CD’s sons tell him that Samuel Butler in Unconscious memory states that some passages in Erasmus Darwin were taken from his Evolution, old and new. Their unprejudiced view is that the passages do come from Butler. CD hopes EK will give a clear explanation if he writes on the matter in Kosmos.

CD is taking no public notice of Butler’s attack on himself.

CD is pleased with EK’s account in Kosmos [8 (1880–1): 321–2] of the Buffon and Coleridge passage [cited by Samuel Butler, see 12939, 12969]. Would like a translation published in England, but Butler seeks notoriety and would make unscrupulous use of it. Will ask advice. Thinks EK’s letter to Popular Science Monthly, just received, an excellent reply to Butler.

All his advisers agree that CD ought not to take notice of Butler’s attack.

F. M. Balfour has offered to translate EK’s reply to Butler and to send it to Nature. [The letter was published in Nature 23 (1881): 288.]

Sends copy of Nature in which EK’s letter, translated by Balfour, is printed. Thanks him. Now feels easy.

G. J. Romanes’ language in his review of Butler’s book [Unconscious memory] is perhaps too strong. Butler’s vanity is a "real psychological curiosity".

Butler’s reply to EK is a renewed attack on CD. Urges EK not to answer it. His last letter contains everything necessary. Asks EK for dates of CD’s letter asking EK’s permission to publish a translation of his article [on Erasmus Darwin] and of the letter in which he told EK that Butler’s book had been advertised.

Thanks EK for his article [on CD’s Movement in plants].

Admires EK’s wide interest in science. Would like to send him something to publish in Kosmos.

Fears his new book [Earthworms] will hardly do, but will send sheets when printed so that EK can decide whether any chapter or a part of one will serve. Victor Carus’s consent would be needed for publication in Kosmos, and CD will ask for it.

Publication of Earthworms delayed, but will send sheets to EK when he receives them [so that he can decide about publishing extracts in Kosmos].

Thanks for "Die Gegenwart".

"’Instinct’ of plants" is a most puzzling problem.

Does not see how mind can be defined "if we subtract consciousness".

As editor of the new journal, Kosmos, thanks CD for the permission he has granted Ernst Haeckel to publish with CD’s approval.

Cites his long support for evolution as exemplified by his book [Die botanische Systematik in ihrem Verhältniss zur Morphologie (1866)].

CD has many German supporters.

Asks permission to print translation of "A biographical sketch of an infant" [Collected papers 2: 191–200] in Kosmos.

Notes divisions among German Darwinists.

Thanks CD for permission to print ["Sketch of an infant"] in Kosmos.

Discusses children’s ability to distinguish colours.

Describes disagreements among German supporters of CD. Discusses reaction of German protestants to Darwinism.

Birthday greetings.

Glad CD is pleased by his "Erasmus Darwin". Was not able to obtain book by Anna Seward [Memoirs of the life of Dr Darwin (1804)]. Could CD check relevant passages for errors? Would be great honour if CD could arrange English translation. Wants to enlarge essay into book.

Had doubts about excerpt from Anna Seward’s book [Life of Dr Darwin]. Sends slightly enlarged version of his "Erasmus Darwin". Includes footnote denouncing Seward’s book.

Finds that part 2 of ED’s Botanic garden, 2d ed. (1790), appeared before part 1 (1791).

Thanks for sketch of Erasmus Darwin by John Dowson [see Erasmus Darwin, p. iv]; would like to incorporate this information into MS. Previous biographers of Erasmus Darwin had insufficient knowledge of what appeared in his works.

Wants to finish revision of MS on Erasmus Darwin before Dallas begins translation. Has discussed possible German edition with Carl Alberts.

Sends first part of MS of Erasmus Darwin.

Has found useful criticism of Anna Seward in J. G. Lockhart’s Life of Sir Walter Scott.

CD should regard MS as a draft and correct anything that seems incorrect or questionable. Asks biographical questions about Dr Darwin. Can CD give information about origin of family name?

Will wait for CD’s preliminary essay before proceeding with German edition [of Erasmus Darwin]. Regards CD’s essay as the principal attraction. Would like to finish German edition by end of July.

Thanks for answers to questions [in 12032].

Has ordered the new book by Butler [Evolution, old and new (1879)]. It may make EK’s own essay superfluous.

Samuel Butler seems not even to have read works of Erasmus Darwin. Quotes only passages quoted by other authors. Thorough account now more necessary than ever.

CD’s preliminary notice should be incorporated in German edition completely unchanged, though some annotation is needed to explain matters unfamiliar to German readers.

Would like to have article by CD for Kosmos.

Hopes to send last part of his work soon. CD may lay it aside or print only parts of it. Wants to add account of evolutionists before Erasmus Darwin. Superficial account by Samuel Butler makes this necessary.
