342 DISSECTION OF THE EABBIT 



in size according to the presence or absence of 

 embryos, and the stage of their development. 

 The two uteri open by separate apertures into 

 the anterior end of the vagina. 



iii. The vagina is a very wide median tube, com- 

 mencing a little ia front of the crests of the 

 ilia, and extending straight back to unite, 

 within the pelvic cavity, with the neck of the 

 bladder, at the commencement of the vestibule. 



c. The vestibule or urino-genital canal is a wide 



^median tube, commencing opposite the hinder 

 end of the obturator foramen, and running back 

 through the pelvic cavity, ventral to the rectum, 

 to the vulva. Its walls are very vascular, and 

 correspond to the corpus spongiosum in the male. 



d. The clitoris is a small rod-like body, corresponding 



to the penis of the male, and lying in the anterior 

 or ventral wall of the vestibule, just within its 

 external opening. It ends in a soft conical body, 

 the glans clitoridis, and is connected with the 

 ischia by two corpora cavernosa similar to those 

 of the male, but of smaller size. 



e. Cowper's glands are small, and lie on the dorsal 



wall of the vestibule, opposite the hinder border 

 of the pelvic symphysis. 



f. The perinaeal and rectal glands are similar to those 



of the male (p. 340). 



SUt up with scissors the vestibule and hinder part of the 

 vagina along one side. Note the great vascularity of the 

 walls, the position and relations of the clitoris, and the open- 

 ing of the bladder into the vestibule. 



Slit up the anterior pa/rt of the vagina along the ndd- 

 ventral line, to expose the openings of the uteri into the 

 vagina. Note the very prominent lips of these openings.
