54 GLACIAL ACTION IN S. BRECKNOCKSHIRE AND E. GLAMORGANSHIRE. 



Discussion. 



The Chairman (Dr. J. Gwyn Jeffreys) said that the district was 

 well known to him, and that he had examined parts of Glamorgan- 

 shire with reference to the present question, and he believed that 

 there was evidence there of land-glaciation only, the remains of 

 moraines being occasionally discernible — differing in this respect 

 from the northern comities of Wales and England, which give unmis- 

 takable indications of marine action, and sometimes at a present 

 height of over 1300 feet. In the southern counties of England there 

 was a similar absence of so-called glacial shells, and no evidence of 

 elevation. He invited discussion on this interesting communication. 



Prof. Prestwich expressed his regret at the absence of the author, 

 and his sense of the value of the paper. It formed an excellent sup- 

 plement to Mr. Mellard Reade's important paper, to which the Society 

 had already listened. The south of Wales had hitherto received but 

 little notice as compared with North Wales. One distinction to be 

 noticed in this district was that the erratics were local, while in 

 North Wales erratics were present from districts far to the north. 

 It was singular that south of the Bristol Channel the indications of 

 ice-action should be so obscure and uncertain, when they were so 

 clear to the north of it.
