Summary

Response to Origin. Praise for summary of chapter 10 and chapter 11.

The dissimilarity of African and American species is ‘necessary result of “Creation” adapting new species to the pre-existing ones. Granting this unknown & if you please miraculous power acting’.

C. T. Gaudin writes of Oswald Heer’s finding many species common between Miocene floras of Iceland and Switzerland. Interesting for CD’s migration theory.

Summary

Sends a Corydalis.

Hermann Crüger’s paper [see 4394] splendid, but he has made a mess of propagating Cinchona in Trinidad.

JDH’s opinion of Germans.

Summary

Agassiz denounces Origin as "atheistical";

AG is currently reviewing it [in Am. J. Sci. 2d ser. 29 (1860): 153–84].

Jeffries Wyman praises it, though not a convert.

Summary

Cancelled: Known only from reference in letter to Charles Lyell, 11 October [1859]

Summary

Will be proud to publish CD’s new work on domestic animals [Variation]. Will announce it as the complement of the Origin. Advises on woodcuts; does not wish to limit number; agrees to CD’s suggestions for artists.

Summary

Has a small living at Norton Canon.

Will visit Charles Whitley next week.

Summary

Wishes CD would enlarge on the doctrines of [Pyotr Simon] Pallas about the various races of dogs having come from several distinct wild species or sub-species.

Suggests organisms have a latent principle of improvement which is brought out by selection or breeding.

Summary

Sends a correction for Origin reprint.

Summary

Sends some bees CD requested

and discusses the differences among several animal species on islands of the West Indies.

Summary

Questions CD’s view in Origin that domestic dogs are not descended from a single stock. Occasional crossings of domestic stock with wild species could explain cases of reversion towards wild specific forms. CD’s views on hybridity do not then have to be contradicted in constructing an ancestral stock.

Summary

Forwards letter from Asa Gray.

Bentham is very agitated by Origin. CD over-emphasises natural selection. His theory accounts for too much and would be improved by unburdening it of natural selection.

Summary

Wishes CD could publish Origin with footnotes.

Increases in bird populations: starlings are increasing, but AN cannot give reason; mistletoe-thrush increasing but not ousting song-thrush. Doubts trustworthiness of [George?] Edwards, CD’s authority in Origin on this matter [see Origin, 6th ed., p. 59].

AN opposed to bird protection legislation to prohibit egging. Argues egging does not decrease number of birds.

Summary

Thinks a new U. S. edition of Origin is needed.

Gives observations on the climbing habits of Bignonia capreolata.

Summary

Praises the Origin: a "splendid case of close reasoning".

Objects to CD’s having ignored Lamarck and Geoffroy Saint-Hilaire.

Thinks CD should omit mentioning problem of explaining the eye at the beginning of chapter 14. Suggests rewording several passages.

Thinks want of peculiar birds in Madeira a difficulty, considering presence of them in Galapagos.

Has always felt that the case of man and his races is one and the same with animals and plants.

Summary

Describes some cases of geographical distribution of butterflies. Raises the perplexing question of the distribution of Pyrameis atalanta in Europe and P. calliroe in the Canaries.

Summary

It is strange that Agassiz, who is for the "sanctity of species", should favour Pallas’s view of hybrid origin of domestic dog.

CL has not meant to advocate successive creation of types but to question assumption that all mammals descended from single stock. Why should a Triassic reptile or bird not move towards mammalian form because an ancestral marsupial has appeared? Believes recent appearance of rodents and bats in Australia explains their lack of development.

Can CD supply a reference on plant extinction on St Helena?

Believes marsupials better adapted for surviving drought in Australia than higher mammals.

Will not press argument about lack of development of mammalian forms on islands, but CD should note objection.

Does CD’s belief in multiple origin of dogs affect faith in single primates in different regions?

Does time lapse between putative independently descended mammalian forms mean first form will "keep down" later incipient one? Thus Homo sapiens has prevented improvement of other anthropomorphs; bats and rodents on islands would prevent improvement of lower forms into mammalian.

Summary

Reminds CD of their acquaintance at Ilkley Wells; encloses portrait of self;

describes the topography, trade, commerce, produce, and population of São Paulo province.

Sends pieces of rock blasted for railway for CD to analyse.

Summary

The antlers of 800 deer of the glacial period have been found in a cave. They show great variety of form, but gradation from one to the other can be traced when all are laid out. Suggests CD study changes that have taken place in the species since glacial period.

Has ordered the wicked book [Origin] CD has been so long a-hatching.

Summary

Thanks for Lythrum paper [Collected papers 2: 106–31].

T. S. Cobbold’s book on the Entozoa [1864].

Remarks on development of the tapeworm.

Summary

Lists land birds of Galapagos and discusses their distribution on mainland of S. America.
