144 HY ZENA. 
tom of the den, occasionally adhering together by stalag- 
mite, and forming, as has been before mentioned, an osse- 
ous breccia. Many insulated fragments, also, are wholly 
or partially enveloped with stalagmite, both externally 
and internally. Not one skull is to be found entire; and 
it is so rare to find a large bone of any kind that has not 
been more or less broken, that there is no hope of ob- 
taining materials for the construction of a single limb, and 
still less of an entire skeleton. The jawbones also, even 
of the Hyznas, are broken to pieces like the rest, and, 
in the case of all the animals, the number of teeth and 
of solid bones of the tarsus and carpus, is more than 
twenty times as great as could have been supplied by the 
individuals whose other bones we find mixed with them.”* 
Fragments of jaws were by no means common, but 
Dr. Buckland observed about forty which belonged to 
the Hyena spelea. The greatest number of the teeth 
are those of the Hyzenas and the Ruminant animals. 
Dr. Buckland says, ‘** Mr. Gibson alone collected more 
than three hundred canine teeth of the Hyena, which, 
at least, must have belonged to seventy-five individuals, 
and, adding to these the canine teeth I have seen in other 
collections, I cannot calculate the total number of Hyznas, 
of which there is evidence, at less than two hundred or 
three hundred. 
“The only remains that have been found of the Tiger 
species are two large canine teeth and a few molar teeth, 
exceeding in size those of the largest Lion or Bengal 
Tiger. There is one tusk only of a Bear, which exactly 
resembles those of the extinct Ursus speleus of the caves 
of Germany. 
“In many of the most highly preserved specimens of 
teeth and bones, there is a curious circumstance, which,
