"It is pleasant to find an American book which can rank with the very best of foreign works on this subject. Professor Le Conte has long been known as an original investigator in this department; all that he gives us is treated with a master-hand."—The Nation.
Animal Life,
As affected by the Natural Conditions of Existence. By Karl Semper, Professor of the University of Würzburg. With Two Maps and One Hundred and Six Woodcuts, and Index. 12mo. Cloth, $2.00.
"It appears to me that, of all the properties of the animal organism, Variability is that which may first and most easily be traced by exact investigation to its efficient causes; and as it is beyond a doubt the subject around which, at the present moment, the strife of opinions is most violent, it is that which will be most likely to repay the trouble of closer research. I have endeavored to facilitate this task so far as in me lies."—From the Preface.
The Atomic Theory.
By Ad. Wurtz, Membre de l'Institut; Doyen Honoraire de la Faculté de Médecine; Professeur à la Faculté des Sciences de Paris. Translated by E. Cleminshaw, M. A., F. C. S., F. I. C., Assistant Master at Sherborne School. 12mo. Cloth, $1.50.
"There was need for a book like this, which discusses the atomic theory both in its historic evolution and in its present form. And perhaps no man of this age could have been selected so able to perform the task in a masterly way as the illustrious French chemist, Adolph Wurtz. It is impossible to convey to the reader, in a notice like this, any adequate idea of the scope, lucid instructiveness, and scientific interest of Professor Wurtz's book. The modern problems of chemistry, which are commonly so obscure from imperfect exposition, are here made wonderfully clear and attractive."—The Popular Science Monthly.
