The caves have contributed but very little to our knowledge of the bronze-folk in any part of Europe. Examples, such as those given above, are scattered through France and Spain, but they are not sufficiently important to require notice. We could not expect that men, in the high state of civilization implied by the beautiful jewellery and ornaments which are distinctive of the bronze-folk, would have chosen the wild, half-savage life which is involved in cave-habitation.

It is evident, from the scanty remains found in caves, that they were not the normal habitations of men in the Bronze or Iron stages of culture. We shall, however, find that they were used by the neolithic peoples, both for shelter and for burial, in nearly every portion of Europe which has been explored. _Neolithic Caves in Great Britain.--Perthi-Chwareu._ The most remarkable examples of caves, turned to both these uses, in Britain, are offered by the group clustering round a refuse-heap at Perthi-Chwareu, a farm high up in the Welsh hills, about ten miles to the east of Corwen, and a mile to the west of the little village of Llandegla, in Denbighshire. _The Refuse-heap._ The first intimation of any prehistoric remains in that locality was afforded by a small box of bones forwarded to me by Mr. Darwin, in 1869; and this I was able to follow up, through the kind assistance of Mrs. Lloyd, the owner of the property on which they were found, from time to time, during 1869-70-71-2. The mountain limestone, which there forms hill and valley, consists of thick masses of hard rock, separated by soft beds of shale, and contains large quantities of _producti_, crinoids and corals. The strata dip to the south, at an angle of about 1 in 25, and form two parallel ridges, with abrupt faces to the north, and separated from each other by a narrow valley, passing east and west along the strike. The remains sent by Mr. Darwin were obtained from a space between two strata near the top of the northern ridge, whence the intervening softer material had been carried away by water. Its maximum height was 6 inches, and its width 20 feet or more; and it extended in a direction parallel to the bed of the rocks. The bones, which had evidently been washed in by the rain, and not carried in by any carnivora, belong to the following species:--
