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 

 horns of 2 feet in length, and one in the British Museum measures 



record of 

 19 inches. 



The Indian rhinoceros is further characterised by its teeth. As 



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.
