DRlFrS OF FLAMBOROUGH HEAD. 431 



which Mr. lleid had raised, as they had on these points always held 

 different views, lie believed that this was chietly because Mr. Keid 

 had worked northwards from the Humbcr, while the Author had 

 worked southwards from Flamborouj^li. 



On ilamborough Head the Intermediate beds could not be 

 marine, but the sea may possibly have been present in some part of 

 the Holderness recess during their deposition, though the evidence 

 for this was by no means convincing, and part, at any rate, of the 

 fauna could scarcely be contemporaneous. If the Holderness 

 "inter-Glacial" deposits were older than the Basement Clay, as 

 Mr. Reid supposed, it was curious that they should have retained 

 their mound-like features during the extended glaciation which 

 followed. 



He thought it was unsafe to rest any conclusions on the dip of 

 the deposits in this area, as they were evidently moulded upon a 

 pre-Glacial surface, and were, besides, in every way irregular. 



The mounds had much in common with eskers, but their direc- 

 tion and their position near the edge of the glaciated area could not 

 be explained on the commonly-accepted esker-theory. It was 

 difficult to say how to define the term " esker," and when to 

 apply it. 



He admitted the glacial character of the mammalian fauna of the 

 Buried-Cliff beds, but thought that this was what we might expect 

 to find below the Boulder-clays in an area so far removed from the 

 centres of glaciation. 



The Buried Clifi' had been preserved from subaerial degradation by 

 the blown sand which was banked against it.
