ern world with their dour philosophy the 

 only books about It were humorous ones. 

 This is a sound attitude, as Dr. Clendening 

 has lately emphasized. So far as may be 

 judged from historical and general litera- 

 ture, sexual apathy and coldness is a 

 modern phenomenon. Mr. Gallichan 

 says the usual things about its being 

 due to inadequate education of girls in 

 sex matters, to lack of understanding on 

 the part of men, to the complexity of 

 modern life, etc. We have looked in vain 

 for anything in the way of an original 

 note in the book.

 This section of the Baur-Hartmann 

 handbook of genetics deals with the 

 problem of sex in plants, by the foremost 

 living authority in this field. It main- 

 tains the high standard set by the other 

 parts of this great undertaking which have 

 so far appeared. There is a bibliography 

 covering nine pages. 



CONTRACEPTION (Birth Control}. Its 

 Theory, History and Practice (second edition). 

 By Marie Carmichael Stopes. 



John Bale, Sons and Danielsson, Ltd. 

 15 shillings London 



5I x 8|; xxvi -f- 480 

 This new edition of Dr. Marie Stopes* 

 vade-mecum for newly weds still embodies all 

 the author's well-known enthusiasm for 

 more and better sex life in the home. In 

 fact the book is not basically altered from 



the first issue. About 60 pages of new 

 material have been added, but the growth 

 between the first and second editions has 

 been intersusceptive. The book cannot 

 legally be imported into this land, 

 quaintly said to be "of the free." Regi- 

 nald, the Office Boy, says he found our 

 copy on the doorstep one morning. 



PSYCHOLOGY AND BEHAVIOR 



SPEECH. Its Function and Development. 

 By Grace Andrus de Laguna. 



Yale University Press 

 $5.00 New Haven, Conn. 



5I x 8f ; xii + 363 

 A thorough-going attempt at a reason- 

 able solution of an extremely difficult and 

 complex problem, the origin of speech. 

 The first part of the book is devoted to 

 the development of the thesis that speech 

 began when man's ancestors came down 

 from the trees and began to hunt on the 

 ground. Its origin was in the animal cry 

 "in order to meet the demands of expand- 

 ing group life. ' ' 



The evolution of language, marked by the differ- 

 entiation of the proclamation, which prepares but 

 does not precipitate response, and of the supple- 

 mentary command, with its power to initiate and 

 control particular acts, is an essential condition for 

 the complex and varied cooperation that is involved 

 in human hunting. 



The second part of the book attempts 

 to trace the evolution of thought which 

 paralleled that of speech. A theory of 

 the origin and development of the naming 

 of objects is developed. The third part 

 of the book recapitulates the preceding 

 arguments from the objective point of 

 view. 



The book is a valuable contribution to 

 the literature of human biology.
