Opinions of the Press on the “International Scientific Series.” 
Tyndall's Forms of Water. 
1vol.,12mo. Cloth. Illustrated. . . . . . . .~ Price, $1.50. 
“<Tn 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.” —V. VY. Trzbuze. 
“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 in- 
vestigations of the best scientific minds.” —Boston Fournal. 
‘‘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 con- 
ception of all the wondrous transformations to which water is subjected.” —Churchman.

Bagehot's Physics and Politics. 
I vol., I2mo. Price, $1.50. 
“Tf 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 sug- 
gested in the course of a couple of hundred pages. . . . Todo justice to Mr. Bage- 
hot’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 Fiskk, in the 4 tlantic Monthly. 
““Mr. Bagehot’s style is clear and vigorous. We refrain from giving a fuller ac- 
count 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.” — 
Atheneum. 
“*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 RUSSELE
