THE twenty-second meeting of the American Association for the Advancement of Science, which commenced at Portland, Me., August 20th, was fairly attended by the members, and presented very good results in the way of scientific work.



THE twenty-second meeting of the American Association for the Advancement of Science, which commenced at Portland, Me., August 20th, was fairly attended by the members, and presented very good results in the way of scientific work. In estimating its contributions, we must not overlook the fact that, while the numbers of thїose in this country who are at liberty to pursue original investigations untrammelled, is not large, on the other hand we have two national associations, through which the moderate amount of original research that takes place is published to the world. While the American Association was the only organization of national scope for the publication of new scientific results, its papers were creditable both in number and quality, and it compared favorably with its prototype, the British Association for the Advancement of Science. But, when, a few years ago, a considerable number of its ablest members joined in the organization of the National Academy of Sciences, having substantially the same object in view as the American Association, but exclusive in its membership, and under government patronage, the necessary effect was greatly to weaken the older organization. The National Academy meets twice a year, and draws closely upon the original work of its associates. If, therefore, the numbers in attendance upon the Association and the grade of scientific contributions might seem to indicate a decline in American science, the circumstances here referred to will sufficiently qualify the conclusion.

The address of the retiring president, J. Lawrence Smith, while containing many excellent suggestions, was not conformed to the better type of such productions. It is the custom of the eminent scientific men who are honored with the office but once in their lives to devote the occasion, either to a general review of recent scientific work, or to some special subject with which they are most familiar, and upon which they can speak with the force of authority. Dr. Smith has been favorably known in the world of science as a chemist who has made valuable contributions in its inorganic department. The great activity in chemical inquiries at the present time, and the important transition through which chemical theory is now passing, would certainly have afforded the president a most pertinent and instructive theme, but he preferred to employ the occasion in considering certain aspects of science that are now prominent in public attention, and upon which the scientific world is in much disagreement. The leading feature of the address was an attack on the Darwinians, and this portion of it we publish ; and, as the question is thus reopened officially, it becomes a proper subject of comment.

The predecessor of President Smith, Dr. Asa Gray, of Harvard College, had followed the better usage of presiding officers in his address at Dubuque last year, and discussed some of the larger problems of botany in the light of the derivation theory. The most eminent of American botanists, an old and untiring student of the subject, a man of philosophic grasp, and with a candor and sincerity of conviction that commanded the highest respect, after long and thorough study of the question, Prof. Gray did not hesitate to give the weight of his authority to that view of the origin and diversities of living forms of which Mr. Darwin is now the leading representative. And although in the field of biology large numbers of its most eminent students, who are of all men most competent to decide upon it, have accepted that doctrine as representing the truth of Nature more perfectly than any other, and as of immense value in their researches into the laws of life, yet Dr. Smith, as our readers will see, denounces it as a groundless hypothesis due to a riotous imagination, and, in the language of Agassiz, a “ mere mire of assertions.” His declarations have called forth the applause of the press—always so candid, and intelligent, and independent, on such matters—who seize the occasion to preach new sermons on the “ vagaries of science,” and declare that they “take sides with the angels against the monkeys,” and are “ with the Creator against Darwin.”

The course of the president was not commended even by his own party. Dr. Newberry, an eminent student of biology and geology, is reported as having spoken in the following decided way: “Prof. Newberry, after a handsome allusion to the retiring president, Prof. J. Lawrence Smith, protested against the opposition to the development theory as expounded in that gentleman’s address. Prof. Newberry said he was not himself a Darwinian, but he recognized the value of the evolution theory in science. You cannot measure its value as you can the work of an astronomer, measured by definite ratios of space and time ; but he considered the hypothesis one of the most important contributions ever made to a knowledge of Nature. Most men and women are partisans, and some are willing to suppose that the hypothesis is sufficient to account for all the phenomena of the animal kingdom, while, on the other hand, there are those who see in it nothing but failure and deficiency. Let us assume a judicial position, and allow the tests of time and truth to settle the questions involved. Go, however, in whatever direction the facts may lead, and throw prejudice to the winds. Becollect that all truth is consistent with itself.”

