" In the volume now published, Professor Tyndall has presented a noble illustratioa 

 oftheacuteness 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 intncate scientific

"The 'Forms of Water,' by Professor Tyndall, is an mteresting 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 m- 

 vestigationsofthe best scientific minds, "-^^^^^^^^^w^w^-^- 



" This series is admirably commenced by this little volume from the pen of Prof. 

 Tvndall. A perfect master of his subject, he presents in a style easy and attractive his 

 methods of investigarion, 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 channmg. 

 but also original and suggestive in the highest degree. -Nowhere since the publicatioii 

 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 mtentions, we are 

 conscious of having given but a sorry account of it in '^-^^^^ P^^^^^P'j" J";,"'' 

 hope we have said enough to commend it to the attention of the thoughtful leader. - 

 Prof. John Fiske, in the Atlantic Moitthly. . . 



''Mr. Bagehot's style is clear and vigorous. We refram from giving a fuler ac 

 count of these suggestive essays, only because we are sure that --J-^-; 7^;^^;"^'
