of the great cave ; and the water, laden with sediment, entering from 

 time to time, might have elevated the layers of matted bone and all 

 the scattered remains on the surface, while the current was insuffi- 

 cient to disturb the stones or to affect, to any extent, the deposit of 

 former floods. The buoyancy of the organic remains is not required 

 to be greater by this hypothesis than is demanded by that of their 

 having been introduced by a current through the swallow-holes. 



But if water introduced the red earth, it is certain that it had 

 nothing to do with the introduction of the stones. As the red 

 calcareo-magnesian cement of the dolomitic conglomerate supplied 

 the red earth, so did its imbedded pebbles of limestone supply the 

 latter. Either angular or water-worn, they are in the same state 

 as they were w T hen they formed integral parts of the roof, sides, and 

 floor of the cave, with the exception that they have been worn by 

 carbonic acid, and exhibit a network of calc-spar, stems of Crinoids, 

 and shells of Spirifers in strong relief. It is needless to repeat that, 

 had they been once set in motion, these organic remains must have 

 been ground to powder. 



B. Special Description. 



1. Jaivs and Teeth of Carnivora. — I shall pass on now to a brief 

 consideration of the jaws and teeth, omitting, for the sake of brevity, 

 all mention of the bones. Amongst the Carnivora *, Felis spelcea is 

 represented by four teeth of the molar series, and six canines. As 

 the difference in the length of the crown of the large upper canine 

 as compared with the largest of the lower ones (1-1 inch) is greater 

 than the difference in an adult tiger (0-4), these teeth may indicate the 

 presence of two species. This difference is, I think, too great to be 

 owing to mere sexual peculiarities. There is no evidence as to 

 whether they belonged to the Lion or the Tiger ; for P.M. 3, in 

 its size, approaches the corresponding tooth of Felis tigris ; in the
