Opinions of the Press on the "International Scientific Series." 



Tyndall's Forms of Water. 



I vol., I2mo. 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 in- 

 vestigations 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 con- 

 ception of all the wondrous transformations to which water is subjected." Churchman.

Bagehot's Physics and Politics. 



I vol., I2mo. 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 sug- 

 gested in the course of a couple of hundred pages. . . . To do 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 FISKE, in the Atlantic 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."-- 

 A thenteum. 



" Mr. Bagehot discusses an immense variety of topics connected with the progress 

 of societies and nations, and the development of their distinctive peculiarities; and hu 

 book shows an abundance of ingenious and original thought "ALFRED RUSSELI 

 WALLACK, in Nature.
