THE RABBIT. 323 



pinkish projections, the Graafian follicles, each of which 

 contains an ovum. 



XXXI. Cut through the symphysis pubis, and dissect 

 away the urinogenital organs from the body, fasten 

 them with the dorsal side upwards, and make out 

 the rectal and perineal glands, which have the 

 same relation as in the male (see 276 and 277) ; 

 then remove these glands along with the rectum, 

 and make out 



292. The vestibule (Fig. 62, B, vb), a wide tube, with 

 the dorsal wall of which the rectum was in contact : with 

 its anterior end the bladder and vagina are connected, 

 while, posteriorly, it opens externally by the vulva. It- 

 has precisely the relations of the urethra of the male ( 265), 

 and its walls are invested with a vascular tissue answering 

 to the corpus spongiosum (.279). 



293. Cowper's glands (c.gt), a pair of small whitish masses, lying 

 on the dorsal wall of the vestibule at about the middle of its length. 



XXXII. Turn the organs with their ventral side 

 upwards, make a median longitudinal incision 

 through the vestibule, and continue it forwards 

 until the cavity of the bladder is exposed : make 

 a median longitudinal incision through the ventral 

 wall of the vagina : afterwards slit up one of the 

 uteri and the corresponding Fallopian tube along 

 their whole length. Make out : 



294. The small aperture of the ureters in the dorsal wall 

 of the bladder about half way between its fundus and 

 its neck. 



295. The almost insensible passage from the bladder to 

 the vestibule, the neck of the former being very wide. 



296. The irregular rugae or ridges of mucous membrane 

 into which the walls of the vestibule are raised.
