Mr W. E. Hoyle on Loligo Forbesii, Steenstrup. 459 



In conclusion, I think the suggestion may be hazarded 

 that this 20 feet of sand and gravel, full from bottom to top 

 of West Highland blocks, which Mr Craig clearly states lies 

 between the carboniferous strata and the mammoth beds, 

 shows that the statement in the explanation to sheet 22 

 requires not correction but expansion — and that if in addition 

 to the warm interglacial season it predicates to account for 

 the retirement of ice from the land to permit an arctic 

 vegetation to grow on it, and some of the larger northern 

 mammals to roam over it, we must also suppose a partial 

 submergence, during which the lower boulder-clay in certain 

 places was by water reasserted into sand, gravel, and mud, 

 and redeposited with its boulders water- worn, as the laminated 

 beds so graphically described by Mr Craig.

Some details respecting the action of the suckers in
