THE BONK CAVES OF THE PLYMOUTH DISTRICT.

nients of long bones ; fragments of jaws of the horse containing 
teeth ; numerous loose teeth ; portions of long bones, and two 
caudal vertebrae; likewise portions of a deer's jaw containing 
teeth. . . . The vertebra of a whale much rounded were also 
discovered, with undeterminable portions of ribs."* "The quantity 
of fragments of leg bones amounted to several bushels, being 
exceedingly fragile, and deprived of their animal matter; the 
whale's vertebra and bear's tusks appeared much worn, as if by 
long-continued friction in water. "f 
Now it is clear that the bulk of the bones could not have been 
roughly used after deposition, however much some of the examples 
might have been. It is clear also that as the bones were found on 
the beach and not in it, they were placed there subsequently to 
the origin of that marine deposit. How can they be accounted 
for more simply than by the hypothesis that they came from 
a pre-existing ossiferous fissure or fissures, precisely analogous in 
character to those at Oreston^J Dr. Moore speaks of " nearly the 
entire collection of bones " as " similar to those formerly obtained 
from the limestone caverns of Oreston, Yealm Bridge, Kitley, and 
Kent's Hole."§ He does not mention the hyaena, but it is included 
among the specimens from the Hoe deposited in our Museum by 
him ; and as some bones in the collection were labelled " from the 
Hoe fissures," it seems probable that there were other discoveries 
beside those of the raised beach, though in all likelihood at much 
the same date. 
That bones should find their way from the fissures to the ancient 
beach is nothing wonderful. The tooth of a rhinoceros was found 
by Mr. Hearder on the present beach " at the entrance of the cave 
under the Hoe .... rounded by its exposure to the tide which 
now flows into it."|| Mammoth teeth have been found here under 
similar conditions.
