Note 35 — Chapter II

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.’