Dr. Smith can hardly be said to have argued the question of Darwinism. He gave us his own opinion of it, and quoted, to sustain it, two distinguished authorities in natural history. But he gave the influence of his name and position to the charge that it transcends the legitimate limits of inductive inquiry, and is only a wild and absurd speculation. "While the technical and difficult questions of natural history by which the truth or falsity of the doctrine must be determined are beyond the reach of unscientific readers, and belong to the biologists to decide, the question here raised as to whether the investigation, as conducted, is legitimately scientific or not, is one of which all intelligent persons ought to be capable of forming a judgment. We have repeatedly considered this point in the pages of THE POPTJLAE SCIENCE MONTHLY, and have endeavored to show that the present attitude of the doctrine of evolution is precisely the attitude which all the great established theories and laws of science had to take at their first promulgation. It is familiar to all who know any thing of the progress of science, that astronomy and geology, in their early stages, passed through precisely the same ordeal that biology is passing through now ; their leading doctrines were reprobated as false science, and the wild dreams of distempered imaginations. Let us now take another case, in the department of pure physics, and see how scientific history repeats itself :

The undulatory theory of light is now a firmly established principle in physics. Dr. Smith says that “the failure to explain one single well-observed fact is sufficient to cast doubt upon, or subvert, any pure hypothesis,” and, he adds, in reference to the undulatory theory, that, “ up to the present time, it serves in all cases.” In order that this theory, now so perfect, should be adopted, it had, of course, to be first propounded. The conception of an ethereal medium to explain the phenomena of light was suggested by Huyghens and Euler, but they did not experimentally demonstrate it, and their authority was overborne by that of Newton,who maintained the emission or corpuscular theory. The true founder of the undulatory hypothesis of light was Dr. Thomas Young, Professor of Natural Philosophy in the Royal Institution of Great Britain, and whom Prof. Tyndall regards as the greatest physicist who has appeared since Newton. Dr. Young is thus estimated by the German Helmholtz : “ His was one of the most profound minds that the world has ever seen ; but he had the misfortune to be in advance of his age. He excited the wonder of his contemporaries, who, however, were unable to follow him to the heights at which his daring intellect was accustomed to soar. His most important ideas lay, therefore, buried and forgotten in the folios of the Royal Society, until a new generation gradually and painfully made the same discoveries, and proved the exactness of his assertions, and the truth of his demonstrations.”

Now, in this case, there was no monkey in the question, and no capital of public prejudice that could be made available in the discussion, to repress obnoxious opinions. The hypothesis was certainly innocent enough, and its truth or falsehood was a matter of simple determination by experiment. Dr. Young made the experiments which established it—the Royal Society recognized the value of the experiments, and, in 1801, assigned to their author the distinguished honor of delivering the Bakerian lecture, in which his experiments were described, and their conclusions demonstrated. Yet, with the Royal Society to back him, and with his views capable of proof before all men, Dr. Young was crushed, and that by outside influences appealing to the public, on the ground that his hypothesis was spurious science—mere wild absurdity of the imagination.

"We ask attention to the similarity of the present ground of attack upon Darwin, and the ground of attack upon Dr. Young three-quarters of a century ago. Dr. Smith prefaces his strictures upon Darwinism with the following declaration : “ It is a very common attempt nowadays for scientists to transcend the limits of their legitimate studies, and, in doing this, they run into speculations apparently the most unphilosophical, wild, and absurd ; quitting the true basis of inductive philosophy, and building up the most curious theories on little else than assertion.”

