external [outer and inner] ones are smaller and resemble each other in 

 shape, size, and exactly oppose each other. The hind foot has five 

 claws ; the middle one is the largest and the longest, the next on each 

 side are a little shorter, but resemble each other ; the two outer [outer 

 and inner] ones are much smaller, but are also alike. The ears are 

 nearly 2 inches in length, and are covered with a scaly cuticle. The 

 nose terminates in a flat surface like a hog's, on which open the nostrils, 

 and the anterior part has a projecting edge. The under jaw is shorter 

 than the upper, and has considerable motion and strength. There are 

 no teeth in the anterior parts of the mouth in either jaw. The tongue 

 is exceedingly long ; round on the under surface, but more flat on the 

 upper ; it is conical, and terminates in a point 1 . 



On each side of the anus there is a gland, whose duct is large, and 

 opens externally by a large orifice 2 . The penis in its relaxed state is 

 about 2 inches in length, has no sheath or prepuce, terminates in a 

 point, and appears to have no glans, the ends of the corpora cavernosa 

 making two nipple-like processes about half an inch from the point or 

 end of the penis. There are four nipples ; two on the lower part of 

 the belly between the thighs, and two upon the breast. 



The stomach is pretty globular ; the oesophagus enters pretty near 

 the pylorus, so that the hollow curvature is but small or short. The 

 pylorus is loose, not bound down to the back as in the human subject. 

 The duodenum has a pretty broad mesentery, and so has convolutions : 

 it passes to the left, behind the mesentery, being connected to the pos- 

 terior part of the root of the mesentery, but is exposed through its 

 whole course ; it gets on the left edge of the mesentery, and becomes a 

 loose intestine, forming jejunum and ileum. At the lower part of the 

 belly it enters the colon, or rather dilates into colon, which passes up 

 on the right side, attached to the right edge of the mesentery, at the 

 root of which it is more closely connected ; it then crosses the spine, 

 having a mesocolon of its own, passes down on the left side, and forms 

 the rectum, which terminates in the anus ; on the sides of which are 

 two bags, or rather two large ducts or glands, which open just by the 

 verge of the anus, and which glands secrete a fetid musk or rather 

 castor-like mucus : its internal surface is covered with small glands. 

 In both mesentery and mesocolon there were a number of lymphatic 

 glands. The great epiploon is attached to the stomach on its fore part, 

 and to the pancreas behind, on the left to the spleen, and on the right 

 to the beginning of the duodenum. The small epiploon is connected
