Summary

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].

Summary

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".

Summary

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".

Summary

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.
