Prof. Buckland On the Caves at Kirby Moor side, 
has been laid bare by the workings of the quarry, and on the 
face of it there are traces of a fissure connected with several 
small cavernous holes. The aperture discovered last spring is in 
the centre of this quarry, and near its floor. On removing the 
wall with which Mr Duncombe had caused it to be closed, it was 
found to pass obliquely into the body of the hill, and to be inter- 
sected at a few feet from its entrance by a large fissure. This 
point of intersection forms, as at Kirkdale, the widest and most 
lofty part of the cavern, within which it diminishes into smaller 
vaults, which soon become impassable : the outer part of the 
cave when first opened was about four feet high and six broad, 
and its entire floor covered with an uniform mass of loamy clay, 
precisely similar to that on the floor of the den at Kirkdale. 
On digging into this loam it was found to be six feet deep for 
a considerable distance inwards, and to contain no bones. At 
its bottom there was no stalagmitic under-crust dividing it from 
the limestone floor, nor any repetition or alternation of a se-^ 
cond or third bed of stalagmite in any part of its substance. 
Its surface alone was in many parts glazed over with an ex- 
tensive sheet of it oozing outwards from the side walls, and 
sometimes entirely crossing and forming a bridge over the loam. 
Above this crust some parts of the roof and sides were loaded 
with stalactite in its usual fantastic forms ; but there were no 
bones of modern animals, nor traces of loam, or even of dust, 
upon the surface of the superficial crust of stalagmite. In all 
its circumstances, as far as they went, it agreed with, and con- 
firmed the history and chronology I have given of the cave at 
Kirkdale, excepting the two accidents of its not having been in- 
habited as a den, or received any stalagmite on its floor, before 
the introduction of the diluvial loam. The absence of bones in 
this cave (the mud being present) adds to the probability that 
it was by the instrumentality of the hyaenas, and not of the di- 
luvial waters, that the animal remains were collected in such 
quantities in the adjacent den at Kirkdale. 
66 At about a mile east of Kirby Moorside, at a spot called the 
Back of the Parks, there are other quarries on both sides of a 
comb that descends rapidly into the valley of the Dove, in the 
face of which there occur several small caverns and vertical 
fissures : these fissures vary from one to six feet in breadth, and
