DICOTYLES TORQUATUS. 127 



morsus diaboli a little prominent ; and there was upon each of these 

 prominences a small point that seemed to be hollow, or orifices that led 

 into these bodies. This shows that the female operation is going on 

 without the male, and that the parts are all ready to receive the semen ; 

 and it is most likely that this growth or change of parts is the cause of 

 the desire for the male. It also shows that this animal has but two 

 young at each time. 



I found a swelling or fullness of blood-vessels in each horn. Could 

 this be owing to the female influence having got down so far to be 

 there impregnated by the male ? 



Of the Male Parts 1 . — The penis lies along the belly under the common 

 skin without making any visible ridge, as in the bull, ram, and common 

 boar. The opening of the prepuce is near to the navel, becoming 

 larger near to the opening, as in the boar, but not so large. 



The testicles appear behind, not in a pendulous bag as in the 

 horse, &c, but lie in the perineum, making two tumours, as in the boar 

 and camel. The testicles have a strong tunica vaginalis. The spermatic 

 cord has no tunica vaginalis, which exists in most brutes. 



The bladder is attached to the sides of the pelvis by a doubling of 

 the peritoneum, as the human uterus is; and the ureters and vasa 

 deferentia pass into this fold. The vasa deferentia are united before 

 they join the bladder by a thin membrane, the edge of which is thick 

 like a hem : they enter the urethra at the ' caput gallinaginis ' by di- 

 stinct orifices. 



Behind the bladder, in exactly the place of what are called vesiculse 

 seminales in man, are two fat glandular bodies, irregular on their 

 external surface: their duct ramifies through them, and then passes 

 towards the urethra between the bladder and a small glandular part 

 that is at the termination of the urethra on the posterior or rather 

 upper surface of the urethra in them, and is exactly in the place of 

 that part of the prostate in the human, and [the duct] then enters the 

 urethra close by the openings of the vasa deferentia, but does not com- 

 municate with them. 



That part of the urethra between the bladder and the penis is long 

 as in most animals, and is muscular in its coats. On the sides of this 

 part lie two oblong glands whose ducts open into one canal, which canal 

 opens near the bulb of the urethra. The mucus secreted from these 

 last described glands, is a thick slimy yellowish transparent substance. 



Whether we are to call these prostate or Cowper's glands is hard 

 to say ; or whether what is in the place of vesiculae seminales is the
