Asks ACR to establish height of Moel Tryfan in Caernarvonshire; "in my notice on this hill [""Ancient glaciers of Caernarvonshire"" (1842), Collected papers 1: 163–71] I give a very much less height than others".

Summary:

ACR has for years had a belief in mutability and transmutation of species, prompted by disputes over the nature of species and varieties, and the existence of representative species in space and in the geological record. Could not accept a Creator employing small miracles to make species differ just a little between formations. Has maintained that one would not expect to find fine gradations between forms in the fossil record, but only representatives of very populous forms. [See 2711.]

Summary:

On ACR’s paper on glacial origin of lakes. CD thinks it is correct. Suggests further investigation to corroborate it. His only doubt has to do with areas of great activity.

On ACR’s view of cause of glacial period: CD did battle with Hooker on same point.

T. F. Jamieson has smashed CD’s Glen Roy marine theory in splendid style.