Henry Brougham, afterward LordChancellor of England, writing in the second number of the Edinburgh Review concerning Young’s Bakerian lecture, said: “We have of late observed in the physical world a most unaccountable predilection for vague hypotheses daily gaining ground ; and we are mortified to see that the Royal Society, forgetful of those improvements in science to which it owes its origin, and neglecting the precepts of its most illustrious members, is now, by the publication of such papers, giving the countenance of its highest authority to dangerous relaxations in the principles of physical logic. We wish to raise our feeble voice against innovations that can have no other effect than to check the progress of science, and renew all those wild phantoms of the imagination which Bacon and Newton put to flight from her temple. . . . Has the Royal Society degraded its publications into bulletins of new and fashionable theories for the ladies of the Royal Institution ? Proh, pudor ! 1 Let the professor continue to amuse his audience with an endless variety of such harmless trifles, but, in the name of science, let them not find admittance into that venerable repository which contains the works of Newton and Boyle. . . . The making of an hypothesis is not the discovery of a truth. It is a mere sporting with the subject ; it is a sham-fight which may amuse in the moment of idleness and relaxation, but will neither gain victories over prejudice and error, nor extend the empire of science. A mere theory is in truth destitute of merit of every kind, except that of a warm and misguided imagination.” Dr. Young’s theory “ teaches no truth, reconciles no contradictions, arranges no anomal ©us facts, suggests no new experiments, and leads to no new inquiries. It has not even the pitiful merit of affording an agreeable play to the fancy. It is infinitely more useless, and less ingenious, than the Indian theory of the elephant and tortoise. It may be ranked in the same class with that stupid invention of metaphysical theology. ... We cannot conclude our review of these articles without entreating for a moment the attention of that illustrious body which has admitted of late years so many paltry and unsubstantial papers into its transactions. ... We implore the council, if they will deign to cast their eyes upon our humble page, to prevent a degradation of the institution which has so long held the first rank among scientific bodies.”

For shame 1

For the second time Dr. Young was selected by the Royal Society to give the Bakerian lecture, and he again chose for its subject “Experiments and Calculations relative to Physical Optics,” and again the Edinburgh Review came down upon him as follows : “ The paper which stands first is another Bakerian lecture, containing more fancies, more blunders, more unfounded hypotheses, more gratuitous fictions, all upon the same field on which Newton trode, and all from the fertile yet fruitless brain of the same eternal Dr. Young.” The reviewer thus winds up the controversy: “We now dismiss, for the present, the feeble lucubrations of this author, in which we have searched without success for some traces of learning, acuteness, and ingenuity, that might compensate his evident deficiency in the powers of solid thinking, calm and patient investigation, and successful development of the laws of Nature, by steady and modest observation of her operations. We came to the examination with no other prejudice than the very allowable prepossession against vague hypothesis, by which all true lovers of science have for above a century and a half been swayed. We pursued it, both on the present and on a former occasion, without any feelings except those of regret at the abuse of that time and opportunity which no greater share of talents than Dr. Young’s are sufficient to render fruitful by mere diligence and moderation. From us, however, he cannot claim any portion of respect, until he shall alter his mode of proceeding, or change the subject of his lucubrations; and we feel ourselves more particularly called upon to express our disapprobation, because, as distinction has been unwarily bestowed on his labors by the most illustrious of scientific bodies, it is the more necessary that a free protest should be recorded before the more humble tribunals of literature.”

The reader will perceive that this strain is not unfamiliar. Young was denounced as Darwin is now denounced, professedly in the interest of science; but the pretext was as false then as it is now. In the former case the animus of the assault was mere personal spite : Brougham’s inordinate vanity having been wounded by some very moderate criticisms of Dr. Young upon his mathematical works. But a man who did not understand the subject, appealing to a tribunal which knew nothing about it, against wild speculations degrading to science, was able to depreciate and suppress for a quarter of a century one of the most solid and perfect theories of natural phenomena that modern research lias produced. And, strange as it may seem, the work was effectually done ; for, although Young made a masterly reply, but a single copy was sold, and, as Tyndall remarks, “for twenty years this man of genius was quenched—hidden from the appreciative intellect of his countrymen — deemed, in fact, a dreamer through the vigorous sarcasm of a writer who had then possession of the public ear.”

