THE FLAT-NOSED RHINOCEROS. 187 
nearly double that of the specimen named Rhino- 
ceros bicornis. These two animals are recognized by 
the negroes and Hottentots, as two very distinct 
species, and are distinguished by them by different 
names. As we have killed ten examples, I have 
had sufficient opportunities of observing the cha- 
racters which distinguish them. They consist 
principally in the form of the mouth, as may be 
verified by comparing the Rhinoceros bicornis and 
the Rhinoceros unicornis with the figure, (PI. XIII.) 
which I have carefully drawn after nature. I 
have named this species Rhinoceros simus. The 
negroes and Hottentots inform me, that it eats 
nothing but grass, while the other species feeds 
on branches of trees and shrubs, — a peculiarity 
which may be inferred from the structure of the 
mouth. The head, when separated from the first 
vertebr®, was of such enormous weight, that four 
men could only raise it from the ground, and eight 
were required to put it into the carriage. The 
flesh of the two species is equally good to eat ; 
and they resemble each other in having a double 
horn, and wanting conspicuous hairs on the skin, 
which distinguishes, at first sight, the Rhinoceros 
unicornis. The following comparative measures, 
taken from adult individuals, killed by ourselves, 
in these countries, will afford a proof of the diffe- 
rence of size : —
