364 THE PI.EISTOCENE DEPOSITS OP THE SUSSEX COAST. 



evening ; but he thought that it would probably bear fruit in many 

 papers which would hereafter be written, dealing with the several 

 points, by those acquainted with the special districts and sections 

 referred to. With regard to the views of Mr. Clement Reid, he cri- 

 ticized the evidence offered of a mild age between two cold ages, and 

 said that he had much difficulty in understanding how, during a 

 period of such severe glaciation as to allow of the transport of 

 boulders in ice from Britanny to Sussex, there should not have been 

 northern ice pushing its way south ; unless we supposed a great 

 elevation in Britanny, and a great depression in the English 

 Channel. He drew attention to the manner in which single 

 boulders were carried along a shore, and the mode of settlement 

 of stones into non-calcareous strata, and asked whether the boulders 

 noticed by Mr. Eeid might not have been merely fragments of local 

 rocks, with here and there a boulder, the relic of patches of drift 

 now all washed away ; and whether they might not all have been 

 trundled along by the sea to the place where he found them, and 

 have been half buried by one or other of the processes which he had 

 just described. 



Dr. Hicks said he did not think the evidence was quite con- 

 clusive that the erratics of non-local origin referred to by Mr. Eeid 

 had not been brought from a northern source, either by ice floating 

 down the Channel, or passing across some part of England. 



Prof. Seelet, Mr. Whitae:ee, and the Eev. H. H. Winwood also 

 spoke. 



Mr. C. Eeid replied to the observations made on his paper.