Happily, the time is past when the investigators of Nature can be thus crushed out ; but still the old tactics are imitated, and not without evil effect for the time. The men of science, to whom the question belongs, are not left to pursue it in peace. The press and the pulpit, with such scientific help as it is not difficult to get, stir up such a clamor of popular opprobrium that biological students who hold to evolution as the fact and law of Nature, and guide their researches by its light, do not choose to have it publicly known that they are adherents of the doctrine. We are behind England in fair and tolerant treatment of the Darwinian question, but may expect the same improvement in this respect that Huxley tells us has taken place with the English. In a recent article he remarks : “ The gradual lapse of time has now separated us by more than a decade from the date of the publication of the ‘ Origin of Species ; ’ and whatever may be thought or said about Hr. Darwin’s doctrines, .or the manner in which he has propounded them, this much is certain, that, in a dozen years, the ‘ Origin of Species ’ has worked as complete a revolution in biological science as the ‘ Principia ’ did in astronomy—and it has done so, because, in the words of Helmholtz, it contains ‘ an essentially new creative thought.’ And, as time has slipped by, a happy change has come over Hr. Darwin’s critics. The mixture of ignorance and insolence which, at first, characterized a large proportion of the attacks with which he was assailed, is no longer the sad distinction of anti-Darwinian criticism. Instead of abusive nonsense, which merely discredited its writers, we read essays, which are, at worst, more or less intelligent and appreciative ; while, sometimes, like that which appeared in the North British Review for 1867, they have a real and permanent value.”


THE national educational association recently held at Elmira, N. Y., was of unusual interest, and evinced a marked progress in the public method of dealing with educational subjects. We have for some years refrained from attendance upon teachers’ conventions, having been wearied with the narrow technical range and pedantic pettiness of the discussions. But the recent meeting showed that educators are beginning to outgrow their old professional limitations, and to consider the various questions that come before them in the light of broad principles, and in the spirit of radical and rational improvement. Many men of ability, presidents of leading colleges, eminent professors, principals of high-schools, and State and city superintendents, were present, contributing valuable papers, and giving strength and character to the debates which followed them.

President HcCosh delivered an able address on the higher education, and maintained that the national Government should not give the balance of its lands to the agricultural colleges, nor yet to other collegiate institutions, but should appropriate them for the benefit of high-schools and academies throughout the country. Dr. McCosh thus stated his main position :

“ I don’t propose that any portion of this $90,000,000 should be given to colleges. We cannot aid all, and to select a few would be injurious. In regard to elementary education, the Northern, the Middle, and the W estern States, are able and willing to do their duty. I venture to propose that in these the unappropriated lands be devoted to the encouragement of secondary schools. Let each State obtain its share, and the money handed over to it under certain rigid rules and restrictions to prevent the abuse of the public money. In particular, to secure that upper schools be endowed only where needed, I suggest that money be allocated only when a district, or, it may be, a combination of two or more districts, has raised a certain portion, say one-half, of the necessary funds. By this means the money may be made to stimulate the erection of high-schools all over America. These schools would aid colleges far more powerfully than a direct grant to them, as, in fact, the grand difficulty which colleges have to contend against arises from there being so few schools fitted to prepare young men for them with their rising standard of excellence. But I plead for these schools, not merely as a means of feeding colleges, but as competent to give a high education in varied branches, literary and scientific, to a far greater number who do not go on to any thing higher. These schools, like the elementary schools, should be open to all children, of the poor as well as the rich. They should be set up, like the German gymnasium, in convenient localities, so that all the population may have access to them. They should embrace every useful branch suited to young men and women under sixteen and eighteen years of age—English composition, English language, history, classics, modern language, and elementary science. The best scholars in our primary schools would be drafted up to these higher schools, and thus the young talent of the country would be turned to good account, while the teachers in the common schools would be encouraged by seeing their best pupils advance.”

The discussion that followed this speech brought out difficulties which the doctor had not considered, and, in fact, opened the way to the most vital problem of American education. The colleges of the country represent the old scholastic culture which took its shape at a period when popular education was not thought of, and culture was confined to the professional classes. These institutions are not holding their own at the present time. Their students are falling off, for the reason that there is a decline in the academies by which the colleges are fed ; that is, as Dr. McCosh says, “ the grand difficulty which colleges have to contend against arises from there being so few schools fitted to prepare young men for them.”

