 the rocks about Ventnor Cove, and in various parts of the 

 undercliff, Mr. Webster remarked, in the sandstone stratum 

 immediately under the chalk marl, a great number of small 

 prominences, resembling in form the branches of trees. 

 They were of various sizes, from half an inch to three or 

 four inches in diameter; their substance was sandstone, of 

 the same kind as the rock they were in ; but the part resem- 

 bling the bark was somewhat harder, which enabled it to 

 endure longer than the rest of the stone, and thus project 

 above its surface. Some of them were straight, others a lit- 

 tle crooked, and in a few instances he observed them forked. * 

 He found fragments of these bodies in. every part of the 

 island, where the sandstone stratum can be seen, and parti- 

 cularly among the masses of rock lying under the cliffs of 

 Western Lines. In this last place he found, that the stems
