and without making his book dry reading. 

 He has, as he explains in his introduction, 

 confined himself to an exposition of facts, 

 without any attempt at imaginative 

 reconstruction of prehistoric life or men- 

 tality. The example might profitably be 

 followed by other writers of science for 

 the layman. 



CONTEMPORARY SOCIOLOGICAL 

 THEORIES. 



By Pitirim Sorokin. Harper and Brothers 



$4.00 5I x 8^.; xxiii + 785 New York 

 Professor Sorokin has here done a 

 useful piece of work. He has classified 

 all of the more important sociological 

 theories that have existed for the last 

 sixty or seventy years and has critically 

 analyzed the fundamental principles under- 

 lying each. The book contains an enor- 

 mous amount of data and has a large 

 bibliography. The human biologist will 

 find it a handy reference source, though 

 he will probably not always agree with 

 the author's position. 



JEWISH COMMUNAL SURVEY OF 

 GREATER NEW YORK. First Section: 

 Studies in the New York Jewish Population. 

 Bureau of Jewish Social Research 

 50 cents 6 x 9; v -f- 45 (paper) New York 

 An interesting statistical survey of the 

 Jewish population of Greater New York 

 showing: — 1. Movement of Jewish popu- 

 lation in New York City. z. Age distribu- 

 tions, births and deaths. 3. Causes of 

 deaths among Jews. In 192.5 there were 

 1,750,000 Jews in New York City, and the 

 number increased 16.4 per cent between 

 1916 and 19x5. In both years they made 

 up about 30 per cent of the total popula- 

 tion. 



L'ETHNOLOGIE DU BENGALE. 

 By Biren Bonnerjea. Paul Geuthner 



40 francs Paris 



7§ x 9§ ; xxiii +169 (paper) 

 The author of this book has, as he 

 acknowledges, undertaken an almost im- 

 possible task. He has attempted to cover 

 the entire subject of the ethnology of 

 Bengal; and in consequence his book is 

 nearly as difficult to read as a dictionary. 

 This is not to say that he has written a 

 bad book, but that his book is useful 

 primarily for reference.

Summary reports for twenty-seven coun-

 tality, Infant Mortality, Health Organiza-

Good brief statements, not in general 

 detailed enough to tempt the reader to 

 statistical research on the data given.