But the cause of the decline of the academies is the rivalry of the newlyinstituted high-schools, and these are the outgrowth and now an essential part of the common - school system. The modern idea of universal education has become organized in such a way as to antagonize the old college system. The common schools are net constructed upon the scholastic pattern ; they aim to give to all a useful practical education, that shall be available in the common work of life. It was found that they did not go far enough in this direction for the wants of many, and so high-schools were organized in which the pupils of the common schools might graduate into the working world with a better preparation than the lower schools can furnish. It was stated in the discussion that but one in fifteen hundred of the population passes through college, while it is left for the common and high schools to educate the rest of the people. As the old academies disappear, therefore, the colleges seek to get control of the high-schools, to be used as feeders for themselves ; and this, of course, necessitates a high-school curriculum fitted to prepare young men for college. This is the point at which the two systems are unconform able, and is to be the point of conflict in the future. What shall be the course of study in the high-schools? Shall it be a sequel to the common schools, or a prelude to the colleges, for these are different things? Already in some of them we have two distinct systems of education. A principal of one of these institutions in the West said to the writer: “We are working under the disadvantages of a double curriculum. Wo have a scheme of studies, scientific and practical, drawn with reference to the larger number of our pupils who come from the common schools, and who close their studies with us. We take them through an English course, with mathematics, book-keeping, political economy, physics, chemistry, botany, and physiology. And we have also a classical course for a small number of students who are preparing for college. But the exactions of Latin and Greek are so great upon these that they get hardly a smattering of the subjects pursued by the other students.” The tactics of Dr. McCosh were admirable. To keep the proceeds of the public lands from going to the agricultural colleges and scientific institutions, he is willing to resign all claim upon them for the benefit of the classical colleges ; at the same time, if the money is expended for the extension of high-schools, as the doctor says, “these schools would aid colleges far more powerfully than a direct grant to them.” Yet, as long as the two systems of education remain so diverse that the regular high-school graduation is not accepted as preparation for college, there will be conflict for the control of these establishments. Only as the college curriculum becomes more broad, modern, and scientific, and the classical studies are restricted to the special classes who have need of them, can American education become harmonized in its elements and unified in its system.

TIIE report of President Eliot, of Harvard, on a national university, was a strong document. We publish the last portion of it, which deals with the main question, and ask attention to the

high grounds on which he bases his demand for the non-interference of government with the system of higher education. His paper started a warm debate on the broad and important question of the proper relations of government to the work of instruction, and, of course, his views met with vigorous opposition. It was maintained that there is no break in the logic by which government action is prescribed ; and that, admitting the propriety of state action in primary education, there is no halting-place until the government takes charge of the entire school machinery of the country. And such is the overshadowing influence of politics, and so profound the superstition regarding government omnipotence, that this view found its urgent advocates, who seem blind to the consequences that are certain to follow when the people shirk the responsibilities of attending directly to the education of the young, and shoulder it off upon a mass of politicians holding the offices of government. The friends of stato education certainly pressed their case to its extreme conclusions. Government contributes money to support common schools, and appoints officers to regulate them ; therefore let it appropriate $20,000,000 to establish a national university at Washington, with $1,000,000 a year to be divided among the congressional appointees, who will hold the professorships. Dr. McCosh suggested that recent congressional experiences were hardly calculated to inspire confidence in the action of that body, and asked what guarantee we should have against a university ring and systematic educational jobbing ; and it was objected by others that the class of men who congregate in the capital, and the whole spirit of the place, would make it more unfit than any other in the country for such an institution. Prof. Bichards, of Washington, came to the rescue of the reputation of his town, and asked, emphatically, “Where do its knaves and rascals come from? We do not make them ; you send them to us from all parts of the nation.” But the argument was not helped by the retort, for it is quite immaterial whether Washington breeds its scoundrels or imports them. If our republican system is one that sifts out its most venal and unscrupulous intriguers and sharpers, and gathers them into one place, it is questionable whether that place had better not be avoided as the seat of a great model university—especially if said intriguers and sharpers are to have the management of it.


