Has finished the last proof of his monograph [Fossil Lepadidae] and returns WH’s specimens. Has named two new species from the collection.

Will return all but two volumes; requests four titles, including Pepys’s Diaries, but not the first volume.

Thanks PHG for information about the bald-pate pigeon.

Will write to Richard Hill.

Can PHG remember any facts relevant to transport of animals and plants to distant islands?

Reports long preparation of work on how species and varieties differ. Agreement with Wallace’s conclusions as reported in Annals and Magazine of Natural History and in his letter to CD of 10 0ct [1856]. On distinction between domestic varieties and those in "a state of nature".

On mating of jaguars and leopards, the breeding of poultry, pigeons, etc.

Requests help for his experimenting on means of distribution of organic beings on oceanic islands.

Comments on agreement of their respective views on distribution.

Reference to differences on subsidence.

Reports on progress of his work and praises ARW’s investigations.

Expresses pleasure and relief at ARW’s response to joint publication of their pieces about natural selection.

Plans for the "abstract" [Origin].

Birds’ nests as evidence of variation of instincts.

Their collection of bees’ combs.

Praises ARW’s article.

Lyell’s and Hooker’s views [of species issue].

First part of Origin MS is with Murray;

CD hopes he has noticed ARW’s work fairly.

ARW is right in thinking that CD was led to believe that selection was the principle of change from studying domesticated productions and that after reading Malthus he "saw at once how to apply this principle". Geographical distribution and geological relations of extinct and recent inhabitants of S. America first led him to the subject, "Especially case of Galapagos Islds". Hooker and Lubbock are full converts and Huxley now believes in species mutation. "We shall live to see all the younger men converts."

Praises ARW’s work and spirit.

CD had actually written a letter to ARW stating he would not publish before him but was persuaded by Lyell and Hooker to allow them to act "as they thought fair & honourably".

Will forward ARW’s "admirable" paper to Linnean Society ["On the zoological geography of the Malay Archipelago", J. Linn. Soc. Lond. (Zool.) 4 (1860): 172–84].

Discusses geographical distribution of animals in the Malay Archipelago; relation of distribution to depth of sea between islands.

Relation of Celebes to Africa almost passes belief.

Differs wholly from ARW on colonisation of oceanic islands; does not believe in Forbes’s great continental extensions.

Anticipates Owen’s opposition to their views, but "he is a poor reasoner & deeply considers the good opinion of the world, especially the aristocratic world".

A copy of CD’s book [Origin] has been sent to ARW; invites his comments. "God knows what the public will think". Hooker believes Lyell is a convert, but CD does not think so, although he is "deeply interested". If he can convert Huxley, CD will be content.

CD expected AS’s "strong disapprobation" of his book [Origin] but is grieved "to have shocked a man whom I sincerely honour". Has worked "like a slave" on the subject for over 20 years and is not conscious that bad motives have influenced the conclusions at which he has arrived. CD does not think the book will be mischievous and "if I be wrong I shall soon be annihilated". CD may have written too confidently from feeling confident that no "false theory would explain so many classes of facts".

Returns MS [of biography for Dictionary of contemporary biography (1861)]. Part was inaccurate, and there was an important omission so CD has had a new copy made.

Declines the honour of acting as Steward at the Annual Dinner of the Royal Literary Fund.

Much obliged for note from Alexander von Keyserling. Geologist going one inch with CD more important than naturalist going two or three.

Pleasure in ARW’s approbation of the Origin. Other supporters among scientists. ARW’s generosity.

Attacks by Owen, Sedgwick, and others.

Anticipation of natural selection by Matthew in 1830.

CD is not surprised at CC’s entire rejection of his views. Agrees that there is no direct proof of unlimited variation. Says natural selection should be viewed as comparable to wave theory of light: it is probable because it groups and explains a host of facts in several fields of science.

Agrees Louis Agassiz’s review [Am. J. Sci. 2d ser. 30 (1860): 142–55] is not unfair, but Agassiz misunderstands CD. His "categories of thought" are to CD merely empty words.

Gives directions to Down. Would be happy to see SPW but regrets they "have no attractions".

Agrees about colonisation of Arctic region.

CD thought that his St Helena land shells had quite recently become embedded; his specimens are at the Geological Society.

Can SPW ask A. Günther for any references to Silurus escaping from the Danube?

Declines the honour of acting as Steward at the Annual Dinner of the Royal Literary Fund.

Quarterly Review piece written by Bishop Wilberforce with aid of Owen.

Other reviews mentioned.

Health.

Family illnesses.

On disposition of wild honeycomb gift.

Discounts the difficulty presented by ostrich wings.

Baffling problems with Melastoma. Appreciates ARW’s help with it and the "gorze case".

Has read report of ARW’s paper [to Newcastle BAAS meeting, "On the geographical distribution of animal life"] in the Reader [2 (1863): 352–3].
