out. This bony rock has been dug into in different places, 
and every where undoubted proofs have been met with, that 
its bed, or this osteolithical stratum, extends every way far 
beneath and through the limestone rock, into which and 
through which these caverns have been made, so that the 
queries suggesting themselves about the astonishing numbers 
of animals buried here confound all speculation. 
Along the sides of this third cavern there are some nar- 
rower openings, leading into different smaller chambers, of 
which it cannot be said how deep they go. In some of them, 
bones of smaller animals have been found, such as jaw-bones, 
vertebras, and tibiae, in large heaps. The bottom of this cave 
slopes toward a passage seven feet high, and about as wide, 
being the entrance to a 
Fourth cave , 20 feet high, and 15 wide, lined all round with 
a stalactical crust, and gradually sloping to another steep de- 
scent, where the ladder is wanted a second time, and must be 
used with caution as before, in order to get into a cave 40 feet 
high, and about half as wide. In those deep and spacious 
hollows, worked out through the most solid mass of rock, you 
again perceive with astonishment, immense numbers of bony 
fragments of all kinds and sizes, sticking every where in the 
sides of the cave, or lying on the bottom. This cave also is 
surrounded by several smaller ones ; in one of them rises a 
stalactite of uncommon bigness, being four feet high, and eight 
feet diameter, in the form of a truncated cone. In another of 
those side grottoes, a very neat stalactical pillar presents itself, 
five feet in height, and eight inches in diameter. 
The bottom of all these grottoes is covered with true animal 
mould, out of which may be dug fragments of bones.
