he possesses. The amount of mischief which a

dogmatic and over-logical teacher, wholly ignorant of the psychology

of the child, can do is beyond all calculation.

It is needless, however, to pursue the parallel further, though the

Rev. Mr. Smith very properly carries it into the region of morals,

where it is no less close than in that of intellectual action. There

is another interesting aspect of evolution which the reverend

gentleman glances at, and that is its bearing on general courses of

study. History and literature, considered as departments of research,

it has largely transformed by substituting for conventional categories

and abstract notions the perception of a genetic process pervading all

the works of the human spirit and linking them into an organic unity.

In conclusion, we may observe that, if Superintendent A. J. Smith had

not made some foolish remarks in a rather ostentatious manner, it is

probable the Rev. S. G. Smith would not have delivered the excellent

discourse on which we have commented, and which we feel sure will far

outweigh in general effect the performance which called it forth. The

conclusions to be drawn are the pleasing ones that good may sometimes

come out of evil, and that a free pulpit is admirably adapted to guard

the interests of liberty and common sense.

_LESSONS OF ANTHROPOLOGY._

The address delivered at the last meeting of the British Association

by the president of the Anthropological Section contained nothing that

was strikingly novel--it is not every year that striking novelties can

be announced--but it dealt in an interesting manner with several

phases of a most important subject. The speaker, Professor Brabrook,

took the position that the order of the universe is expressed in

continuity, not cataclysm, and that this principle will be found

illustrated in every branch of anthropological research, in direct

proportion to the completeness of the data obtained. He admitted the

vastness of the gap which still separates the remains of palaeolithic

from those of neolithic man, but expressed the belief that further

explorations would bring intermediate relics to light. To quote the

speaker's words: "The evidence we want relates to events which took

place at so great a distance of time that we may well wait patiently

for it, assured that somewhere or other these missing links must have

existed, and probably are still to be found."

Reference was made to the labors which are now being usefully expended

in gathering what is called the folklore of various communities, and

to the result which continually appears with fuller evidence, namely,

that the tendency of mankind everywhere is to develop like fancies and

ideas at a like stage of intellectual development. Full of detail as

these stories are, they are found to contain but a few primitive

ideas; and it seems not improbable that to a large extent they are

essentially Nature myths. Mr. Brabrook happily quotes Lord Bacon's

description of such narratives as "sacred relics, gentle whispers and

the breath of better times." The "better times" are a part of the

general system of myth; but who will deny that there is a special

charm in these early documents of our race? "Let one of our literary

exquisites," said a thoughtful French writer, "try to write a fairy

tale which shall neither be a pretentious apologue nor a tiresome and

transparent allegory, and he will soon feel that mere cleverness does

not suffice to create these marvelous narratives, and will conceive a

just admiration for those who constructed them, that is to say,

everybody and nobody."

The progress of anthropology, according to the president of the

section, seems more and more to confirm the theory adopted by Fustel

de Coulanges in France and Spencer in England, that the belief in

spirits lies at the basis of all religious systems. We thus see, to

use his words, "that the group of theories and practices which

constitute the great province of man's emotions and mental operations

expressed in the term 'religion' has passed through the same stages,

and produced itself in the same way, from rude early beginnings, as

every other mental exertion." Mr. Brabrook mentions a work lately

published by "a distinguished missionary of the Evangelical Society of

Paris," the Rev. Mr. Coillard, in which an account is given of the

superstitions prevailing among the natives of the upper Zambesi. The

reverend gentleman tells of their belief in witchcraft, and gives a

story of a young woman who was condemned to penal labor on suspicion

of having bewitched, or tried to bewitch, another young woman who had

taken her husband from her; the evidence of the crime being found in a

dead mouse, which had been discovered in the second young woman's

chamber. The missionary says: "She was made a convict. A few years ago

she would have been burned alive. Ah, my friends, paganism is an

odious and a cruel thing!" On which the president of the

Anthropological Section observes: "Ah, Mr. Coillard, is it many years

ago that she would have been burned alive or drowned in Christian

England or Christian America? Surely the odiousness and the cruelty

are not special to paganism any more than to Christianity." This is

much to the point. If witchcraft is no longer a recognized crime in

England or America, it is not because these lands are Christian, but

because science is mixed with their Christianity. Even missionaries

ought to know this.

A great many different sciences are grouped under the name

"anthropology," but they all have their rallying point in man, whose

nature and history they seek to explore. The fact is that all sciences

should have the same rallying point; and we trust that the greater

interest which is visibly being taken year by year in anthropological

studies will tend to humanize in a beneficial degree the whole circle

of human knowledge.

