Studying glacial drift in NW. England, he finds evidence of intense glacial activity, but the molluscan fauna does not appear to indicate a low sea temperature. Requests information on Tierra del Fuego molluscs for comparison.

Sends his paper ["Tidal action as a geological cause", Proc. Liverpool Geol. Soc. 2 (1874): 50–72].

Has not yet studied CD’s list of South American molluscs.

TMR’s address ["Geological time" (Presidential Address, 1876), Proc. Liverpool Geol. Soc. 3 (1878): 211–35] not yet published. Will send copy.

TMR believes rate of limestone formation is same now as in past.

He expects his address [of 10 Oct 1876] on geological time [Proc. Liverpool Geol. Soc. 3 (1878): 211–35], which contradicts William Thomson’s view of the earth’s age, to appear soon.

Sends his paper ["Oceans and continents", Geol. Mag. 7 (1880): 385–91].

Thinks John Murray of Edinburgh goes out of his way to deny an elevation/subsidence view of coral reefs ["On the structure and origin of coral reefs and islands", Proc. R. Soc. Edinburgh 10 (1878–80): 505–18].

Recommends letters by William Topley in Geological Magazine. WT discusses past distribution of oceans and continents.

Argues against volcanic origin of coral islands and for the submergence of continents. Cites Judd’s argument on the volcanoes of the moon.

Praise for Earthworms.
