The cave, ever since I knew it, has been completely closed 
up by a large mass of rock several tons weight ; but around 
the entrance, the soil still abounds in fragments of bones, 
shells, wood-ashes, &c. 
Fortunately Mr Beattie preserved, in the Montrose Mu- 
seum, a considerable quantity of the debris at the time the 
cave was open, and a study of this, as well as of the frag- 
ments since picked up by myself, will, I think, bear me out 
in my interpretation of its history. It will be observed that 
Mr Bryson and Mr Beattie both, unintentionally as it were, 
give evidence in favour of the human theory, and against 
their own. Mr Bryson refers to the arrangement, or " strati- 
fication" as he calls it, of the different kinds of materials; 
to the bone of an ox, which " bore evident traces of being 
saAvn or ground flat," and to an amulet formed rudely of 
the leg bone of an ox." Mr Beattie again states, that " this 
extraordinary deposit of shells contained no admixture of 
sand or earthy matter, but lay pure and clean as if heaped 
together by human agency. The following list comprehends 
most of the animal remains preserved, viz. : — Shells of 
Mytilus edulis, Cardium edule, Litorina littorea, Buccinum 
undatum^ Fusus antiquus, Patella vulgata, Helix nemoralis ; 
fragments of the claws of Cancer pagurus; leg bones and 
bills of Sula hassana ; bones of Cervus elephus, Cervus 
capreolus^ Sus , Erinaceus europeus, Bos , Felis 
catus, Canis familiar is, Canis vulpes, Hypud(jeus , M^is (?) 
; and a portion of a human parietal bone and radius. 
The shells of the mollusca are all of large individuals, 
particularly those of Patella vulgata. At the present time 
the beach nearest the cave is either shingly or flat and 
sandy, and it is not till you go several miles north or south 
that you come to the habitat of the marine species above 
mentioned. The same remark applies to the edible crab, 
which does not live within two miles of the cave. * 
The frequency of the bones of the solan goose is remarkable. 
This bird only visits these shores in summer, when it is often
