The Perineum. 291 



rest of the spongy portion is about three or three and a 

 half inches long. The prostate gland measures about 

 one inch in length, one and a half inches in breadth, and 

 its base is situated a little above the level of the middle of 

 the symphysis, while its apex rests on the deep triangular 

 ligament and is about one and a half inches behind and 

 below the subpubic angle. 



In the female, the labia -majora correspond to 

 the scrotum in the male and are about three inches in 

 length, meeting, above, at the mons Veneris, and, below, at 

 the fourchette, about one inch in front of the anus. The 

 clitoris corresponds to the penis. The vestibule is a shal- 

 low passage leading to the vagina, while, embracing it by 

 two folds are the labia minora which terminate, posterior- 

 ly, opposite the middle of the vaginal opening. The glands 

 of Bartholini correspond to Cowper's glands in the male 

 and are situated, on either side, behind the bulb of the 

 vestibule, while their ducts, about three-quarters of an 

 inch in length, open opposite the middle of the vaginal 

 orifice. The urethra, about one and a quarter inches in 

 length, is directed upwards and backwards to open into 

 the bladder about three-quarters of an inch behind the 

 middle of the symphysis, and has, in front of it, and at the 

 sides, a venous plexus (Santorini). The urethra is suf- 

 ficiently dilatable as to permit the gradual introduction of 

 the finger. The lymphatics of the external genitals empty 

 into the inguinal glands, whereas, in the neighborhood 

 of the vaginal orifice, there is a neutral "territory at which 

 the vaginal and the vulvar lymphatics communicate. The 

 lymphatics of the perineum terminate in the horizontal set 

 of the inguinal glands. 



Extravasation of Urine. When the mem- 

 branous part of the urethra is ruptured, and urine 

 is extravasated, it will be contained between the super-
