Asks WBT to try to purchase some specific pigeons.

Thanks MJB for information which he is including in his article for the Linnean Society.

Refers to the peas "which produce the black or intensely purple pods". [See 1834 and 1836.]

Discusses various pigeons and would welcome receiving any odd breed. Some pigeons have died from overeating bag salt.

Gives references to works on fowls and pigeons.

Observations on Gallinaceae.

Musk ox skull from southern England is additional evidence for Agassiz’s glacial period. Owen is mistaken in calling it a buffalo.

EB describes the buffalo proper.

Will send domestic pigeon specimens.

Believes pigeons were not bred in India before the Mohammedan conquest. Describes Indian breeds.

Believes the ass is an African rather than an Asian production. Discusses various species of ass and their distribution.

Wild horned cattle on borders of Pilibhit and Shahjahanpur.

[Notes received by CD on 6 May 1856.]

Thanks for proof sheets of Lake Ngami: or, exploration and discoveries during four years’ wanderings in the wilds of South Western Africa (Andersson 1856).

Is very grateful for the information CJA has provided about cattle in South Africa, and wishes to ask further questions about native breeds.

Invitation to THH and wife to come to Down to meet H. C. Watson, T. V. Wollaston, and the Hookers.

Reports observations on Indian pigeons from David Scott at Hansi. EB adds remarks on Indian breeds he has encountered. Suggests Egypt, Turkey, and Syria would be good places from which to obtain specimens. Believes domestic races are all descended from Columba livia; their calls are all similar and they pair indiscriminately.

Guinea-fowl.

Reminds WBDM of his promise of information about the quartz boulders and an iceberg with fragment of rock seen in southern ocean.

Sends other questions [on separate sheet (missing)] which WBDM will think ridiculous, but all bear on plants and animals under domestication.

European men choose partners for different reasons. Savages select more for bodily attraction than facial beauty.

His thanks for the extracts sent by SB.

Mustering support at Royal Society Council for John Lindley’s Copley Medal. CD thinks Albany Hancock deserves a Royal Medal.

Arrangements for visit of Huxleys to Down on 26 Apr.

CD asks whether New Zealand tribes have an idea of beauty in women which is "like ours"; WBDM answers, "Yes".

Thanks WBDM for his reply [missing] to CD’s previous letter [1603].

Asks for more details on the erratic blocks.

Asks also if there is good evidence that there formerly existed [in New Zealand] some animal with hair, like an otter or beaver.

Finally, do the uncivilised natives have the same ideal of [human] beauty as Europeans?

Discusses the flora of Porto Santo in relation to that of Madeira. While these islands have some 20 endemic species in common, there are 7 or 8 species endemic to Porto Santo alone, and 25 common to Porto Santo and Europe that are not found on Madeira. Believes the great difference in soil and climate is enough to explain this: plants common on one island cannot be made to grow on the other. Believes J. D. Hooker has underestimated the number of species endemic to Madeira. There are some remarkable endemic species of common plants in the Dezertas.

The eel is the only freshwater fish on Porto Santo and Madeira.

Thanks HTS for Entomologist’s Weekly Intelligencer [no. 2, 12 Apr 1856]. Agrees with his remarks [in "Why did Mr Westwood get the Royal Medal?"], but explains that a change in rules for awarding the Royal Medal has been made. Earlier it had to be given for publications in Philosophical Transactions of the Royal Society, which explains small number of entomologist recipients.

Is interested by what CD tells him about his researches and speculations on species, variation, and distribution. Hopes he will not give up the idea of publishing his views. Advises CD on need for caution and candour. Raises some difficulties with "specific centre" theory of distribution.

Invites him to visit. JDH and one or two others coming.

CD writes on geographical distribution – "a grand game of chess with the world for a board".

Gives his hypothetical explanation why zoology of Cape [of Good Hope] is not so peculiar as its botany: it was once a group of islands – later united.

Tries hard to set forth the difficulties of his [species] theory.

Tells CJFB in confidence of his theory of the glacial epoch and its effect on plant distribution, such as identical species being found on summits of mountains in the tropics. Invites him to attack his "doctrine".

Speculates about cause of inclination in unusual columns of lava. Suggests CL check with William Hopkins about sliding movements in viscid matter.

Comments on CL’s expedition to Madeira.
