“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.

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.
