a right fibula, some ribs, and the atlas and axis vertebrae of 
a bear were found by Mr, William Hinchley. These bones 
have also been most carefully compared by Dr. Carte with 
bones of the Ursus spelaous and maritimus, and he is of 
opinion that they are identical with the bones of the last 
animal. As the acquisition of a new species is always an 
interesting circumstance, and more especially as the Polar 
bear has never hitherto occurred in Britain, or even in 
Europe, in a fossil state, it is the more to be regretted that 
a skull has not been found, as the diagnosis of the maritimus 
would have been more satisfactory and decisive in that 
portion of the skeleton than from the bones of the extremities 
alone. The removal of all semblance of doubt on the question 
is the more essential, as this species will prove one of the 
most important additions made to our Fossil Fauna for many 
years, and, with the Musk Ox, go far to prove that instead of 
this country having cooled down from that of a tropical 
climate, it has been gradually increasing in temperature 
since the Glacial Epoch, as we have now three decidedly 
boreal quadrupeds, the Rein Deer, Musk Ox, and Polar 
Bear ; besides the Moose Deer, which is also a northern 
species. 
During the autumn of last year, I was indebted to the 
kindness of Mr. J. Glennon for the loan of the two fine 
crania previously alluded to, and finding upon close ex- 
amination that they presented a difference of conformation 
much greater than, I conceive, could be expected to result 
from age or sexual distinction merely, as both have evidently 
belonged to adult individuals, I propose to point out such 
characters as appear to me sufficient to mark them as 
belonging to two distinct species of bears. The most 
striking difference observable on looking down upon the two 
skulls in juxtaposition, is not only the disparity in size and 
the much greater entire length of one than the other, but
