INDEX.

Opinions of the Press on the “International Scientific Series.”

I.

Tyndall’s Forms of Water.

1 vol., 12mo. Cloth. Illustrated.Price, $1.50.

“In the volume now published, Professor Tyndall has presented a noble illustration of the acuteness and subtlety of his intellectual powers, the scope and insight of his scientific vision, his singular command of the appropriate language of exposition, and the peculiar vivacity and grace with which he unfolds the results of intricate scientific research.”—N. Y. Tribune.

“The ‘Forms of Water,’ by Professor Tyndall, is an interesting and instructive little volume, admirably printed and illustrated. Prepared expressly for this series, it is in some measure a guarantee of the excellence of the volumes that will follow, and an indication that the publishers will spare no pains to include in the series the freshest investigations of the best scientific minds.”—Boston Journal.

“This series is admirably commenced by this little volume from the pen of Prof. Tyndall. A perfect master of his subject, he presents in a style easy and attractive his methods of investigation, and the results obtained, and gives to the reader a clear conception of all the wondrous transformations to which water is subjected.”—Churchman.

II.

Bagehot’s Physics and Politics.

1 vol., 12mo. Price, $1.50.

“If the ‘International Scientific Series’ proceeds as it has begun, it will more than fulfil the promise given to the reading public in its prospectus. The first volume, by Professor Tyndall, was a model of lucid and attractive scientific exposition; and now we have a second, by Mr. Walter Bagehot, which is not only very lucid and charming, but also original and suggestive in the highest degree. Nowhere since the publication of Sir Henry Maine’s ‘Ancient Law,’ have we seen so many fruitful thoughts suggested in the course of a couple of hundred pages.... To do justice to Mr. Bagehot’s fertile book, would require a long article. With the best of intentions, we are conscious of having given but a sorry account of it in these brief paragraphs. But we hope we have said enough to commend it to the attention of the thoughtful reader.”—Prof. John Fiske, in the Atlantic Monthly.

“Mr. Bagehot’s style is clear and vigorous. We refrain from giving a fuller account of these suggestive essays, only because we are sure that our readers will find it worth their while to peruse the book for themselves; and we sincerely hope that the forthcoming parts of the ‘International Scientific Series’ will be as interesting.”—Athenæum.

“Mr. Bagehot discusses an immense variety of topics connected with the progress of societies and nations, and the development of their distinctive peculiarities; and his book shows an abundance of ingenious and original thought.”—Alfred Russell Wallace, in Nature.

III.

Foods.

By Dr. EDWARD SMITH.

1 vol., 12mo. Cloth. Illustrated.Price, $1.75.

In making up The International Scientific Series, Dr. Edward Smith was selected as the ablest man in England to treat the important subject of Foods. His services were secured for the undertaking, and the little treatise he has produced shows that the choice of a writer on this subject was most fortunate, as the book is unquestionably the clearest and best-digested compend of the Science of Foods that has appeared in our language.

“The book contains a series of diagrams, displaying the effects of sleep and meals on pulsation and respiration, and of various kinds of food on respiration, which, as the results of Dr. Smith’s own experiments, possess a very high value. We have not far to go in this work for occasions of favorable criticism; they occur throughout, but are perhaps most apparent in those parts of the subject with which Dr. Smith’s name is especially linked.”—London Examiner.

“The union of scientific and popular treatment in the composition of this work will afford an attraction to many readers who would have been indifferent to purely theoretical details.... Still his work abounds in information, much of which is of great value, and a part of which could not easily be obtained from other sources. Its interest is decidedly enhanced for students who demand both clearness and exactness of statement, by the profusion of well-executed woodcuts, diagrams, and tables, which accompany the volume.... The suggestions of the author on the use of tea and coffee, and of the various forms of alcohol, although perhaps not strictly of a novel character, are highly instructive, and form an interesting portion of the volume.”—N. Y. Tribune.

IV.

Body and Mind.

THE THEORIES OF THEIR RELATION.

By ALEXANDER BAIN, LL. D.

