176 The Rev. Mr. Buckland’s account of Fossil Teeth and 
slightest mark of having been rolled by the action of water. 
A few bits of lime-stone and roundish concretions of chert 
that had fallen from the roof and sides, were the only rocky 
fragments that occurred, with the exception of stalactite. 
About 30 feet of the outer extremity of the cave have now 
been removed, and the present entrance is a hole in the per- 
pendicular face of the quarry less than 5 feet square, which 
it is only possible for a man to enter on his hands and 
knees, and which expands and contracts itself irregularly 
from 2 to 7 feet in breadth and height, diminishing however 
as it proceeds into the interior of the hill. The cave is about 
15 or 20 feet below the incumbent field, the surface of which 
is nearly level, and parallel to the stratification of the lime- 
stone, and to the bottom of the cave. Its main direction is 
E. S. E. but deviating from a straight line by several zigzags 
to the right and left (see PI. XVI. fig. 3. ) ; its greatest length 
is from 130 to 200 feet. In its interior it divides into several 
smaller passages, the extent of which has not been ascer- 
tained. In its course it is intersected by some vertical fissures, 
one of which is curvilinear, and again returns to the cave ; 
another has never been traced to its termination ; whilst the 
outer extremity of a third, is probably seen in a crevice or 
fissure that appears on the face of the quarry, and which 
closes upwards before it leaves the body of the lime-stone. 
By removing the sediment and stalactite that now obstruct 
the smaller passages, a farther advance in them may be ren- 
dered practicable. The half corroded fragments of corals, 
of spines of echini and other organic remains, and the curi- 
ous ledges of lime-stone and nodules of chert that project 
along the sides and roof of the cave, together with the small
