RODENTIA. 



by a very large opening, so large that the testicle could be pushed into 

 the abdomen if it did not adhere at the lower end, all along the 

 posterior part of the testicle and spermatic chord. The attachment of 

 them to the tunica vaginalis is by a thin and pretty broad membrane. 

 The vasa deferentia are pretty large, and, where they pass behind the 

 vesiculae seminales, they become very large, like the swell in a Florence 

 flask ; they then enter the vesiculse seminales very near the opening of 

 them into the urethra, not one -tenth of an inch from it. 



There is only one bag, or vesieula seminalis, for both vasa deferentia ; 

 it is pretty large, somewhat oblong and flattened, as if it was flattened 

 by the weight of the bladder. It seems to be smooth on its inside, is 

 very thin in its coats at the fundus, but becomes thicker towards its 

 apex, which thickness is an additional gland having its ducts opening 

 into the urethra ; but this gland seems to be distinct from the prostate, 

 and is of a much more spongy nature, and goes round the beginning of 

 the urethra. The duct, or rather the opening of the vesieula seminalis, 

 is very large. "What I take to be the prostate glands are two on each 

 side of the urethra in the membranous part, just before the other de- 

 scribed : they are but small and pretty compact, and the duct enters 

 the urethra about the middle of the membranous part ; but these may 

 be Cowper's and the other the prostate upon each side of the urethra. 

 Between these last glands and the bladder there is a plexus of veins 

 which are filled by the vena magna in dorso penis. The urethra is very 

 large through its whole length, but especially at the bulb, where it 

 would admit one's finger. The penis is of a pyramidal figure when not 

 injected ; the cavernous part is very strong, being chiefly in parallel 

 tendons. The hare is retromingent : for the penis almost points back 

 to the anus. The penis after being injected with quicksilver is of the 

 figure of an S, and the point is turned or curved backwards much more 

 than before injection. 



Upon each side of the penis there is a glandular body much larger 

 than a pea, having an orifice in its middle which leads to its centre, 

 something like a sebaceous gland filled with a pretty firm substance. 

 Immediately between them and the rectum there is a hollow cavity 

 whose opening is nearly as large as the cavity itself : this gland lies 

 just at the mouth of it, or in other words makes a part of its mouth. 

 This hollow is upon each side of the perineum, which is a very thin 

 part, uniting as it were the hollow curve of the penis backwards to the 

 anus like a fraenum 1 . 



The anus goes a considerable way further under the tail than the
