86 YEALM BRIDGE CAVE. 
As therefore I have once before said, Southern 
Devonshire in the immediately preceding epoch to 
the “ Great Deluge,” harboured a race of ravenous

OSSIFEROUS CAVERN AT YEALM BRIDGE. 
In the summer of 1835, having casually heard of 
certain bones, met with in the progress of working 
a limestone quarry at Yealm Bridge, I undertook 
to investigate their. value, and the circumstances 
under which they occurred, the present account 
regarding only the bare facts which obtruded them- 
selves to view. 
Lime-rock abounds at Yealm Bridge, and caverns 
and fissures are not unfrequently disclosed to view - 
during its removal for economical purposes. That, 
on the southern side of the river at this spot, rises 
to a great height; and before its consumption com- 
menced, its bed projected to the banks of the river. 
It was in the upright surface of the rock, that the 
opening or openings of the cave probably formerly 
existed ; but the memory of man can render no 
account concerning these original entrances. I say
