Pleased ACR likes Origin. Every geological believer is most important. A long, stiff battle is ahead for the new doctrine.

Would like to hear ACR’s new views on origin of mountain lakes, but cannot stand the hot, late meetings [at Geological Society].

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.

Thanks ACR for Catalogue; pleased some of his volcanic specimens have been included.

Will review T. F. Jamieson’s paper on Glen Roy. Knows the facts and knows too well that he [CD] is everlastingly smashed.

Interested in ACR’s Presidential Address [Q. J. Geol. Soc. Lond. 19 (1863): xxix–lii] on the breaks in succession (of formations). Hopes ACR will provide a diagram of breaks, with the percentage of fossils that "pass upwards", i.e., continue to appear.

Horrified at Huxley’s geology.

Wishes ACR would discuss "creeps".

Thanks for his book [Physical geology and geography of Great Britain, 2d. ed. (1864)].

Pleased that ACR’s glacial lake theory is progressing. New Zealand lakes support the view. Suggests he write to Charles Gould in Tasmania, calling his attention to glacial action.

Thanks for Geological survey of North Wales [1866]. Longs to return to the mountains with which he was once familiar, but did not understand.

Received and read ACR’s Physical geology. Places him at head of the subaeria denudationists. Unfortunately CD confounded William Whitaker’s article with ACR’s views and gave Whitaker credit for first producing the evidence. Will rectify it now. Has eliminated the rubbish he wrote on the Weald and will add a paragraph on importance of subaerial denudation.
