Summary

Henslow’s long suffering.

Donald Beaton’s articles in Cottage Gardener clever but not to be trusted.

Summary

CD urges HWB to write on his travels;

asks for facts on domestic variations;

is pleased by HWB’s acceptance of the theory of sexual selection.

He still believes in migration from north to south during glacial age.

Hopes Bates will publish a paper on mimicry.

Summary

Discusses his observations at Glen Roy. Mentions glaciers seen by Hooker in the Himalayas. Discusses problems of glacier–lake theory.

Summary

Praises MS of first chapter of HWB’s book [The naturalist on the river Amazons (1863)]. Suggests he give common names and make comparisons to familiar English species to help readers. Suggests a few changes. Will speak strongly to Murray about publishing whenever HWB is ready.

Summary

Lindley suggests Gongora may be female Acropera.

CD’s orchid book nearly ready for press.

Discovers trimorphism in Lythrum is in H. Lecoq [Études sur la géographie botanique de l’Europe (1854–8)].

Summary

Comments especially on the "intermediate shelf" problem of Glen Roy; views of Jamieson and Milne. CD "cannot help a sneaking hope that the sea might have formed the horizontal shelves".

Summary

Thanks TD for his letter. Difficulties with CD’s theory are many and great, but CD thinks the reason is that we underestimate our ignorance. The imperfection of the geological record counts heavily for CD. His greatest trouble is weighing "the direct effects … of changed conditions of life without any selection, with the action of selection on mere accidental (so to speak) variability. I oscillate much on this head, but generally return to my belief that the direct [effects] … have not been great."

Is surprised that any one, like W. B. Carpenter, can go as far as to believe all birds may have descended from one parent, but will not go further and include all the members of the same great division. Such beliefs make "Divine mockeries" of morphology and embryology, the most important of all subjects.

Summary

Thanks AG for notes on hollies.

Replies to an argument for design. Feels it monstrous to consider orchids created as they are now seen, since every part reveals modification on modification.

Summary

Discusses progress of CL’s work [on Antiquity of man (1863)].

CD had not thought of subsidence in connection with "roads" of Glen Roy.

Discusses habits of ants.

Summary

Bates agrees with CD on neuter ants.

Orchids.

Repeating experiment of C. F. v. Gärtner to study Huxley’s idea of physiological species.

Summary

Thanks RC for "Ice and water" [in RC’s Edinburgh papers (1861)].

Comments on problem of scientific accuracy.

Discusses views of Thomas Davidson on the genealogy of brachiopods.

Summary

Thanks HWB for references.

Praises his paper ["Contributions to an insect fauna of the Amazon valley", read before Linnean Society, 21 Nov 1861, Trans. Linn. Soc. Lond. 23 (1862) : 495–566] which solves "one of the most perplexing problems which could be given to solve".

Discusses the difficulties of writing and expresses disappointment at Wallace’s book [Travels on the Amazon (1861)].

Summary

Recommends publisher for HWB; admires J. van Voorst but suggests Murray.

In reply to HWB’s letter [missing], comments on neuters and mimicry.

Summary

Thanks TCE for telling him of his crossed pigs. When they are grown, he would like to know whether they resemble each other.

Doubts the half-bred Gallus sonnerati will be productive, though he was assured many years ago that such a fertile half-breed once occurred.

Summary

Relates remark by J. S. Mill concerning soundness of logic and method of Origin.

Is at work [on Orchids and Variation].

Summary

Comments on MS of HF’s address ["On the method of Mr Darwin in his treatise on the origin of species", Rep. BAAS (1861) pt 2: 141–3]. "How odd it is that anyone should not see that all observation must be for or against some view if it is to be of any service."

Describes his health.

The response to his views in Germany, Holland, and Russia.

Summary

Thanks President and Council of Ethnological Society for his election.

Summary

Summary

Thanks HWB for information on Volucella, although he does not know when he will use it.

Is glad HWB is beginning his book.

CD is beginning work on his orchid book.
