QUADRUPEDS. 277 



PaljEOTHeeium. The large tooth, Fig. 6, PI. XVII, agrees so 

 well with the description of the middle grinders in the lower jaw of 

 this fossil animal, given by Mr. Parkinson, Vol. 111. p. 382, 38.3, that 

 we cannot assign it to any other. The outer surface shews two por- 

 tions of cylinders, and the masticating surface, as well as the inner 

 surface, shews the form of the letter W. The masticating surface is 

 above two inches long; and hence the species must be the palcBotJie- 

 rium magnum. No. 7, if not belonging to the rhinoceros, may be an 

 tipper grinder of the same animal ; having the surface nearly square, 

 with the same appearance of two cylinders on the outside, and of the 

 letter W on the upper and inner surfaces. No. 8 has the same charac- 

 ters; but being much smaller, may be ascribed to a lesser species of 

 palaeotherium. The remains of this extinct animal have hitherto been 

 discovered only in France. 



No. 11, PI. XVII, is part of a jaw with two grinders, of some 

 unknown animal, about the size of a horse. The teeth are remarkably 

 smooth, and nearly quadrangular on the upper surface; which, in the 

 largest, measures one inch by three quarters. 



No. 5 is a crural bone of an animal about the size of a hare, but 

 with shorter and stronger legs. — No. 16 is a fragment of a rib, be- 

 longing to some animal about the size of a weasel. 



No. 3 is a fragment of a hollow bone, of a very singular descrip- 

 tion, being the only fossil relic which we can assign to any of the 

 feathered tribes. Small as the fragment is, its character is so well 

 marked, particularly in its thinness, compactness, and translucency, 

 that we do not hesitate to consider it as part of a pinion bone of a 

 fowl, of the size and form of a goose, or a duck. 



It is observable, that we have not seen, or heard of, any entire 

 cranium found in the cavern ; and few vertebrae and ribs have been 

 met with. Among other specimens, we have examined dm astragalus, 

 or heel bone, greatly resembling that of a hare, but vastly larger ; 

 and some blade bones like those of the ox.
