University. 395 pp. 8vo. $2.00, net. Postage 15 cents. 
A simple and concise discussion for the educated layman 
of present-day scientific criticism of the Darwinian selection 
theories, together with concise accounts of the 6ther more im- 
portant proposed auxiliary and alternative theories of species- 
forming. 
President David Starr Jordan in The Dial:—lIts value can- 
not be over-estimated. A book the student must have at hand 
at all times, and it takes the place of a whole library. No 
other writer has attempted to gather together the scattered 
literature of this vast subject, and none has subjected this 
literature to such uniformly trenchant and uniformly kindly 
criticism. «An investigator of the first rank, and master of 
a clear and forceful literary style. 
New York Sun:—Can write in English as brightly and as 
clearly as the old-time Frenchmen. ... In his text he explains 
the controversy so that the plain man may understand it, while 
in the notes he adduces the evidence that the specialist re- 
quires. ... A brilliant book that deserves general attention.

By Witriam A. Locy, Professor in Northwestern University. 
460 pp. 8vo. $2.75, net. By mail, $2.88. 
An untechnical account of the rise and progress of biology; 
written around the lives of the great leaders, with bibliography

them rare, df nearly all the founders of biology. The book is 
divided into two parts: Part I dealing with the sources of 
biological ideas except those of Organic Evolution, and Part 
Il devoting itself wholly to Evolution. 
The Dial:—It is entertainingly written, and, better than any 
other existing single work in any language, gives the layman a 
clear idea of the scope and development of the broad science 
of biology. 
The Nation:—Whether the reader be layman, or a college 
student, or a biologist whose life work is nearing completion, 
this summary of achievements will be an inspiration. Intro- 
duces us in a charming way to the human side of the scientists. 
A well chosen reading list, an excellent index.
