Summary

Sends GB a selection of reviews of the Origin from his collection of about 90, with his opinion of some of them.

Summary

His bad health continues.

Thirty-two plants have come up from the earth attached to partridge’s foot.

Origin to be published in Italian.

Owen was wrong: Origin will not be forgotten in ten years.

Summary

Natural selection implies that a form remains unaltered unless an alteration is to its benefit. This is not inconsistent with some forms remaining stable for long periods. Natural selection must at present be grounded entirely on general considerations. Of details we are still greatly ignorant.

Summary

Discusses experiments that WBT will undertake to investigate whether particular pigeon and poultry crosses produce sterile hybrids.

Summary

Discusses methods of pollination in orchids.

Thinks RT should investigate Physianthus to see if it requires insect aid for fertilisation as the Asclepiadaceae do.

Summary

Thanks for news about fertilisation of Melastomataceae.

Discusses fertilisation of orchids.

Mentions observations by John Scott.

Asks about "bud-variations".

Summary

Lyell’s Antiquity of man lacks originality.

Statements in Lyell provoke CD to determine exact publication date of Origin and JDH’s introductory essay [to Flora Tasmaniae].

CD now believes in repeated periods of global cooling and migration.

Summary

Thanks for information about Pliocene mammal. Interested in relating process of formation to duration of the species. Oswald Heer’s view that species suddenly formed surely false.

Bad summer with much sickness. Going to Malvern [for water-cure] for a month.

Muddled over phyllotaxy and made out nothing.

Summary

Comments at length on CL’s book [Antiquity of man (1863)]. CD is "greatly disappointed that you have not given judgment and spoken fairly out what you think about the derivation of species".

Lists large number of queries concerning minor points.

Praises especially the chapters on language and glaciers.

Comments on the temperature of Africa during the glacial period, especially with regard to the views of Hooker.

Mentions Owen’s paper on the aye-aye [Rep. BAAS 32 (1862) pt 2: 114–16].

Summary

Remarks on the influence of pollen of one species or variety on the seed and fruit of another while still attached to the female plant. Refers to a remarkable case previously given by D. Beaton and asks whether Beaton will repeat the details.

[CD’s letter is followed by notes by D. Beaton in which he answers CD’s question, dissociating himself from some of his remarks, and in particular denying C. F. v. Gärtner’s claim that colour of one variety of pea can be changed by the direct action of the pollen of a different variety.]

Summary

CD overwhelmed by THH’s praise.

Agrees with his reservations about species theory but not wholly about sterility and gives his reasons for differing.

On Natural History Review, Hugh Falconer, and R. Owen.

Has written a review [Collected papers 2: 87–92] of H. W. Bates’s paper ["Contributions to an insect fauna of the Amazon valley", Trans. Linn. Soc. Lond. 23 (1862): 495–566].

Summary

Discusses geology of Brazil.

Asks for Brazilian stamps for his son.

Summary

Indignant over Owen’s conduct as described in Hugh Falconer’s article on elephants ["On the American fossil elephant of the regions bordering the Gulf of Mexico", Nat. Hist. Rev. (1863): 43–114].

Summary

Particularly interested in TR’s information about peaches. Accepts offer of double-flowering peach-trees.

Will build a small hothouse for experiments.

Summary

Herbert Spencer’s work disappointing – "all words & generalities".

Summary

CD does not think he could be wrong about the stigma of Bolbophyllum.

Will not write up Drosera for years.

Praises JS’s experiments. Invites him to send a paper to Linnean Society.

L. C. Treviranus says all species of Primula present two forms except P. longiflora.

Summary

Recommendation of the admission of George Maw to the fellowship of the Geological Society of London.

Summary

Responds to JDD’s letter [3845].

Discusses his own poor health.

"Man is our great subject at present."

Lyell’s book [Antiquity of man (1863)] sold 4000 copies on day of sale.

"The fossil bird [Archaeopteryx] … is a grand case for me." Wishes a skeleton could be found in the "so-called red sandstone foot-step beds".

Summary

Discusses hybrid strawberry–raspberry

and his research on Primula and Linum.

Suggests breeding experiments.

Doubtful about Donald Beaton’s statement about Pelargonium.

Mentions experiments on peloric flowers.

Summary

Attacks the doctrine of "heterogeny" (spontaneous generation during each geological period) as completely lacking in evidence.

Defends natural selection as connecting large classes of facts in natural history. That certain forms have not changed since remote epochs is not an objection of any force.
