436 Rev. Mr. Buckland’s Account of Fossil Teeth and [Ave. 
schert that had fallen from the roof and sides, were the only 
zocky 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 perpen- 
dicular face of the quarry less than five 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 two to 
seven feet in breadth and height, diminishing, however, as it 
roceeds into the interior of the hill. The cave is about 15 or 
90 feet below the incumbent field, the surface of which is nearly 
Jevel, and parallel to the stratification of the limestone, and to 
the bottom of the cave. Its main direction is ESE. but deviat- 
ing from a straight line by several zigzags to the right and left 
(Pl. XLV. fig. 3); its greatest length is from 150 to 200 feet. 
In its interior it divides into several smaller passages, the extent 
of which has not been ascertained. 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 termi- 
nation; while the outer extremity of a third is probably seen im 
a crevice or fissure that appears on the face of the quarry, and 
which closes upwards before it leaves the body of the limestone. 
By removing the sediment and stalactite that now obstruct the 
smaller passages, a further advance in them may be rendered 
practicable. ‘The half corroded fragments of corals, of spines of 
echini and other organic remains, and the curious ledges of lime- 
stone and nodules of chert that project along the sides and roof 
of the cave, together with the small grooves and pits that cover 
great part of its interior, show that there was a time when its 
dimensions were less than at present; though they fail to prove 
by what cause it was originally produced. ‘There are but two or 
three places in which it is possible to stand upright, and these 
are where the cavern is intersected by the fissures ; the latter of 
which continue open upwards to the height only of a few feet, 
when they gradually close, and terminate in the body of the 
limestone: they are thickly lined with stalactite, and are 
attended by no fault or slip of either of their sides. Both the 
roof and floor, for many yards from the entrance, are composed 
of horizontal strata of limestone, uninterrupted by the slightest 
appearance of fissure, fracture, or stony rubbish of any kind ; 
but further in, the roof and sides become irregularly arched, 
presenting a very rugged and grotesque appearance, and being 
studded with pendent and roundish masses of chert and stalac- 
tite ; the bottom of the cavern is visible only near the entrance ; 
and its irregularities, though apparently not great, have been 
filled up throughout to a nearly level surface, by the introduc- 
tion of a bed of mud or sediment, the history of which, and also 
of the stalactite, I shall presently describe. (See Plate XIV. 
fig. 2.)
