a, the os pubis divided a little to the left of the symphysis ; J, placed close to the 

 upper part of the urinary bladder, upon which lies the vas defei'ens ; c, placed on the 

 upper part of the rectum, near the left ureter ; c', at the junction of the middle and lower 

 parts of the rectum points to the vesicula seminalis ; c", the anus ; d, the urethral bulb ; 

 c, the crus penis divided ; /, the short sacro-sciatic ligament attached to the spine of the 

 iscbium ; 1, common iliac artery ; 2, internal iliac artery ; 3, gluteal artery cut short ; 

 4, common trunk of the sciatic and pudic arteries ; 4', sciatic artery cut as it is passing 

 out of the great sacro-sciatic foramen ; 5, placed on the divided surface of the ischium 

 near the spine, points to the pudic artery as it is about to re-enter the pelvis by the 

 lesser sacro-sciatic foramen 5', the superficial perineal branches of the pudic ; 5", the 

 pudic artery, proceeding to give the artery of the bulb, and passing on to give 6, the 

 artery of the crus penis and the dorsal artery of the penis ; 7, placed on the middle part 

 of the rectum, points to the descending branches of the superior hsemorrhoidal artery ; 8, 

 the superior and middle vesical arteries ; 9, the inferior vesical artery, of considerable 

 size in this instance, giving branches to the bladder, the vesicula seminalis, the rectum 

 (middle hajmorrhoidal), and 9', to the prostate gland.

II. UTERINE AND VAGINAL ARTERIES. 



The uterine artery is directed downwards from the anterior division of the 

 internal iliac artery towards the neck of the utsrus. Insinuating itself be- 

 tween the layers of the broad ligament, it passes upwards on the side of the 

 uterus, pursuing an exceedingly tortuous course, and sends off numerous 

 branches, which enter the substance of that organ. 



This artery supplies small branches to the bladder and the ureter ; and, near its 

 termination, communicates with an offset directed inwards from the ovarian artery. 



Vaginal artery. The vagina derives its arteries principally from a branch 

 which corresponds with the inferior vesical in the male. The vaginal artery 

 descends and ramifies upon the vagina, at the same time sending some