1 vol., 12mo. Cloth.Price, $1.50.

Professor Bain is the author of two well-known standard works upon the Science of Mind—“The Senses and the Intellect,” and “The Emotions and the Will.” He is one of the highest living authorities in the school which holds that there can be no sound or valid psychology unless the mind and the body are studied, as they exist, together.

“It contains a forcible statement of the connection between mind and body, studying their subtile interworkings by the light of the most recent physiological investigations. The summary in Chapter V., of the investigations of Dr. Lionel Beale of the embodiment of the intellectual functions in the cerebral system, will be found the freshest and most interesting part of his book. Prof. Bain’s own theory of the connection between the mental and the bodily part in man is stated by himself to be as follows: There is ‘one substance, with two sets of properties, two sides, the physical and the mental—a double-faced unity.’ While, in the strongest manner, asserting the union of mind with brain, he yet denies ‘the association of union in place, but asserts the union of close succession in time,’ holding that ‘the same being is, by alternate fits, under extended and under unextended consciousness.’”—Christian Register.

V.

The Study of Sociology.

By HERBERT SPENCER.

1 vol., 12mo. Cloth.Price, $1.50.

“The philosopher whose distinguished name gives weight and influence to this volume, has given in its pages some of the finest specimens of reasoning in all its forms and departments. There is a fascination in his array of facts, incidents, and opinions, which draws on the reader to ascertain his conclusions. The coolness and calmness of his treatment of acknowledged difficulties and grave objections to his theories win for him a close attention and sustained effort, on the part of the reader, to comprehend, follow, grasp, and appropriate his principles. This book, independently of its bearing upon sociology, is valuable as lucidly showing what those essential characteristics are which entitle any arrangement and connection of facts and deductions to be called a science.”—Episcopalian.

“This work compels admiration by the evidence which it gives of immense research, study, and observation, and is, withal, written in a popular and very pleasing style. It is a fascinating work, as well as one of deep practical thought.”—Bost. Post.

“Herbert Spencer is unquestionably the foremost living thinker in the psychological and sociological fields, and this volume is an important contribution to the science of which it treats.... It will prove more popular than any of its author’s other creations, for it is more plainly addressed to the people and has a more practical and less speculative cast. It will require thought, but it is well worth thinking about.”—Albany Evening Journal.

VI.

The New Chemistry.

By JOSIAH P. COOKE, Jr.,

Erving Professor of Chemistry and Mineralogy in Harvard University.

1 vol., 12mo. Cloth.Price, $2.00.

“The book of Prof. Cooke is a model of the modern popular science work. It has just the due proportion of fact, philosophy, and true romance, to make it a fascinating companion, either for the voyage or the study.”—Daily Graphic.

“This admirable monograph, by the distinguished Erving Professor of Chemistry in Harvard University, is the first American contribution to ‘The International Scientific Series,’ and a more attractive piece of work in the way of popular exposition upon a difficult subject has not appeared in a long time. It not only well sustains the character of the volumes with which it is associated, but its reproduction in European countries will be an honor to American science.”—New York Tribune.

“All the chemists in the country will enjoy its perusal, and many will seize upon it as a thing longed for. For, to those advanced students who have kept well abreast of the chemical tide, it offers a calm philosophy. To those others, youngest of the class, who have emerged from the schools since new methods have prevailed, it presents a generalization, drawing to its use all the data, the relations of which the newly-fledged fact-seeker may but dimly perceive without its aid.... To the old chemists, Prof. Cooke’s treatise is like a message from beyond the mountain. They have heard of changes in the science; the clash of the battle of old and new theories has stirred them from afar. The tidings, too, had come that the old had given way; and little more than this they knew.... Prof. Cooke’s ‘New Chemistry’ must do wide service in bringing to close sight the little known and the longed for.... As a philosophy it is elementary, but, as a book of science, ordinary readers will find it sufficiently advanced.”—Utica Morning Herald.

VII.

The Conservation of Energy.

By BALFOUR STEWART, LL. D., F. R. S.

With an Appendix treating of the Vital and Mental Applications of the Doctrine.

