86 CARNIVORA. 



pancreatic duct enters with it by one orifice ; and, indeed, they unite 

 some "way before they enter. The situation of the kidneys is as in a 

 dog, viz. the left is lower than the right 1 . 



The angles of the eyelids are very oblique ; the external upwards, 

 the internal downwards. There are two sets of muscles [to the eye- 

 ball], as in the lion. The iris has the nigrum pigmentum on the anterior 

 surface as well as the posterior, but not so thick. The choroid is like 

 the monkey's, and has two veins on it like the lion's : it has an album 

 pigmentum, the lower end of which comes a little lower than the optic 

 nerve. The crystalline [lens is] equally convex on each side. 



Male Organs of Generation. — The testicles are situated as a dog's. 

 There is not a very strong cremaster: the tunica vaginalis does not 

 communicate with the abdomen, but is continued a pretty way up 

 the spermatic cord. There are no vesiculae seminales ; but the vasa 

 deferentia enter, as in man, in the middle of the prostate gland : this is 

 pretty large, but does not make, as it were, a part of the bladder ; so 

 that the bladder has a kind of neck between the prostate and bladder. 

 The membranous part of the urethra is long and covered by a thru 

 muscle. 



The penis has a bone of a peculiar figure, the end of which makes 

 the glans, and is covered over by a thin membrane that is attached 

 about half an inch from the end, and is not perforated anywhere. The 

 corpus cavernosum goes no further forwards than the glans on the 

 bone, which is about 2 inches. The corpus spongiosum begins as in 

 man and passes forwards along the body of the corpora cavernosa, then 

 along the lower surface of the bone, and about 2 inches from the end of 

 the bone it surrounds the bone. There are the same muscles as in 

 man; besides them there are two pairs. One pair arises from the 

 hollow of the sacrum, spreads on each side of the rectum as they pass 

 on, and are mostly lost there ; but a small portion passes under the 

 bulb of the urethra, and between the two portions of the sphincter ani 

 that are attached to the bulb ; from thence they are continued along 

 the under surface of the urethra. In another racoon they seemed to 

 cross the erectores penis, to get on the upper side of the penis, and to 

 be lost in it where the urethra begins to surround the bone : they seem 

 to raise the anus and bring back the penis. The other pair arise from 

 the under surface of the tail, passing upwards between the two levatores 

 ani ; they are spread on the posterior surface of the rectum, seeming to 

 bring the anus down. Cowper's glands could not be found. 



Female Parts of Generation. — They are in every respect the same as
