CD is leaving home for three weeks’ rest. If EK finishes his life of Dr Darwin while CD is away, asks him to send the MS to W. S. Dallas for translation. CD will begin his preface, but needs rest and will not do much until he returns.

Thinks it better to send proofs of his preface [to Erasmus Darwin] rather than MS – he always corrects proofs heavily. Doubts that it is worth translating into German – it is written for the English public. Supposes EK will not object to a French translation and an American edition of the little book. Has written a dozen pages during a break

in his experimental work [on movement of plants].

Answers EK’s queries about Erasmus Darwin’s friends and relations. Will rectify Anna Seward’s false account of Dr Darwin’s conduct. Advises EK to leave to him the account of the Darwin family. Declines EK’s offer to allow CD to alter his MS. Fears repetition in the two essays. They can judge how best to present the material when they have seen each other’s manuscripts.

Assures EK he will lose no time in writing his essay [on Erasmus Darwin].

A book by Samuel Butler on Erasmus Darwin and Lamarck has been announced [Evolution, old and new (1879)]. Will have a copy sent to EK.

Assures EK that he will not change his mind about publishing a translation of EK’s article on Erasmus Darwin. It is unfortunate that Samuel Butler should have published [Evolution, old and new] just then, but that does not change CD’s determination.

Butler is clever, but knows no science. His views that cells have memory and the power of wishing – even if correct – cannot explain how they could change themselves chemically or structurally.

EK can do anything he likes with CD’s preface [to Erasmus Darwin].

CD’s preface [for Erasmus Darwin] is delayed by his sitting for a portrait.

Explains to EK why he feels unable to contribute articles to Kosmos.
