convinced himself, and proved to the satisfaction of all scientific men, that the cave had been a den of Hyenas[A] at a time when they, as well as Tigers, Elephants, Rhinoceroses, etc., existed in England in as great numbers as they now do in the wildest parts of tropical Asia or Africa. The narrow entrance to the cave still retained the marks of grease and hair, such as one may see on the bars of a cage in a menagerie against which the imprisoned animals have been in the habit of rubbing themselves constantly, and there were marks of the same kind on the floor and walls. [Footnote A: Among the other facts showing that Kirkdale Cave had been the den of these animals, and not tenanted as their home by any of the other creatures whose remains occurred there, were the excrements of the Hyenas found in considerable quantity by Dr. Buckland, and identified as such by the keeper of a menagerie. Any one who may wish to read the whole history of Dr. Buckland's investigations of this matter, showing the patience and sagacity with which he collected and arranged the evidence, will find a full account of Kirkdale Cave and other caverns containing fossil bones in his "Reliquiæ Diluvianæ."] It was evident that the Hyenas were the lords of this ancient cavern, and the other animals their unwilling guests; for the remains of the latter were those which had been most gnawed, broken, and mangled; and the head of an enormous Hyena, with gigantic fangs found complete, bore ample evidence to their great size and power. Some of the animals, such as the Elephants, Rhinoceroses, etc., could not have been brought into the cave without being first killed and torn to pieces, for it is not large enough to admit them. But their gnawed and broken bones attest, nevertheless, that they were devoured like the rest; and probably the Hyenas then had the same propensity which characterizes those of our own time, to tear in pieces the body of any dead animal, and carry it to their den to feed upon it apart.
