siderable quantity ; and these are generally more entire 
than the bones of the larger animals. Several jaw-bones^ 
with the teeth, have been obtained ; but I have seen no 
entire, cranium, even of these small animals. 
: Of all the rehcs in the cavern, however, those of the 
hyena are the most abundant, the teeth and bones being 
found in great quantities. Not a few entire jaw-bones, 
chiefly of the lower jaw, have been obtained ; and these 
aye very distinctly characterised, as I have observed, on 
comparing them with a recent skull of the hyena, in the 
possession of Mr Atkinson of York. 
Among the mud of the cavern, Professor Bucklanb 
discovered some rounded pieces, or balls, of a whitish sub- 
stance, which he supposes to be the faecal matter of the 
hyenas. This substance, being analyzed by Dr Woll as- 
TON, was found to consist of the same ingredients as the 
dung of dogs that are fed on bones. I have seen some 
specimens of this substance; but having observed some 
pieces of bones nearly in the same state, I am not without 
suspicion, that the whole may be portions of bone^ decom- 
posed in the cavern^ and reduced to their present form by 
a mixture of water and other ingredients. No sand or gra- 
vel, or next to none, has been found in the mud ; yet I 
have procured from it two or three small pebbles. 
Kirkdale Cavern is not the only cavity in the ooHte rocks 
of that quarter, in which such organic remains have been 
discovered. In the year 1786, some workmen, employed at 
a quarry about a mile north-east of Kirkby Moorside, laid 
open a chasm in the rock, several yards below the surface 
of the ground, containing a large collection of bones. They 
were supposed to be the bones of men and horses, whose 
carcases had been thrown into the chasm, after some battle 
fought in the neighbourhood : but as the chasm was com- 
pletely closed above, not by mere alluvial matter, but by
