Discusses views of Wallace, H. N. Moseley, and Croll on the mechanics of glacier movement.

Comments on Wallace’s new book [The Malay Archipelago (1869)].

Asks for a photograph of CL to be used by a society [in Serbia].

Comments on article by Wallace ["Sir Charles Lyell on geological climates and the Origin", Q. Rev. 126 (1869): 359–94].

and is back at work on sexual selection [Descent].

Cites article by David Forbes dealing with the geology of the S. American Cordillera ["Geology of Bolivia and South Peru", Q. J. Geol. Soc. Lond. 17 (1861): 7–62].

Discusses the flexures of the Cordillera, the age of the mountains, and basaltic dikes in granite areas.

Leonard Jenyns cannot go as far as CD, yet cannot give good reason.
