superficial vegetable mould. The remains of the Rhi- 
noceroses, with associated Mammoths and Aurochs, were 
discovered in the deepest part of the basin; but in the 
space of three hundred yards towards the north, it rises 
to the surface and is capped by the gravel. Mr. Brown, 
in concluding his account of the ancient lacustrine basin, 
which formed the grave of the huge pachyderms and 
ruminants that once roamed upon its banks, or wallowed 
in its muddy shallows, says, ‘‘ As the bones and teeth 
which I have now much pleasure in sending you, were all 
collected by myself, I can vouch for their being marked 
correctly, as to locality.” 
The habits of the less robust and less formidably armed 
species no doubt differed from those of the tichorhine 
Rhinoceros, which is more extensively distributed over 
England ; some Naturalists have recognized different ha- 
bits in the three or four species of Rhinoceros now living 
in Africa, and which differ from each other in form and 
structure much less than did the extinct leptorhine and 
tichorhine Rhinoceroses of Europe. 
Although the number of species, now extinct, which 
ranged over the Europeo-Asiatic continent equalled or 
surpassed that of the existing species of Lhinoceros, no 
fossil remains referable to this genus have ever been dis- 
covered in America or Australia. This peculiar form of 
horned Pachyderm appears to have been confined, from 
its first introduction into our planet, to the same great 
natural division of the dry land—the Old World of the 
geographers—to which the existing representatives of that 
form are still peculiar.