1 vol., 12mo. Cloth. Price, $1.50.

“The author has succeeded in presenting the facts in a clear and satisfactory manner, using simple language and copious illustration in the presentation of facts and principles, confining himself, however, to the physical aspect of the subject. In the Appendix the operation of the principles in the spheres of life and mind is supplied by the essays of Professors Le Conte and Bain.”—Ohio Farmer.

“Prof. Stewart is one of the best known teachers in Owens College in Manchester.

“The volume of The International Scientific Series now before us is an excellent illustration of the true method of teaching, and will well compare with Prof. Tyndall’s charming little book in the same series on ‘Forms of Water,’ with illustrations enough to make clear, but not to conceal his thoughts, in a style simple and brief.”—Christian Register, Boston.

“The writer has wonderful ability to compress much information into a few words. It is a rich treat to read such a book as this, when there is so much beauty and force combined with such simplicity.”—Eastern Press.

VIII.

Animal Locomotion;

Or, WALKING, SWIMMING, AND FLYING.

With a Dissertation on Aëronautics.

By J. BELL PETTIGREW, M. D., F. R. S., F. R. S. E.,
F. R. C. P. E.

1 vol., 12mo.Price, $1.75.

“This work is more than a contribution to the stock of entertaining knowledge, though, if it only pleased, that would be sufficient excuse for its publication. But Dr. Pettigrew has given his time to these investigations with the ultimate purpose of solving the difficult problem of Aëronautics. To this he devotes the last fifty pages of his book. Dr. Pettigrew is confident that man will yet conquer the domain of the air.”—N. Y. Journal of Commerce.

“Most persons claim to know how to walk, but few could explain the mechanical principles involved in this most ordinary transaction, and will be surprised that the movements of bipeds and quadrupeds, the darting and rushing motion of fish, and the erratic flight of the denizens of the air, are not only anologous, but can be reduced to similar formula. The work is profusely illustrated, and, without reference to the theory it is designed to expound, will be regarded as a valuable addition to natural history.”—Omaha Republic.

IX.

Responsibility in Mental Disease.

By HENRY MAUDSLEY, M. D.,

Fellow of the Royal College of Physicians; Professor of Medical Jurisprudence in University College, London.

1 vol., 12mo. Cloth.Price, $1.50.

“Having lectured in a medical college on Mental Disease, this book has been a feast to us. It handles a great subject in a masterly manner, and, in our judgment, the positions taken by the author are correct and well sustained.”—Pastor and People.

“The author is at home in his subject, and presents his views in an almost singularly clear and satisfactory manner.... The volume is a valuable contribution to one of the most difficult, and at the same time one of the most important subjects of investigation at the present day.”—N. Y. Observer.

“It is a work profound and searching, and abounds in wisdom.”—Pittsburg Commercial.

“Handles the important topic with masterly power, and its suggestions are practical and of great value.”—Providence Press.

X.

The Science of Law.

By SHELDON AMOS, M. A.,

Professor of Jurisprudence in University College, London; author of “A Systematic
View of the Science of Jurisprudence,” “An English Code, its Difficulties
and the Modes of overcoming them,” etc., etc.

1 vol., 12mo. Cloth.Price, $1.75.

“The valuable series of ‘International Scientific’ works, prepared by eminent specialists, with the intention of popularizing information in their several branches of knowledge, has received a good accession in this compact and thoughtful volume. It is a difficult task to give the outlines of a complete theory of law in a portable volume, which he who runs may read, and probably Professor Amos himself would be the last to claim that he has perfectly succeeded in doing this. But he has certainly done much to clear the science of law from the technical obscurities which darken it to minds which have had no legal training, and to make clear to his ‘lay’ readers in how true and high a sense it can assert its right to be considered a science, and not a mere practice.”—The Christian Register.

