HYZNA SPELHA 143 
Rhinoceros, and other diluvial animals, occur in a state 
of freshness and perfection, even exceeding that of those 
in the cave at Kirkdale, and from a similar cause, viz., 
their having been guarded from the access of atmospheric 
air, or the percolation of water, by the argillaceous ma- 
trix in which they have been imbedded, whilst other bones, 
that have lain the same length of time in diluvial sand 
or gravel, and been subject to the constant percolation of 
water, have lost their compactness and strength, and great 
part of their gelatine, and are often ready to fall to pieces 
on the slightest touch, and this where the beds of clay and 
gravel in question alternate m the same quarry, as at Law- 
ford. 
“The bottom of the cave, on first removing the mud, 
was found to be strewed all over, like a dog-kennel, from 
one end to the other, with hundreds of teeth and bones, 
or, rather, broken and splintered fragments of bones, of 
all the animals above enumerated; they were found in 
greatest quantity near its mouth, simply because its area 
in this part was most capacious; those of the larger ani- 
mals, Elephant, Rhinoceros, &c., were found co-exten- 
sively with all the rest, even in the inmost and smallest 
recesses. Scarcely a single bone has escaped fracture, 
with the exception of the astragalus, and other hard and 
solid bones of the tarsus and carpus joints, and those of 
the feet. On some of the bones, marks may be traced 
which, on applying one to the other, appear exactly to 
fit the form of the canine teeth of the Hyena that occur 
in the cave. The Hyzna’s bones have been broken, and 
apparently gnawed equally with those of the other ani- 
mals. Heaps of small splinters, and highly comminuted, 
yet angular fragments of bone, mixed with teeth of all 
the varieties of animals above enumerated, lay in the bot-
