Summary

Reports further observations on contraction of platysma. Has been assisted by J. Wood. [See Expression, pp. 302, 303.]

Summary

Thanks WO for information on platysma, which he did not know could be brought into voluntary action. Is coming to believe it has nothing to do with expression.

On the relation between white colouring and susceptibility to poisonous plants, CD suggests WO send his paper to J. Wyman and propose he investigate whether white as well as black pigs will eat paint-root.

Summary

Thanks WO for valuable letter. Feels he need not trouble any more about platysma. If WO ever sees someone suffering great fear, CD asks him to observe the neck.

Hopes to visit WO when next in London.

Summary

Has sent copy of his paper to Asa Gray.

Melastomad flowers are strikingly neglected by pollinators.

Murray has ordered many illustrations for HWB’s Naturalist on the river Amazons.

Summary

Thanks WO for a paper and for information about platysma. Has asked several persons to observe the muscle during a shivering fit, but all have failed.

Summary

Asks WO to act out the sudden discovery of a dreadful object and to observe whether his platysma contracts. CD has found in his notes that it is never contracted in cases of severe dyspnoea [Expression, p. 301].

Summary

Thanks for note. Believes agreement with Henry Colburn does not cover 2d ed. of Journal of researches. Regrets Murray’s Colonial Library series will require one-fifth reduction of text; will consult Lyell on how to reduce scientific part. Prefers that JM consult with Colburn, but in case he declines, encloses draft of letter he would send to Colburn. Anticipates co-operation of Colburn, as he has paid CD nothing for 1st ed. of Journal.

Summary

Suggests a memorial from Huxley, Murchison, and other geologists on the Gallegos fossils. He will speak privately to Duke of Somerset.

Summary

Has heard that Variation sold the whole edition of 1500 copies in a week [see 5844]. Has done him a world of good. Pall Mall Gazette has review which pleased him exceedingly [see 5874].

Summary

CD is glad there is to be an American edition of Origin printed from the corrected 2d English edition.

Summary

Regrets sending his MS missing two pages.

Has proofs of his paper on the monoecious spikes of maize [Edinburgh New Philos. J. 2d ser. 19 (1864): 213–20].

J. H. Balfour objected to notion of maize descent from a hermaphrodite.

Reading of JS’s paper on Selaginella hybrid [Edinburgh New Philos. J. 2d ser. 19 (1864): 192–9] deferred until March. Believes it is first example of experimentally produced hybridity in higher cryptogams.

Summary

Opinions on the Origin: AG thinks it masterly; Agassiz considers it very poor.

Summary

French translation of Orchids is published.

Summary

Sends fresh plants from France: Lythrum graefferi, Romulea.

Does CD know Pulmonaria is dimorphic?

Summary

CD will supply the sheets of the new edition of the Origin [5th ed. (1869)] if JD goes ahead with his work [Kurze Darstellung der Lehre Darwin’s über die Entstehung der Arten der Organismen (1870)]. Has no objection to JD’s quoting him, but wonders whether the German publisher of Origin might not feel injured.

Summary

Delighted with mechanisms of Salvia and Viola. How can anyone who compares structure of Viola cornuta and common violet still suppose them to be separate creations?

Summary

The question is whether additional digits possess power of regrowth beyond the ordinary. James Paget has convinced CD that they do not. CD must alter what he has published. [See Variation, 2d. ed., 2: 459.]

Summary

JS criticises natural selection as based on an innate "continuously watchful selective principle".

Seeks seed of wild Rocky Mountain maize.

What is CD’s view on origin of maize?

Seeks information on self-sterility of Passiflora and Lobelia.

Weeping habit of trees.

Intended to say bisexual plants presented more established varieties than unisexual, not that they are more variable.

Explains his opinion that homomorphically fertilised Primula will produce only their own form. Is trying homomorphic crosses with different coloured Primula varieties.

Asks to read Asa Gray’s 2d review of Orchids.

Has finally successfully fertilised Gongora, but it was done by unnatural means.

Summary

Further additions and corrections for American Origin.

Views of Owen, G. H. K. Thwaites, and W. H. Harvey on CD’s theories.
