DISCOVERED AT KIRKDALE, IN YORKSHIRE. if 
great as could have been supplied by the individuals whose other 
bones we find mixed with them. 
Fragments of jaw bones are by no means common; the greatest 
number I saw belong to the deer, hyaena, and water-rat, and retain 
their teeth; in all the jaws both teeth and bone are in an equal state 
of high preservation, and show that their fracture has been the effect of 
violence, and not of natural decay. I have seen but ten fragments of 
deers’ jaws, and about forty fragments of those of hyaenas, and a still 
greater number of those of rats. (See Plate III. fig. 3, 4, 5, and Plate 
IV. fig. 2 , 3 .) The ordinary fate of the jaw bones, as of all the rest, 
appears to have been to be broken to pieces and swallowed, the teeth 
being rejected as too hard for mastication, and without marrow. 
The greatest number of teeth are those of hysenas, and the rumi- 
nantia. Mr. Gibson alone collected more than 300 canine teeth of 
the hyaena, which at the least must have belonged to 75 individuals, 
and adding to these the canine teeth I have seen in other collections, 
I cannot calculate the total number of hyaenas of which there is evi¬ 
dence, at less than 200 or 300. I have already stated, that many of 
these animals had died before the first set, or milk teeth, had been 
shed; these teeth are represented in Plate VI. fig. 15 to 27 : the 
state of their fangs shows that they had not fallen out by absorption. 
The only remains that have been found of the tiger species (see 
Plate VI. fig. 5, 6, 7) are two large canine teeth, each four inches 
in length, and a few molar teeth, one of which is in my pos¬ 
session ; these exceed in size that of the largest lion or Bengal tiger. 
There is one tusk only of a bear (see Plate VI. fig. 1), which 
exactly resembles those of the extinct ursus spelaeus of the caves of