IN an instructive article upon this subject, the Nation says : “ There was a vague but very general impression, a few years ago, that, if the elective system were introduced into the older American colleges, the practical sciences, as they are called, especially physics, chemistry, and natural history, would crowd out the study of the ancient languages. There was also a feeling that the obvious utility of the modern languages, and particularly of French and of German, would help to throw the “ dead languages ” into the background. A great many enthusiasts fancied that the good time a-coming was at hand, when books would be thrown aside, and all intellectual activity would be narrowed down to the study of physical Nature ; and so much noise has been made about the natural sciences that a great many people undoubtedly think this is the principal if not the only subject taught where an elective system prevails.”

To submit this matter to a test, and “ ascertain what it is that the mass of students feel the need of most and flock to most when the choice is left entirely to themselves,” the Nation overhauls the university catalogue of Harvard for 1872-73, and presents the statistics which bear upon the subject. The “ elections ” of subjects of study or choices of the students are shown in a succession of tables, the last of which divides the college studies into “disciplinary ” and “ practical,” and exhibits the results as follows :


“By this arrangement the disciplinary studies preponderate over the practical in the ratio of 185:145 or 100: 78.”

Upon this the Nation proceeds to remark: “ The figures show conclusively that, in spite of the crusade which has been carried on against the ancient languages, they are still full of vitality, still a power, still a popular study, and, in fact, the greatest interest in the little college world. As our inquiry is purely numerical and statistical, we do not ask why the students make the selections they do. Doubtless, the reasons are not very obvious ; still, one fact is plain, that they are not guided wholly by utilitarian views.”

Now, if the Nation had looked a little into the “why” of this matter, we are sure it would have found the reasons for this state of things obvious enough, and, although it might have somewhat qualified its conclusion, it would have made the statement more valuable. The number of votes cast at an election is usually an expression of public opinion, but, if in any case there happen to have been military interference and dictation, the numerical report of ballots cast, if taken alone, would be misleading. We are told that the working of the option system at Harvard affords an indication of the preferences and tendencies of the students in regard to the studies they incline to pursue ; but is not entrance to Harvard a part of its policy, and what about the option there ? Is there not at the door of the university a big winnowingmachine which delivers the “disciplinary ” studies as acceptable wheat, and blows the “ utilitarian ” studies to the winds as the veriest chaff ? All the preparation exacted of students for entrance to college is in the “ disciplinary ” studies, and mainly in the Latin and Greek languages. Besides being incessantly told in the preparatory schools that the very poles of the intellectual world are two dead languages, and that a classical education is the only real broad liberal education, they are kept for years drilling at Latin and Greek as the only condition upon which they can get to college at all. The standard is here kept as high as it was twenty years ago, and President Eliot stated at the late Elmira convention that, in the estimation of the preparatory teachers in New England, Harvard requires a year more study of Latin and Greek than the other colleges. The student thus enters college warped and biassed by his preparation for it. Of the sciences he knows nothing, and he is prejudiced against them as mere utilitarian studies to be contrasted on all occasions with liberal mental pursuits. When these facts are remembered, it is certainly no matter of surprise that Latin and Greek lead in the collegiate elections of study ; it is rather surprising that they lead by so small a number. It is very far from being a fair or open choice when a pupil has to repudiate his past acquisitions, and stein the tide of opinion which has forced them upon him, to take up studies under the grave disadvantage of no early preparation. We think the lesson of the Harvard statistics is not altogether exhilarating to the partisans of the classics. When Harvard will accept a scientific preparation for college as of equal value with the classical, we shall be better prepared to estimate the strength of the tendencies in the two directions.


