Bones discovered in a cave at Kirkdale, in Yorkshire. 227 
burial ; they were about 30 feet below the present upper sur- 
face of the lime-stone rock. 
3. The other case occurred, in 1810, at Llandebie, in Caer- 
marthenshire, where a square cave was suddenly broken into, 
in working a quarry of solid mountain lime-stone on the 
north border of the great coal basin. In this cave lay about 
a dozen human skeletons in two rows at right angles to each 
other. The passage leading to this cave had been entirely 
closed up with stones for the purpose of concealment, and 
its mouth was completely grown over with grass. 
It is obvious, that in neither of these cases, are the bones 
referable to so high an era as those of the wild beasts that 
occur in the caves at Kirkdale, and elsewhere. 
P. S. As this paper was going to the press, I have been 
gratified to hear that my conjecture, as to the abundance of 
such caverns as that at Kirkdale, has been verified by the dis- 
covery of another cave (containing chambers lined with sta- 
lactite, and having on its bottom mud, and bones imbedded 
in the mud), in a quarry close to the town of Kirby Moor- 
side, on the property of C. Duncombe, Esq., who has judici- 
ously taken every precaution to secure it from injury, till 
some qualified person shall be present to observe, and record 
the undisturbed appearance presented by its interior. Should 
it be in my power, as I hope it may, to assist at its farther 
opening, I shall communicate the result to the Royal Society. 
It is recollected also, that about 20 years ago, another 
cavity, containing bones, was discovered on the north of Kirby 
Moorside, but none of them have been preserved. 
Though it is probable, as I have stated, that such caverns 
are not uncommon, we shall cease to wonder that they are
