162 Notice and Review of the Reliquiae Diluviance. 
ments, many of which he caught up greedily and swallow- 
ed entire : he went on cracking it till he had extracted all 
the marrow, licking out the lowest portion of it with his 
tongue: this done, he left untouched the lower condyle, 
which contains no marrow and is very hard. The state 
and form of this residuary fragment are precisely like 
those of similar bones at Kirkdale: the marks of teeth on 
it are very few, as the bone usually gave off a splinter be- 
fore the large conical teeth had forced a hole through it ; 
these few, however, entirely resemble the impressions we 
find on the bones at Kirkdale ; the small splinters also in 
form and size, and manner of fracture, are not distinguish- 
able from the fossil ones. 1 preserved all the fragments 
and the gnawed portions of this bone, for the sake of com- 
parison by the side of those | have from the antediluvian 
den in Yorkshire: there is absolutely no difference be- 
tween them, except in point of age. The animal left un- 
touched the solid bones of the tarsus and carpus, and such 
parts of the cylindrical bones, as we find untouched at Kirk- 
dale, and devoured only the parts analogous to those which 
are there deficient. The keeper pursuing this experiment to 
its final result ; presented me the next morning with a large 
quantity of album gracum, disposed in balls that agree 
entirely in size, shape, and substance with those that were 
found in the den at Kirkdale. 1 gave the animal succes- 
sively three shin bones of a sheep ; he snapped them asun- 
der in a moment, dividing each into two parts only, which 
he swallowed entire, without the smallest mastication. On 
the keeper putting a spar of wood, two inches in diameter, 
into his den, he cracked it in pieces as if it had been touch- 
wood, and in a minute the whole was reduced to a mass 
of splinters. The power of his jaws far exceeded any an- 
imal force of the kind I ever saw exerted, and reminded 
me of nothing so much as of a miner’s crushing mill, or the 
scissors with which they cut off bars of iron and copper in 
the metal founderies.”” p. 37. 
The plates accompanying Mr. Buckland’s work exhibit 
the various fragments of bone mentioned above, as broken 
by the living hyzna and those found in the Kirkdale cave : 
and really, an inspection of them removes every doubt 
concerning the identity of the cause that produced them. 
We have already spoken of the partial wearing away,
