MARKED as have been the advances during the modern scientific 

 era in our knowledge of woman in respect to her anatomic and phy- 

 siologic peculiarities, her special diseases, and the treatment thereof, 

 many problems yet await solution, some of which are chiefly of 

 scientific interest, others of therapeutic importance. 



In complying with the request of the organizers of this great 

 Congress, I have fully realized the seriousness of the responsibility 

 which I have assumed in restricting myself to the topics which I 

 have selected for your consideration. I have avoided all reference to 

 matters pertaining to the treatment of disease, believing that the 

 presentation of certain fundamental scientific problems would be 

 more in keeping with the aims of this convention. I have also 

 deemed it best to confine myself to a few topics of particular interest 

 or importance, rather than to wander discursively over the entire 

 scientific field open to the gynecologist. Your attention is, there- 

 fore, directed to the following subjects: 



1. The determination of sex. 



2. The structure of the ovary. 



3. The functions of the ovary.
