Would like much to visit CD before returning to America;

is completing his work on evolution [Outlines of cosmic philosophy (1874)] for publication. Hopes to do away with the anthropomorphic distinction made between "divine action" and the "action of natural forces".

CD is glad to hear of nature of JF’s work;

proposes that JF call when CD comes to London.

Has read JF’s attack on Agassiz ["Agassiz and Darwinism"] in Popular Science Monthly [3 (1873): 692–705].
