Writes of WED’s progress at school and events at home.

Discusses pigeons, with which he is "getting on splendidly".

Preparing paper on seed-soaking for Linnean Society ["Action of sea-water on seeds", Collected papers 1: 264–73]. Wants to use MJB’s results. Lost ardour when he found seeds would not float.

Has grown MJB’s purest pea seeds and got a few variants. Gärtner’s experiments suggest direct action of pollen, but CD thinks it is "mere variation".

JL is studying Cynipidae. CD sends galls for his examination.

Hopes GHKT will publish on variations in plant species at different elevations. Asks about variations among plants on heights of Ceylon.

Promises to publish on the species question.

Asks for pigeons’ skins from India or Ceylon, and for ducks’ skeletons. Mentions help promised by E. F. Kelaart.

Thanks SC for his interesting account of the state of the colony. SC was wise to settle there where his sons have much better prospects.

Has finished his book on barnacles [1854]. Royal Medal awarded him chiefly for this work.

Asks SC whether he has observed any odd imported breeds of poultry, for his work on variation of species.

Thanks for copy of HS’s Principles of psychology [1855].

Arranges an appointment.

Believes WDF’s case of mongrel Scotch deerhound is very valuable for him.

Mentions his work on pigeons and chickens.

Fears sometimes he will break down: "My subject gets bigger and bigger".

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.

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.

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.

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?

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.
