58 CARNIVORA. 



lion ; the caecum is rather longer, but is similar to that of a lion 1 . The 

 colon and rectum are the same as in a Hon. The liver and gall-bladder 

 are much the same. The kidneys are exactly the same as in the lion 2 . 

 The heart is veiy similar to that of the lion ; also the vessels going off 

 from the curvature of the aorta. 



The eye is like a lion's, having the pigmentum album [tapetum luci- 

 dum] above the optic nerve. The sclerotic coat is thickest at the anterior 

 part. The membrana nictitans is a thick cartilaginous substance in the 

 middle, but is ligamentous on the edges. It is dark on the inside 

 towards the edge, especially the middle space between the two extremes ; 

 it is also black on the external surface. Is this to prevent any rays of 

 light from passing through when the eye is drawn inwards and hidden 

 behind this membrane ? 



The penis is continued along the belly, is easily pulled out of the 

 prepuce, and the prepuce then seems to be continued all along the penis 

 to the end, and much of the same colour. This is not the same as in a 

 dog, and most other animals ; for the penis in them would seem to be 

 a distinct body when pulled out of the prepuce 3 . 



The anus opens externally in a sulcus below, and in the hollow of a 

 semilunar curve of a sidcus that is between the anus and the tail. This 

 sulcus has the opening of a duct into each end, which leads to two bags 

 that he on each side of the anus. These bags are larger than a hen's 

 egg, are pretty round, and contain a yellow substance somewhat harder 

 than common butter, which smells like musk. They are always distended 

 with this matter, and but very little of it can escape in substance. It 

 would seem as if it was only meant as a smelling bottle 4 . 



Of the Female parts of Generation. — Below the anus opens the vagina ; 

 there are no external lips ending in a projecting point, as in many other 

 animals, but a round hole similar to an anus. Just within this is the 

 clitoris, which points forwards like a short blunt tongue. The common 

 vagina is but short, about 1| inch long : the proper vagina is about 

 5 inches long, of a livid colour, and has a vast number of loose folds or 

 rugae running in the direction of the vagina. Near the os tincae, on 

 that side next the bladder, there is a process or a flat pyramidal 

 minence which has a small loose floating body attached to its apex 

 about an inch long 5 .