“The works of Bentham and Austin are abstruse and philosophical, and Maine’s require hard study and a certain amount of special training. The writers also pursue different lines of investigation, and can only be regarded as comprehensive in the departments they confined themselves to. It was left to Amos to gather up the result and present the science in its fullness. The unquestionable merits of this, his last book, are, that it contains a complete treatment of a subject which has hitherto been handled by specialists, and it opens up that subject to every inquiring mind.... To do justice to ‘The Science of Law’ would require a longer review than we have space for. We have read no more interesting and instructive book for some time. Its themes concern every one who renders obedience to laws, and who would have those laws the best possible. The tide of legal reform which set in fifty years ago has to sweep yet higher if the flaws in our jurisprudence are to be removed. The process of change cannot be better guided than by a well-informed public mind, and Prof. Amos has done great service in materially helping to promote this end.”—Buffalo Courier.

XI.

Animal Mechanism,

A Treatise on Terrestrial and Aërial Locomotion.

By E. J. MAREY,

Professor at the College of France, and Member of the Academy of Medicine.

With 117 Illustrations, drawn and engraved under the direction of the author.

1 vol., 12mo. Cloth.Price, $1.75

“We hope that, in the short glance which we have taken of some of the most important points discussed in the work before us, we have succeeded in interesting our readers sufficiently in its contents to make them curious to learn more of its subject-matter. We cordially recommend it to their attention.

“The author of the present work, it is well known, stands at the head of those physiologists who have investigated the mechanism of animal dynamics—indeed, we may almost say that he has made the subject his own. By the originality of his conceptions, the ingenuity of his constructions, the skill of his analysis, and the perseverance of his investigations, he has surpassed all others in the power of unveiling the complex and intricate movements of animated beings.”—Popular Science Monthly.

XII.

History of the Conflict between
Religion and Science.

By JOHN WILLIAM DRAPER, M. D., LL. D.,

Author of “The Intellectual Development of Europe.”

1 vol., 12mo.Price, $1.75.

“This little ‘History’ would have been a valuable contribution to literature at any time, and is, in fact, an admirable text-book upon a subject that is at present engrossing the attention of a large number of the most serious-minded people, and it is no small compliment to the sagacity of its distinguished author that he has so well gauged the requirements of the times, and so adequately met them by the preparation of this volume. It remains to be added that, while the writer has flinched from no responsibility in his statements, and has written with entire fidelity to the demands of truth and justice, there is not a word in his book that can give offense to candid and fair-minded readers.”—N. Y. Evening Post.

“The key-note to this volume is found in the antagonism between the progressive tendencies of the human mind and the pretensions of ecclesiastical authority, as developed in the history of modern science. No previous writer has treated the subject from this point of view, and the present monograph will be found to possess no less originality of conception than vigor of reasoning and wealth of erudition.... The method of Dr. Draper, in his treatment of the various questions that come up for discussion, is marked by singular impartiality as well as consummate ability. Throughout his work he maintains the position of an historian, not of an advocate. His tone is tranquil and serene, as becomes the search after truth, with no trace of the impassioned ardor of controversy. He endeavors so far to identify himself with the contending parties as to gain a clear comprehension of their motives, but, at the same time, he submits their actions to the tests of a cool and impartial examination.”—N. Y. Tribune.

XIII.

THE DOCTRINE OF

Descent, and Darwinism.

By OSCAR SCHMIDT,

Professor in the University of Strasburg.

With 26 Woodcuts.

1 vol., 12mo. Cloth.Price, $1.50.

“The entire subject is discussed with a freshness, as well as an elaboration of detail, that renders his work interesting in a more than usual degree. The facts upon which the Darwinian theory is based are presented in an effective manner, conclusions are ably defended, and the question is treated in more compact and available style than in any other work on the same topic that has yet appeared. It is a valuable addition to the ‘International Scientific Series.’”—Boston Post.

“The present volume is the thirteenth of the ‘International Scientific Series,’ and is one of the most interesting of all of them. The subject-matter is handled with a great deal of skill and earnestness, and the courage of the author in avowing his opinions is much to his credit.... This volume certainly merits a careful perusal.”—Hartford Evening Post.

