 and its effect on the distribution of the 

 national income, voluntary provision 

 against misfortune, charities, poverty, 

 crime, and the inborn qualities and re- 

 cruitment of the population. The reader 

 unversed in statistics will have a new idea 

 when he finishes the book of how illum- 

 inating the statistical treatment of a 

 subject may be. The discussions of 

 official terminology are sometimes divert- 

 ing. Thus the definition of a rural dis- 

 trict as "one under a rural district council" 

 is reminiscent of Sydney Smith's definition 

 of an archdeacon as "a person performing 

 archidiaconal functions." There is an 

 appendix giving the sources of information 

 but no index. 



EPIDEMIC INFLUENZA. A Survey. 

 By Edwin 0. Jordan. 



American Medical Assoc. 

 $5.00 5! x 8|; 599 Chicago 



This treatise is destined to be of great 

 and permanent value as a document in the 

 history of epidemiology. For it is a 

 thorough, sound, critical and comprehen- 

 sive digest of all that is known about the 

 great pandemic of influenza which 

 occurred with such devastating results in 

 1918. Probably no one was so well 

 qualified to undertake this difficult task as 

 Professor Jordan, both because of his wide- 

 ranging knowledge and experience in 

 epidemiology, and his calm and critical 

 judgment. The book is of value not alone 



to the professional epidemiologist; the 

 student of human biology in general will 

 find in it much that is suggestive and 

 useful to him. There is a bibliography 

 covering 52. pages, and detailed author 

 and subject indices.

 The rapid increase of the negro popu- 

 lation in American cities, from 750,000 

 in 1870, to z,ooo,ooo in 1900, and 4,000,000 

 in 19x5, justifies a thorough survey of the 

 environmental factors which affect the 

 negro, and his reactions to them. This 

 survey, made by the Institute of Social 

 and Religious Research, gives the results 

 of studies made in seven northern and 

 nine southern cities. It is concerned 

 chiefly with housing, schools, and recre- 

 ations of the negro and negro neighbor- 

 hoods. A staff of four people, two white 

 and two colored, investigated conditions 

 in these cities, and with the aid of local 

 individuals and organizations amassed 

 considerable pertinent information bear- 

 ing upon the negro problem.

 Dr. Hume has done a real service to 

 epidemiology and preventive medicine, 

 and to human biology generally by 

 resurrecting Pettenkofer's work from the 

 oblivion into which it had almost com-
