 PSYCHOLOGY OF SEX

The book is intended to fill a serious gap in the 

 literature dealing with sex. It aims at giving the 

 important facts about sex, mating, and reproduction, 

 from the physiological and psychological point of 

 view, and it gathers tog-ether for the general reader 

 a vast array of facts which have hitherto only been 

 accessible to the student specialising in the subject. 



" There is a growing consensus of opinion that consider- 

 ably more information should be imparted to young people 

 concerning the relationship of sex. Prohibition is frequently 

 suggestion, and concealment may be fraught with disaster. 

 The impartation of this knowledge is a most delicate task, 

 and this handbook will effectively qualify these upon whom 

 the duty devolves." Christian Commonwealth. 



" It is therefore a real satisfaction to find a sex manual 

 which may be placed with confidence in the hands of any 

 educated person. . . . He has certainly produced the best 

 little manual which we possess in this field." Eugenics
