y(J T. BELT OX THE DRIFT OP DEVOX AXD COEXWALL. 



glaciation might be observed running in every direction ; and it was 

 not fair to note only certain striae, and neglect those which were 

 not in favour of a foregone conclusion. He thought that Mr. Camp- 

 bell had shown clearly that the glaciation of Ireland took place from 

 the north-east. 



Mr. Moggeidge remarked that a very flat country extended across 

 the continent of Europe from England to the Black Sea, and thought 

 that in that direction there was no land sufficiently high to form the 

 boundary of such a lake as that required by the author's theory. 



Rev. T. G. Boxxey said that, in addition to the difficulties which 

 Prof. Hughes had mentioned, four others at least occurred to him : — 

 that the barrier to Mr. Belt's lake was defective between the high- 

 lands of Brittany and the Auvergne ; that the ice in its course from 

 Greenland would have to cross a part of the Atlantic where the 

 depth approached 2000 fathoms, which seemed to demand an incon- 

 ceivable accumulation in that country; that under such circum- 

 stances Wales, Scotland, and Scandinavia must have had their own 

 ice-systems ; and that to reach Scandinavia (which certainly had its 

 own ice-system), this great sheet must have crossed the Lofoten 

 Islands, yet all the higher hills in these were remarkably sharp and 

 broken. Further, in regard to what Mr. Belt had said about the 

 lowering of the general level of the sea, it must be remembered that 

 such an ice-cap would raise the level in the hemisphere where it 

 occurred. 



Mr. Belt, in reply, said that he did not want the ice to stop at 

 Cornwall, but that his statement as to its limits was founded on 

 observed marks of glaciation. He thought the absence of marine 

 remains throughout the drifts of the northern plains of Europe was 

 a highly important and suggestive fact. With regard to the glacia- 

 tion of Ireland, he remarked that the ice flowing south-east from 

 Greenland would strike against the high lands of Scotland and 

 England, and be turned back over Ireland. The lowering of the 

 sea was not absolutely required by the necessities of the paper ; 

 but if the accumulation of ice took place simultaneously at both 

 poles, the sea must necessarily be greatly lowered.
