Response to 6th ed. of Origin. CD’s answer to Mivart on initial stages of modifications is complete; the "eye and ear objection" is not handled so satisfactorily.
Thanks for new [6th] edition of Origin.
Is working on Echini.
The more material he gets the less easy it is to diagnose a genus or species. Has little doubt that "classification is nothing but the most arbitrary convenient tool, depending upon the material at our command at a special time".
A. S. Packard would like to visit CD to pay his respects.
JM arranges to pay CD for the latest issue of Descent.
Wishes to use some of Fritz Müller’s observations in his paper on mimicry.
CD’s reply and Huxley’s article ["Mr Darwin’s critics", Contemp. Rev. 18 (1871): 443–76] have answered all of Mivart’s objections to natural selection as applied to man.
Has just finished his work [? The martyrdom of man (1872)]. The new points are: (1) Negroes have whiskers; (2) their music is sometimes agreeable; (3) the Kaffirs are Negroes.
Plans for visit to CD.
On how various human emigrations have supported the work of natural selection.
Defends the view that soil and air account for taller stature of westerners in U. S.
CD insists too strongly, in Descent, on man’s origin from a simian ancestor, rather than some other primate.

Endorses revised statement about Butler’s odd hereditary habit;
describes a séance at William Crookes’s.
Sends two vines for CD’s experiments, with instructions for grafting.
Mentions a hybrid plum–peach.
