Lyell says CD is revising what he says about the Weald in the Origin. Asks CD to look at his subaerial denudation views in his book [Physical geology and geography of Great Britain, 2d ed. (1864)].
Sends two papers ["On the physical relations of the new red marl", Q. J. Geol. Soc. Lond. 27 (1871): 189–98 and "On the red rocks of England", Q. J. Geol. Soc. Lond. 27 (1871): 241–54] bearing on the continuance of generic and specific terrestrial types, in areas of Europe and elsewhere, that lasted from the Upper Silurian to the Lias.

Further details and measurements of the stones in the courtyard pavement for CD’s investigation of earthworm action.
