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".

Sorry to hear of AS’s poor health.

Would like to attend Aberdeen meeting [BAAS, 1859] but is unfit for so great an exertion. Has been told he has "suppressed gout".

Pleased that AS remembers their 1831 geological trip, which made CD appreciate the noble science of geology.

Writes of a visit to Leith Hill and WED’s injured ankle.

Sheets [of Origin] up to p. 240 are ready. Asks how many copies and how soon JM will publish. Hopes as soon as possible because of his health. Bitterly disappointed at delay he has caused.

All but last two chapters of Origin proofs corrected.

Praise for JDH’s introductory essay [to Flora Tasmaniae].

Very ill and sick of work.

CL’s research on flint tools.

Promises to send proof-sheets of Origin. Discusses his view of species.

Ill health of himself and his family.

Delighted with JM’s suggestions. Asks JM to send sheets to Lyell.

On title of Origin, suggests omitting word "Varieties" altogether if JM does not object. Last proofs corrected, but revises still to do.

Inquires about the chances of meeting her when he goes to Ilkley for a cure.

Corrected last proof of Origin yesterday. Still has revises and index to do.

Will read more JDH proofs of Flora Tasmaniae.

Reports the results of some poultry crossing experiments; comments on transmission of different features.

"My unlucky Book [Origin] will be published 1st week in November."

Thanks CL for his favourable remarks to the Geological Section of the BAAS concerning the forthcoming publication of the Origin. Hopes CL will accept his view of species.

Comments on CL’s paper ["On the occurrence of works of human art in post-Pliocene deposits", Rep. BAAS 29 (1859): 93–5].

His book [Origin] is nearly done. Is not so silly as to expect to convert WDF. Lyell is wavering; Hooker has come round.

Family news.

Asks WDF to find out if a cross between differently coloured horses produces a dun.

Discusses text of Origin.

Compares Eocene and modern climates.

Mentions Hooker’s view of his geographical [distribution] chapters.

Asks CL’s opinion of his statements on distribution during "glacial and preceding warmer periods".

Mentions chapters on geological record and embryology.

Encloses draft in payment for tutoring of sons Francis and Leonard, with thanks for all GVR’s assistance.

Will send his servant for Arum plant.

Is sending off last proof-sheets of Origin.

Asks CL’s opinion of final chapter. Mentions difficulties of his argument.

Is too unwell to start for Ilkley.

Murray’s printing of 1250 copies seems too large to CD.

First impressions of the water-cure establishment are not favourable – "I always hate everything new".

CL’s comments on Origin. Mentions corrections to last chapter suggested by CL.

Comments on lack of peculiar bird species on Madeira and Bermuda. Emphasises importance of American types in Galapagos.

Denies necessity of continued creation of primitive "Monads".

Denies need for new powers and any principle of improvement.

Discusses gradations of intellectual powers.

Adaptive inferiority and extinction of groups of species and genera.

Asserts that climate is less important than the struggle with other organisms.

Suggests an experiment involving primroses and cowslips.

The chapter on hybridisation.

Rudimentary organs.

Gives opinion of Lamarck’s work.

Discusses events at Ilkley.

Thanks JP for bearing in mind his strong wish to learn any facts on inheritance at corresponding ages, and on correlation of growth.

JP’s case of teeth affected by syphilitic parents seems very curious. Would like to hear a few particulars when they meet.
