dugong , two-horned rhinoceros , and tapir of Sumatra. 271 
where villous. The small intestines, which were short, had 
oblong processes from the internal membrane. There was 
no gall bladder, and the kidneys conglomerate, large, and 
flattened, but less so than in the bear. 
In the rhinoceros from Sumatra, which is four feet seven 
inches and a half high at the shoulder, and eight feet from 
the nose to the rump, the oesophagus enters the stomach ten 
inches from its cardiac extremity ; the internal membrane is 
smooth round its great curvature ; from the oesophagus to 
the pylorus five feet nine inches. The extent of the cuticular 
lining is shown in the drawing. In shape altogether the 
stomach is nearer that of the elephant, but in its cuticular 
portion is similar to the horse ; and a bott, in all respects 
the same as those met with in this country in horses, was 
found in it. 
The small intestines measured fifty-four feet six inches ; 
the valvulas conniventes are continued nearly through the 
whole extent, and in general circular, although not all so. 
The caecum is conical, two feet six inches long, one foot six 
inches wide, irregularly honey-combed, and has some of the 
conical processes delineated by Mr. Thomas. The colon and 
rectum are twenty-six feet long. From the termination of 
the longitudinal bands to the anus is eight feet six inches of 
that length. The spleen is long, thin, and flat, two feet long, 
and at the broadest part eleven inches wide. 
The kidneys are conglobate, and rather longer than 
common. 
The heart is short and rounded ; in other respects as usual 
in the class mammalia.
