 THE 



CONTEIPOEARY SCIENCE SeEIES. 



Edited by HAVELOCK ELLIS. 



Illustrated Volumes, containing betweeii 300 aiid 400 pp. 



T^HE CONTEMPORARY SCIENCE SERIES will bring within 

 -■' general reach of the English-speaking public the best that is 

 known and thought in all departments of modern scientific research. 

 The influence of the scientific spirit is now rapidly spreading in every 

 field of human activity. Social progress, it is felt, must be guided and 

 accompanied by accurate knowledge, — knowledge which is, in many 

 departments, not yet open to the English reader. In the Contemporary 

 Science Series all the questions of modern life — the various social and 

 politico-economical problems of to-day, the most recent researches in 

 the knowledge of man, the past and present experiences of the race, 

 and the nature of its environment — will be frankly investigated and 

 clearly presented. 



The first Volumes of the Series a?'e : — 



THE EVOLUTION OF SEX. By Prof. Patrick Geddes 

 and J. Arthur Thomson. With 90 Illustrations, and about 300 

 pages. [Ready. 



*' A work which, for range and grace, mastery of material, originality, and 

 incisiveness of style and treatment, is not readily to be matched in the long 

 list of books designed more or less to popularise science. . . . The series will 

 be, if it goes on as it has begun, one of the most valuable now current." — 

 Scottish Leader. 



"The book is the opening volume of a new Scientific Series, and the 

 publishers are to be congratulated on starting with such a model of scientific 

 exposition." — Scots77ia7i.
