me., therefore, not to represent the uterus, but the hymeneal end 

 of the vagina, practically those parts of the Wolffian ducts 

 which with the urinogenital sinus form, as I have indicated, the 

 lower third of the vagina, 



(e) The ducts known as Skene's ducts in the female urethra 

 are really analogous to the prostatic glands of the male. They 

 do not represent any part of Gartner's canal (Wolffian duct), 

 but are merely prostatic. Of this I have no doubt now. 

 The prostatic glands in the male develop from the urinogenital 

 sinus, and in the female the only prostatic element is to be 

 found in Skene's ducts and the small glandular recesses seen 

 round the urethral meatus. 



I must point out, however, that it will be necessary to 

 examine serial sections of full-time male and female foetuses to 

 determine more exactly the analogues of the seminal vesicles, 

 and the more exact anatomy of the common ejaculatory ducts. 



So far as I have traced the development in the male, the 

 prostatic openings of the ejaculatory ducts are the lower ends 

 of the Wolffian ducts. 



The following ta1)le, modified from Quain, gives shortly the 

 views advanced here as to the male and female genital analogues. 



We may now trace the analogous parts more in detail. From 

 what I have already said it is evident that the analogues of the 

 female and male tract are most definitely settled in the upper 

 portions. The disputed points are mainly as to the lower. 



The fact that tlie analogue of the hymen is the vasa defer- 

 entia termination in the male colliculus seminalis, enables us, 

 by superposition of diagrams of the early foetal organs and fully 

 developed adult ones in sagittal mesial sections, to clearly estab- 

 lish practically all the analogues. Thus from the hymen on along 

 the vestibule to the glans clitoridis, is equivalent to all in the 

 male urethra below the colliculus seminalis ; and if the ventral 

 surface of the male organ were split from this point to the 

 urethral orifice, the female construction would be so far imitated. 

 As to the analogue in tlie female of the vesicular seminales, 1 

 have not been able to settle this to my satisfaction, the best 

 opinion yet advanced being that of Bland Sutton, wlio holds 

 that Skene's tubules represent them. That the ovary and 

 testis are analogues and homologues is evident, but in the
