Ke Hogg's Darwinism Today 



By VERNON L. KELLOGG, Professor in the Leland Stanford 

 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 other more im- 

 portant proposed auxiliary and alternative theories of species- 

 forming. 



President David Starr Jordan in The Dial: Its 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 Y<yk 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. 



Locy's Biology and Its Makers 



By WILLIAM 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 

 and index. The 123 illustrations include portraits, many of 

 them rare, of 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 

 II 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.
