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 o'ther more im-

President David Starr Jordan in The D'ml: — 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 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.