“The volume which Prof. Schmidt has devoted to this theme is a valuable contribution to the Darwinian literature. Philosophical in method, and eminently candid, it shows not only the ground which Darwin had in his researches made, and conclusions reached before him to plant his theory upon, but shows, also, what that theory really is, a point upon which many good people who talk very earnestly about the matter are very imperfectly informed.”—Detroit Free Press.

XIV.

The Chemistry of Light and Photography;

In its Application to Art, Science, and Industry.

By Dr. HERMANN VOGEL,

Professor in the Royal Industrial Academy of Berlin.

With 100 Illustrations.

12mo.Price, $2.00.

“Out of Photography has sprung a new science—the Chemistry of Light—and, in giving a popular view to the one, Dr. Vogel has presented an analysis of the principles and processes of the other. His treatise is as entertaining as it is instructive, pleasantly combining a history of the progress and practice of photography—from the first rough experiments of Wedgwood and Davy with sensitized paper, in 1802, down to the latest improvements of the art—with technical illustrations of the scientific theories on which the art is based. It is the first attempt in any manual of photography to set forth adequately the just claims of the invention, both from an artistic and a scientific point of view, and it must be conceded that the effort has been ably conducted.”—Chicago Tribune.

XV.

Fungi;

THEIR NATURE, INFLUENCE, AND USES.

By M. C. COOKE, M. A., LL. D.

Edited by Rev. M. J. BERKELEY, M. A., F. L. S.

With 109 Illustrations. Price, $1.50.

“Even if the name of the author of this work were not deservedly eminent, that of the editor, who has long stood at the head of the British fungologists, would be a sufficient voucher for the accuracy of one of the best botanical monographs ever issued from the press.... The structure, germination, and growth of all these widely-diffused organisms, their habitats and influences for good and evil, are systematically described.”—New York World.

“Dr. Cooke’s book contains an admirable résumé of what is known on the structure, growth, and reproduction of fungi, together with ample bibliographical references to original sources of information.”—London Athenæum.

“The production of a work like the one now under review represents a large amount of laborious, difficult, and critical work, and one in which a serious slip or fatal error would be one of the easiest matters possible, but, as far as we are able to judge, the new hand-book seems in every way well suited to the requirements of all beginners in the difficult and involved study of fungology.”—The Gardener’s Chronicle (London).

XVI.

The Life and Growth of Language:

AN OUTLINE OF LINGUISTIC SCIENCE.

By WILLIAM DWIGHT WHITNEY,

Professor of Sanskrit and Comparative Philology in Yale College.

1 vol., 12mo. Cloth. Price, $1.50.

“Prof. Whitney is to be commended for giving to the public the results of his ripe scholarship and unusually profound researches in simple language. He draws illustrations and examples of the principles which he wishes to impact, from common life and the words in frequent use.

“The topics discussed in this volume are, for the most part, those which have been already treated by other writers on philology, and even by the author himself, in his volume on ‘Language, and the Study of Language,’ published a few years ago, and, though many of the truths here set forth are those with which students in the same line of investigation are generally familiar, all will rejoice to see them restated in such a fresh and simple way.

“This work, while valuable to scholars, will be interesting to every one.”—The Churchman.

“This work is an important contribution to a science which has advanced steadily under conditions that appear constantly to throw an increasing light on difficult questions, and at each step clear the way for further discoveries.”—Chicago Inter-Ocean.

“Prof. Whitney is undoubtedly one of the foremost of English-speaking philologists, and occupies an enviable position in the wider circle of European students of language.

“His style, clear, simple, picturesque, abounding in striking illustrations, and apt in comparisons, is admirably fitted to be the vehicle of a popular treatise like the work under consideration.”—Portland Daily Press.

XVII.

Money and the Mechanism of Exchange.

By W. STANLEY JEVONS, M. A., F. R. S.,

Professor of Logic and Political Economy in the Owens College, Manchester.

1 vol., 12mo. Cloth. Price, $1.75.

