both sexes; and the colour of the skin is a uniform blackish grey. In height the 
Indian rhinoceros stands from 5 feet to 5f feet at the shoulder. In a male standing 
5 feet 9 inches at the shoulder, measured by General Kinloch, the length from the 
tip of the snout to the root of the tail was 10 feet 6 inches, the length of the tail 
2 feet 5 inches, and the girth of the body 9 feet 8 inches. The length of the horn 
is seldom more than a foot, although Jerdon says that there are instances on 
record of horns of 2 feet in length, and one in the British Museum measures 
19 inches. 
The Indian rhinoceros is further characterised by its teeth. As 
Teetl1 ' a rule, there is but a single pair of broad incisors in the upper jaw, 
although in some cases there may be a smaller pair behind them. In the lower

jaw there is one pair of long, triangular, pointed tusks, and between them a pair 
of small cylindrical incisors which can be of no functional importance. The upper 
molar teeth have tall crowns, and in the absence of a buttress at their front outer 
angle, and the flat plane formed by their worn surface, resemble the one represented 
in the lower figure on p. 464. They are, however, distinguished from the latter 
by the presence of a small vertical plate, projecting from the outer wall into the 
extremity of the middle valley. It will be obvious that this flat plane of wear of 
the cheek-teeth implies that the jaws have a backwards-and-forwards grinding 
motion, and not a champing action; such a mode of mastication being similar to 
that existing in horses and cattle.
