Without further discussion of this point, I will only say that it 

 is now pretty clearly established that this Vesicula prostatica is 

 the male sinus genitalis, which, in the female, undergoes a fur- 

 ther development into the vagina and uterus. This, therefore, 

 and not the prostate gland and vesicula seminalis, is the repre- 

 sentative of the uterus. 



Now, in the case of the duplicity of the internal genitalia, we 

 should expect that the bifurcation would occur at the point of the 

 original seat of the organ. This was so in our case, for the vagina 

 connected with the male urethra, at the point of the uterus mas- 

 culinus, between the lobes of the prostate. In the very earliest 

 periods of the foetus, a segmentation of the germ must have 

 occurred at this point, and, thus viewed, it is really no more re- 

 markable than the production of two fingers where there should 

 be but one. 



The interesting points of this case, therefore, are manifold, 

 even as episodes to the chief story of its monstrosity.