“He offers us what a clear-sighted, cool-headed, scientific student has to say on the nature, properties, and natural laws of money, without regard to local interests or national bias. His work is popularly written, and every page is replete with solid instruction of a kind that is just now lamentably needed by multitudes of our people who are victimized by the grossest fallacies.”—Popular Science Monthly.

“If Professor Jevons’s book is read as extensively as it deserves to be, we shall have sounder views on the use and abuse of money, and more correct ideas on what a circulating medium really means.”—Boston Saturday Evening Gazette.

“Professor Jevons writes in a sprightly but colorless style, without trace of either prejudice or mannerism, and shows no commitment to any theory. The time is not very far distant, we hope, when legislators will cease attempting to legislate upon money before they know what money is, and, as a possible help toward such a change, Professor Jevons deserves the credit of having made a useful contribution to a department of study long too much neglected, but of late years, we are gratified to say, becoming less so.”—The Financier, New York.

XVIII.

The Nature of Light,

WITH A GENERAL ACCOUNT OF PHYSICAL OPTICS.

By Dr. EUGENE LOMMEL

(University of Erlangen).

1 vol., 12mo. Cloth.Price, $2.00.

“In the present treatise, Professor Lommel has given an admirable outline of the nature of light and the laws of optics.

“Unlike most other writers on this subject, the author has, we think, wisely postponed all reference to theories of the nature of light, until the laws of reflection, refraction, and absorption, have been clearly set before the reader. Then, in the fifteenth chapter, Professor Lommel discusses Fresnel’s famous interference experiment, and leads the reader to see that the undulatory theory is the only conclusion that can be satisfactorily arrived at. A clear exposition is now given of Huyghen’s theory, after which follow several chapters on the diffraction and polarization of light-bearing waves.

“The reader is thus led onward much in the same way as the science itself has unfolded, and this, we think, is the surest and best way of teaching natural knowledge.

“We have said enough to show that Professor Lommel’s treatise is a useful contribution to the ‘International Series’—a book that can thoroughly be understood and enjoyed by any intelligent reader who may not have had any special scientific training.”—Nature.

“In a style singularly lucid, considering the abstruse nature of the subject treated, Dr. Lommel unfolds the learning of the scientists on the nature and phenomena of light.”—Philadelphia Inquirer.

“As a popular introduction to physical optics, it would be difficult to find a more satisfactory work than the one by Dr. Lommel, which has just appeared in the excellent ‘International Scientific Series.’”—The English Mechanic.

D. APPLETON & CO., Publishers, 549 & 551 Broadway, N. Y.

THE INTERNATIONAL SCIENTIFIC SERIES.

D. Appleton & Co. have the pleasure of announcing that they have made arrangements for publishing, and have recently commenced the issue of, a Series of Popular Monographs, or small works, under the above title, which will embody the results of recent inquiry in the most interesting departments of advancing science.

THE

POPULAR SCIENCE MONTHLY,

CONDUCTED BY
Professor E. L. YOUMANS.

The growing importance of scientific knowledge to all classes of the community calls for more efficient means of diffusing it. The Popular Science Monthly has been started to promote this object, and supplies a want met by no other periodical in the United States.

It contains instructive and attractive articles, and abstracts of articles, original, selected, and illustrated, from the leading scientific men of different countries, giving the latest interpretations of natural phenomena, explaining the applications of science to the practical arts, and to the operations of domestic life.

It is designed to give especial prominence to those branches of science which help to a better understanding of the nature of man; to present the claims of scientific education; and the bearings of science upon questions of society and government. How the various subjects of current opinion are affected by the advance of scientific inquiry will also be considered.

In its literary character, this periodical aims to be popular, without being superficial, and appeals to the intelligent reading-classes of the community. It seeks to procure authentic statements from men who know their subjects, and who will address the non-scientific public for purposes of exposition and explanation.

It will have contributions from Herbert Spencer, Professor Huxley, Professor Tyndall, Mr. Darwin, and other writers identified with speculative thought and scientific investigation.

THE POPULAR SCIENCE MONTHLY is published in a large octavo, handsomely printed on clear type. Terms, Five Dollars per annum, or Fifty Cents per copy.