THE biographer of Sir Walter Scott alludes to a “ first love ” which ended unfortunately for the great romancer. It is related that, rain happening to fall one Sunday after church-time, Scott offered his umbrella to a young lady, and, the tender having been accepted, he escorted her to her home. The acquaintance was continued, and ripened iuto a strong attachment on the part of Scott ; hut he was doomed to disappointment, and Lockhart states that it produced a profound effect upon his character. “Keble, in a beautiful essay on Scott, more than hints a belief that it was this imaginary regret haunting Scott all his life long which became the true well-spring of his inspiration in all his minstrelsy and romance.” Be that as it may, the lady, whose name was Williamina Belches, instead of marrying Scott, chose his friend, Sir William Forbes. They had a family, of which the youngest, James David, was born in 1809. When the son was nineteen years old his father died, and, under the immediate influence of the bereavement, he drew up a set of brief resolutions for the regulation of his life, one of which was “ to curb pride and over-anxiety in the pursuit of worldly objects, especially fame.” Young Forbes became a famous man. He took to science, and mastered it rapidly under the guidance of his intimate friend Sir David Brewster, choosing physics as his department. At the death of Sir John Leslie, Professor of Natural Philosophy in the University of Edinburgh, he offered himself as a candidate for the chair, in opposition to his old friend Brewster and others, and was elected to the position at the age of twenty-four. He was an original investigator in a wide field of physics, contributed to the extension of knowledge in many directions, and was an able writer. His health failing, he resigned his chair in the Edinburgh University, and accepted the principalship of St. Andrew’s, and is therefore known as Principal Forbes. He died the last day of 1868, and an elaborate biography, by three of his Scotch friends, has just been published by Macmillan, which is an extremely interesting book.

Among other subjects of his investigation were the glaciers, upon which he published an important volume. He met Agassiz in the Alps, while that gentleman was experimenting upon glacial motions, and they made observations together, but subsequently fell out with each other about the division of the honors of discovery. The complication extended, involving the claims of Bishop Rendu, Prof. Guyot, and others. In his “ Glaciers of the Alps,” published in 1860, Prof. Tyndall undertook to do justice to the claims of all parties. Prof. Forbes was not satisfied with the awards, and replied to Prof. Tyndall’s work, vindicating his own claims to a larger share of the investigation than had been accorded him. To this Prof. Tyndall at the time made no rejoinder ; but in his recently-published “Forms of Water” he restated the case in a way that was not satisfactory to Forbes’s biographers, who have met it by an appendix to the volume. In the Contemporary Review for August, Prof. Tyndall returns to the question in an elaborate paper, entitled “ Principal Forbes and his Biographers,” of which we publish the first and last portions, that are of most general interest. We have not space for the whole article, which is long, and omitted the extended extracts from Rendu’s work in French, and that portion of the argument which will mainly concern the special students of glacial literature. In an introductory note to the article, Prof. Tyndall briefly states the origin and cause of the controversy, and earnestly deprecates its present revival. He says, speaking of the biographers : “I am challenged to meet their criticisms, which, I find, are considered to be conclusive by some able public journals and magazines. Thus the attitude of a controversialist is once more forced upon me. Since the death of Principal Forbes no one has heard me utter a word inconsistent with tenderness for his memory ; and it is with an' unwillingness amounting to repugnance that I now defend myself across his grave. His biographers profess to know what he would have done were he alive, and hold themselves to be the simple executors of his will. I cannot act entirely upon this assumption, or deal with the dead as I should with the living. Hence, though these pages may appear to some to be sufficiently full, they lack the completeness, and still more the strength, which I should have sought to confer upon them had my present position been forced upon me by Principal Forbes himself instead of by his friends.”

It is to be feared that Prof. Forbes did not sufficiently abide by the rule of life which was formed under the solemn circumstances of his father’s death.

WE commend to the attention of our scientific readers, with philosophical inclinations, the series of articles on “ The Primary Concepts of Modern Physical Science,” the first of which appears this month, on “The Theory of the Atomic Constitution of Matter.” The depth and force of the criticism are only equalled by the clearness of the conceptions, and the precision and felicity of the statement. The interest of the discussion will not be lessened when we say that H is by an Ohio lawyer—formerly a judge of Cincinnati. It has been held as one of the redeeming features of the English bar, that the author of the able and admirable essay on “The Correlation of Forces ” belongs to it ; and it is certainly to the credit of the legal profession in this country that a member of it has cultivated physical philosophy to such excellent purpose as is evinced by the article we now publish.
