[35] See Mr. G. W. Lamplugh’s opening address, delivered in Section C of the British Association (Nature, Aug. 16, 1906, pp. 387-400). Mr. T. F. Jamieson, in a valuable and interesting paper (Quart. Journ. Geol. Soc., lxii, 1906, p. 23), observes that ‘although we have some evidence of more than one recurrence of an ice-sheet in [Aberdeenshire] ... no evidence has hitherto been obtained of warm intervals, further than that which may be inferred from the melting away of the vast mass of ice which preceded and followed the deposition of the Red Clay and the shell-bed at Clava and elsewhere. It must have taken a great deal of heat to melt these enormous masses.’
[36] Is it certain that an elevation of seventy feet would not have been enough to unite Britain with the Continent? For thousands of years the scour of the tides must have been deepening the Channel. [On April 11, 1906, I submitted to Mr. Clement Reid, in a conversation which I had with him at the Geological Museum, the gist of the argument by which I endeavour to show (pp. 20-2, infra) that during some part of the Palaeolithic Age Britain must have been continental. He virtually admitted its force, remarking that an elevation of seventy feet would have enabled animals to cross from Gaul to Britain, as the scour of the tides had doubtless deepened the Channel.]
