tion at the northern end of the cavern points also to the existence 
of a considerable superincumbent mass of rock. 
The details of the cavern are exactly set forth in the ac- 
companying plan and sections, drawn to scale from careful 
measurements by my son Mr. E. H. Worth. The datum is 17.70 
above Ordnance. 
A review of the whole facts enables us to distinguish between, 
at least, two distinct series of deposits : the open stalagmitic- 
breccia above; the concrete -floor with its ordinary cave-earth 
continuation below. The conditions of the remains in each were 
widely different. Those of the concrete-floor and underlying 
cave-earth were generally casual in occurrence ; had all the appear- 
ance of gradual accumulation ; and, save in the case of smaller 
mammals and birds, yielded nothing approaching to a complete 
skeleton : though there was evidence that portions of bodies, at 
least, had been deposited intact. In the stalagmitic-breccia, on 
the contrary, the remains were chiefly of what had been complete 
skeletons. Again, while deer predominated in the breccia, and 
hog was specially plentiful in the concrete -floor, the breccia 
abounded in remains of young animals, and those of the cave- 
earth were chiefly of mature. 
But the most marked differentation was the fact that the remains 
of the breccia were those of animals which must have found their 
way thither for the most part intact. Many of the bones were 
too fragmentary to allow of the recovery of complete skeletons ; 
but there was very good proof in the majority of cases that such 
skeletons had been present. Bones of individuals were found in 
such intimate association as wholly to forbid the supposition that 
they had been moved since the flesh and integuments had decayed. 
From one cavity, around which the stones had been gradually 
cemented, I took out bones and fragments representing practically 
the entire frame of a deer. A mass of small bones, huddled 
together in a nodule of clay, proved to be the phalanges of a 
wolf, and with them were the teeth of the same animal. In 
several instances both human and infra-human upper and lower 
jaws were found effectively in contact. There was the clearest 
testimony that the members of this part of the ancient charnel 
had been contemporaneous in life, as well as associated in death ; 
and had met one common fate.
