THE 
CONTEMPORARY SCIENCE SERIES. 
EpireD By HAVELOCK ELLIS. 
Most of the Volumes are illustrated, and contain between 300 and 400 pp. 
Others to follow at short intervals. 
HE CONTEMPORARY SCIENCE SERIES brings 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—are 
frankly investigated and clearly presented.
