PKOr. J. PEESTWICH ON THE EAISED 



(16) Tenhy and Caldy Island.— 1 may here refer also to the 

 ossiferous fissures at these two localities, which, like those of 

 Oreston, have been spoken of as Caverns. Those on Caldy Island 

 are now quarried away, but it is evident, from Mr. G. N. Smith's 

 description of them, that they were fissures with vertical walls 

 containing ossiferous breccia, though it is by no means certain 

 whether there was not also a true cave, as gnawed bones are said to 

 have been found on the island. The bones were so numerous that, 

 besides a number thai were shovelled into the sea, three sackfuls 

 were shipped away to be used as manure. The bones that I saw 

 in the Tenby Museum were in a singularly good state of preserva- 

 tion, being almost as fresh-looking and heavy as recent bones, and 

 having lost so little animal matter that they did not adhere in the 

 least to the tongue. The animals recorded there are Felis leo, 

 Canis lupus^ G. vulpes, Hycena sjpelcea, Ursus Sjpelceus, Elephas pri- 

 migenius, Rhinoceros megarhinus, Equus cahallus, Bos, and Cervus. 



At Black Eock, near Tenby, I found an inclined fissure (a) in 

 the Carboniferous Limestone, full of limestone-debris and earth 

 with bones of Mammoth, Ehinoceros, &c., and was told that an 

 almost entire skeleton of Ehinoceros had been found in it. In the 

 same quarry there was to be seen a nearly circular vertical pipe (p), 

 filled with red soil, and apparently 50 to 60 feet deep, but without 

 any animal remains.

I take the pipe to be of older date than the fissure, which is 

 coeval with the fissures on Caldy Island. 



(17) Dorset. — The slopes of the hills and lower parts of the 

 valleys are in Dorset, as in Devon, often covered by a drift to a 

 considerable depth ; but here again, and in Somerset, the Valley 

 Gravels have not been worked out in sufficient detail to separate the 

 drifts of different ages. I feel uncertain whether the Mammoth 

 remains found near Charmouth belong to the later drift or to the 

 Valley Drift. The Eubble-drift at Encombe I have already noticed. 



(18) Hampshire. — In the neighbourhood of Southampton we find 

 traces of the Eubble-drift on the slopes of the surrounding hills, as, 

 for instance, Eed Hill and Otterburn Hill, but there are no well- 

 marked sections. Possibly some of the high-drift gravel with flint 

 implements on Southampton Common should be placed in this 

 group. I think it also probable that the patch of drift at Down- 

 ton ^ (in which I found a sharp-pointed flint implement) should be
