_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 analogous, 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._
