the caves, unless they were larger at former periods than at 
present. 
The second suggestion, however, is reasonable and substan- 
tiated by similar occurrences in various parts of England. 
We know that Yorkshire was inhabited at remote periods by 
the hyaena, bear, tiger, and wolf. That not only do such 
animals always reside in caves, but that their remains have 
always been found in cavernous fissures in a fossil state, as at 
Kirkdale, Oreston, Kent's Hole, Paviland, Brixham, &c. And 
as such habits appertain to the above animals in a wild state, 
where could they be so likely to seek a retreat when roaming 
over the hills and dales of the West Riding of Yorkshire, as 
in the various limestone fissures of Craven. And into these 
recesses the remains of the herbivorous quadrupeds might be 
carried to be devoured at leisure ; and here also the carnivo- 
rous species would live and die, for a long succession of 
years, until they became exterminated by the hand of man, 
and other local causes. 
This conjecture is also rendered probable from the fact, 
that when the caves were first discovered, the skulls and 
bones of various animals were strewed over the floor in con- 
siderable numbers. One person collected as many skulls as 
he could grasp with his two arms. As the bones, however, 
were not considered of value in comparison with the relics 
of human art, they were trodden underfoot, crushed, and 
destroyed. From the communications of Mr. Jackson, and 
from my own identification of teeth and bones, the following 
appears to be a list of the mammalian remains exhumed : — 
Cave Tiger. (Felis Spelcea.) A canine tooth, recognized 
by the late Dr. Buckland, and now in the British 
Museum. — Yictoria Cave. 
European Bear. (Ursus Arctos.) I have seen in Mr. 
Jackson's possession a fine canine tooth, the 
second molar, and a portion of the radius of a bear,
