40 Sir Everard Home on a new species of rhinoceros 
of different lengths in the British Museum, and one forty- 
two inches ; a drawing of which is annexed. 
In this skull it will be seen, that the horns differ in many 
particulars, from those belonging to the other recent species 
of the rhinoceros. The long one is placed upon the extremity 
of the nasal bones, with a direction nearly straight forward, 
and the smaller one so close behind it, as to appear intended 
for a support to its base. These striking differences would 
be of little importance, were it not that they make it bear so 
close a resemblance to the fossil skull from Siberia, as to 
leave no prominent characteristic mark between them ; and 
were it not that the one is in a fossil state, and the other 
recent, they would be decided to belong to the same species; 
for although there is no horn attached to the fossil skull, the 
surface fitted for it is obviously marked, and no error can be 
committed, respecting its situation, or direction. The drawing 
is made from a fossil skull, sent over by the Emperor of 
Russia to Sir Joseph Banks, and deposited in the British 
Museum, and compared with another, which came to this 
country, but was afterwards sent to France. The skull is 
thirty-three inches long ; the largest of the recent rhinoceros 
in the collection of the Royal College of Surgeons, is two feet. 
The drawing of the skull from Siberia is so accurate, as 
to make a description of its external appearance unneces- 
sary ; it is however proper to add, that all the fossil skulls 
that have been examined, are alike, and three feet long ; 
so that we have now acquired a nearer approach to the form 
of the skull of the rhinoceros of former ages, in that which 
is represented in these drawings, and is here described, than 
has before been obtained. From this fact, so completely
