in her wallow. These animals in their natural state live 
almost exclusively on the leaves and the smaller branches 
of trees, such as the various species of fig, and the jack- 
tree ; and, here, their taste as far as possible is consulted, 
but it is found to be a costly one, as jack and fig-trees are 
not easily purchased, so that their food has to be supple¬ 
mented with grain. 
At present there are no examples in the Gardens of 
either of the two Asiatic species of one-horned Rhino¬ 
ceroses, but as the Garden has already had both species, 
and as the Committee are making efforts to obtain other 
specimens, it may be as well to indicate here their leading 
external characters and distribution. There has been a 
misapprehension in the past regarding the relative size 
of these species, as they have been spoken of as the 
Greater and the Lesser one-horned Rhinoceroses ; this, 
however, is incorrect, as both the species apparently attain 
similar dimensions. The most striking external charac¬ 
ters separating the two are the size of the ears, as 
already mentioned, and the difference between their 
hides, and this latter feature is very marked. 
The Rhinoceros from the Bengal Sundarban has its hide 
covered over most regularly with a mass of closely-set 
tubercles, this being the species which has the smaller ears 
and which is supposed to be the Lesser Rhinoceros, and 
identical with R . sondaicus of Java and the adjoining 
islands ; whereas the other rhinoceros, that is, R. uni¬ 
cornis, the true Indian Rhinoceros, has its hide covered 
with tubercles, but instead of being closely set together 
and uniform in size, they are generally separated from 
one another except on the limbs, and vary much in size, 
those on the hind quarters being very large. There is
