the lower jaw, they differed in size, and probably in form, 

 from those of the living species. 



The head of the rhinoceros brought to this country by 

 Mr. Campbell, differing in the form and size of its horn from 

 the common African rhinoceros, renders it desirable that it 

 should be ascertained how far it agrees in character with 

 the head of the fossil rhinoceros. The head of the fossil 

 animal, as is shown above, differs from the bicorn of Africa, 

 in having a considerable space between the bases of the two 

 horns ; and Mr. Campbell, with a due attention to correct- 

 ness, states, " The common African rhinoceros has a 

 crooked horn resembling a cock's spur, which rises about 

 nine or ten inches above the nose, and inclines backward ; 

 immediately behind this is a short thick horn ; but the head 

 they brought had a straight horn projecting three feet from 

 the forehead, and about ten inches from the tip of the nose. 

 The projection of this great horn very much resembles that 

 of the fanciful unicorn in the British arms. It has a small 

 thick horny substance eight inches long, immediately behind 

 it, which can hardly be observed on the animal at the 

 distance of one hundred yards." 



It appears, therefore, that the newly discovered head 

 of the African bicorn agrees with the common African 

 bicorn, and differs from the fossil species in not having the 

 space between the horns.* 



Pallas found many of these fossil remains in Siberia, 

 and, particularly a complete rhinoceros, still covered by its 

 skin, and buried in the sand on the borders of the river 

 Wiluji. Hence Cuvier infers, that this unknown animal 

 had not been brought from afar, nor had ceased to exist by 

 any slow, but by some sudden, change of the earth. How
