Thanks ACR for papers.
Glad present situation of our continents has been confirmed.
Wishes ACR would prove his view of origin of Red Sandstones, which many dispute.
Requests further information on subsidence of flagstones because of action of worms.
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.
Glad CD agrees with his views as much as he does. Not surprised that his red rocks [Red Sandstones] ideas are disputed. The red marls of Auvergne support his inland water theory.
Sends description and measurements of the 18th century courtyard pavement of his house, the stones of which have sunk as a result of earthworm action [see Earthworms, pp. 192–3].
Further details and measurements of the stones in the courtyard pavement for CD’s investigation of earthworm action.
