I. INTRODUCTION 



In view of the occasional conditions of hermaphroditism or 

 pseudohermaphroditism, especially among mammals, wherein 

 certain organs or tissues characteristic of both the male and the 

 female occur in the same animal, and in view of the observations 

 of Prof. F. R. Lillie on the development of the free-martin, and 

 especially after the work of Steinach and others on the trans- 

 plantation of gonads from one sex to the opposite one, there is a 

 decided tendency to assume that one sex gland exerts a deleterious 

 influence upon the other, perhaps through the mediation of an 

 internal secretion from the gland. Various degrees of an inter-