_AN EXAMPLE OF SOCIAL DECADENCE._

That the incessant encroachment of the Government upon the rights of

the individual will produce social decadence is a truth that most

Americans have yet to learn. With a light heart they are constantly

approving scheme after scheme for social regeneration that involves

some restriction upon freedom, or an increase of taxation, or both. It

is not perhaps singular that the history of similar schemes in the

past should possess no lesson for them. When President Eliot, of

Harvard University, says that the experience of the Italian republics

has no value for us, it is not to be expected that persons with less

capacity to interpret the records of other times should attach little

or no importance to them. But they ought not most certainly to

maintain the same attitude toward the experience of the nations of

to-day. It is to blind their eyes to what does not rest upon hearsay

or upon dubious documents--to what admits of the clearest

demonstration at the hands of living witnesses.

For this reason we urge upon all students of social science the study

of the condition of the inhabitants of the black-earth region of

Russia. In that field, one of the largest and most fruitful in the

world for investigation, they will find the amplest evidence of the

frightful havoc wrought by the abridgment of individual freedom and

the seizure of private property in the form of taxes for public

purposes. If it be said that Russia is an autocracy, and can not

therefore furnish instruction to a democracy like the United States,

the answer is easy, if not obvious. Despotism, like gravitation, is

the same all over the world. It makes no difference in the long run

whether a law abridging freedom issues from the palace of a czar or

from the legislative halls of a popular assembly. The individual

objecting to it is obliged to regulate his life, not in accordance

with his own notions, but in accordance with the notions of some one

else. It makes no difference, either, whether taxation is imposed by

an imperial edict or by a legislative vote. The citizens that have to

bear it against their will contribute money for purposes that some one

else only approves of. The only difference between Russia and the

United States is that this kind of despotism has been carried to much

greater lengths in one country than in the other. If, therefore, we

can find out what the effect has been in Russia, we will be able to

predict what the effect will be in the United States.

As every person familiar with Russia knows, the black-earth region is

one of the richest and most productive in the world. It ought to be

inhabited by one of the wealthiest and happiest of peoples. Yet such

is not the case. According to Count Tolstoi, who contributed recently

a letter to the London Times on the subject, the inhabitants are among

the poorest and most miserable in the world. They are in a state of

chronic starvation. They are obliged to content themselves with nearly

a third less food than is sufficient to maintain normal health. The

physical effect of this insufficiency of food is a decrease in

vitality, a diminished stature, and a check to the growth of

population. It is proved, first, by the failure of the peasants of the

region to meet the requirements for military service, and, second, by

the statistics of population, which show that the increase of births

over deaths has fallen from the maximum reached twenty years ago to

zero.

But the mental effects of the destitution wrought by the robberies of

the Government are more distressing even than the physical. It gives

birth to a stolidity and despair that tend to paralyze all effort

toward betterment. The people subjected to it come to feel that there

is no use of making any struggle beyond the maintenance of mere

existence. Whatever they get in excess of this requirement will be

taken from them. "A peasant," says Tolstoi, illustrating this fact,

"feels that his position as an agriculturalist is bad, but he believes

that it can not be improved; and, consequently, adapting himself to

this hopeless position, he no longer fights against it, but lives and

acts only in so far as he is stirred by the instinct of

self-preservation. Moreover, the very wretchedness of his condition

increases still more his depression of spirit. The lower the economic

condition of a population sinks, like a weight on a lever, the more

difficult it becomes to raise it again; the peasants feel this, and,

as it were, throw away the helve after the hatchet. 'Why should we

trouble ourselves?' they say. 'We sha'n't get fat. If we can only keep

alive.'"

The fruits of this mental state are as palpable as those of the lack

of food. They are to be found in every direction. In manners, habits,

and customs the peasants are hopelessly conservative. They belong, not

to the nineteenth century, but to the ninth. Instead of adopting new

and improved methods of agriculture, they cling to those of the

subjects of Rurik. They use the old plow, distribute tillage in three

crops, and divide their fields into long, narrow strips. So slowly do

they toil with primitive implements and debilitated animals, and so

indifferent are they to what they are doing, that it takes them a day

to do the work that a well-fed and alert peasant would do in half the

time. A more deplorable sign of demoralization is the prevalence of

family discord and loss of interest in a higher life. The aggressions

of the state have stimulated selfishness, bad temper, and incipient

rebellion. The children disobey their parents, the younger brothers

reject the primacy of the older, and money earned elsewhere is kept

from the family treasury. With the decadence of family life there is a

decadence of religious life. Although the peasants are nominally

orthodox, they care nothing for religion. Even the clergy confirm the

fact that they are becoming more and more indifferent to the church.

What they seek is not to penetrate the mysteries of life, but to

obliterate consciousness of them. "Under these circumstances," says

Tolstoi, alluding to the economic and mental decadence, "the craving

for forgetfulness is natural, and accordingly spirits and tobacco are

being consumed in ever greater and greater quantities." He adds that

"even quite young boys drink and smoke."
