poses the same division of species to be evinced as appeared by the head 

 and jaws. 



From the strictest comparison of the rich collection of these fossil bones, 

 to which he had access, with each other, and with the skeletons of 

 existing species of bears, M. Cuvier considered himself authorized to 

 make the following conclusions : 



1. The bones which are most commonly found in these caverns, exa- 

 mined each separately, belong to the genus Bear. 



2. The skulls, and some of the large bones, present such differences as 

 should induce us to consider them as proceeding from species of bears 

 different from those which naturalists have hitherto described. 



3. These skulls and some of the large bones, the os humeri and fe- 

 moris for example, differ sufficiently among themselves to allow us to 

 believe that the bones of two different species of bears have been here 

 confusedly buried together. 



4. Some of the bones of one of these species are more like to those of 

 the bears of the present day than those of the other. There are even 

 bones, among those of the one, as the os humeri, &c. which are not to 

 be distinguished, if seen by themselves, from those of the common bear. 

 There are others, in both species, which appear to be thus circumstanced, 

 as those of the carpus, &c. 



5. But the skulls are sufficient to furnish such characters as leave no 

 reasonable doubt; and as those fossil skulls, which have the fore- 

 head tumid (bombc), appear to be separated from our common bears 

 more than the fossil skulls with a flat forehead, it is natural to refer to 

 the former those fossil bones of the limbs which differ in the same degree 

 from their analogues in our common bears. The bones of the body or 

 limbs, which more resemble those of these latter animals, are more 

 safely referable to the species with a flat forehead. 



But to complete our knowledge of the skeleton, as M. Cuvier ob- 

 serves, it would be necessary to have all the bones of each species, which 

 at present is not the case, we only having, under two forms, the skull,
