Forwards a communication from A. Fonblanque for possible publication in Natural History Review. [See "Notice of mule breeding", Nat. Hist. Rev. n.s. 5 (1865): 147–8.]

Has received CD’s Copley Medal for him. Conveys regrets of Royal Society at his absence.

Discusses the affairs of the late Edward Evans for whom CD and EAD are trustees.

Has got CD’s [Copley] Medal, "it is rather ugly to look at, & too light to turn into candlesticks".

Acknowledges receipt of £262 13s. 5d.

Sorry to hear JH is still suffering from gout.

The [Royal Society] President’s address is in the Reader [4 (1864): 708–9], but one or two sentences have been omitted.

Recounts row at the Royal Society over exclusion of mention of Origin from Sabine’s address awarding Copley Medal to CD.

Encloses two letters to JDH from James Hector in New Zealand.

Sends photo for B. D. Walsh; requests those of New World entomologists, and CD’s.

His suspicions regarding [Edward] Sabine’s treatment of CD were justified by the Anniversary Address. THH, [George] Busk, and [Hugh] Falconer insisted on a more accurate account of the grounds on which the Copley Medal was awarded to CD.

Thanks GB for proposing him for Copley Medal; suspects he is responsible for the praise in Sabine’s "splendid eulogy" on his work. Has, however, written to Sabine to say he would have liked a little more said about the Origin.

Much pleased by Edward Sabine’s address.

Grateful to HF for his interest [in the award of Copley Medal to CD].

CD pleased with Huxley for defending him against Sabine. Also pleased with much of Sabine’s address. Is sure JDH wrote the botanical part.

Suggests James Hector observe which insects visit endemic New Zealand plants

and JDH examine distribution of white vs coloured corollas in New Zealand.

Thanks ES for his "splendid eulogium" [in Presidential Address to Royal Society on award of Copley Medal]. CD would have liked him to have said "a little more" about Origin.

CD feels no doubt about natural selection. Has heard from Germany of "a string of excellent men" who accept it.

Discusses Agassiz’s misrepresentations of his views and J. D. Dana’s "wild notions".

The reception is friendlier from younger scientists in France, and many of the best men in Germany.

Sends J. O. Westwood’s direction.

Congratulates CD on the Copley Medal.

Is making inquiries on the habits of American cuckoos and sends a letter from Henry Bryant on that subject.

Discusses the Civil War.

Encloses letter from W. H. Leggett containing observations on Amphicarpaea.

Sabine’s Royal Society address [awarding the Copley Medal to CD], in referring to the Origin, did not contain the words "expressly excluded". The actual words were "expressly omitted from the grounds of our award". This was not meant to place the Origin on a sort of index expurgatorium, but was a simple statement of fact.

Wishes to correct an expression in his last letter which is "perhaps not rigorously exact": he should not have said "declining to honour it [the Origin] with the Copley Medal" but simply "not honouring it with the Copley medal". "Declining implies having been asked and there was no asking in the present case."

Sabine’s address, printed in the Reader [4 (1864): 708–9], is good on the whole. Sends Huxley’s account of the row.

Praises John Ruskin’s eloquent reply to Jukes.

He is certain he heard "expressly excluded" [of Origin from consideration in Royal Society award of Copley Medal]. Believes GGS may have inadvertently substituted "excluded" for "omitted". THH then submits his reasons for objecting to the passage as a whole even with the word "omitted".

Congratulates CD on the Copley Medal.

Directs CD to his short memoir on crossing ["De l’hybridité", C. R. Hebd. Acad. Sci. 59 (1864): 837–45].
