Sends Madeira specimens, including frogs recently introduced into the island, and flourishing.

Has been invited to see Mr Bult’s pigeons.

Can FG use his influence with Rev. [Erhardt] to get information about domesticated poultry in Africa for CD?

Is grateful for SB’s note and assistance. Will call upon him in London in a fortnight.

"The Pigeons are all quite well".

Sends thanks to Mrs Cotton.

Has heard CD is much interested in questions relating to varieties and species. Mentions a case of a seminal variety of Colletia spinosa, described by John Lindley, which appears identical with another wild species of Colletia from S. America. Hopes CD will one day "enlighten us very much" on "the laws of species". There are many different views on the limits of species; M. F. Dunal made 50 species of Solanum which George Bentham considers are all varieties of S. nigrum.

Opposition to EB within the Asiatic Society.

Possibility of establishment of a zoological garden at Calcutta.

Has seen Gallus varius alive for the first time.

Will procure domestic pigeons for CD; could CD pay for them by returning hardy creatures, such as macaws and marmosets, which EB can sell for a high price in India?

Does not recall his authority for genealogy of the asses of Oman. If a genuine wild ass exists EB believes it will be in south Arabia.

Infertility of Irish and Devon red deer.

Details of an unusual species of wild dog.

Fertility of canine hybrids. General tendency toward hybrid sterility.

Has skins of hybrid Coracias and the parent species.

Wide-ranging species; skua found in Europe and Australia, but not in the tropics.

There is a possibility of establishment of a Government Museum at Calcutta, with which the Asiatic Society Museum would be merged. EB would like the curatorship but fears other possible applicants. Asks CD to represent him to W. H. Sykes.

Discusses the ancients’ awareness of various cats as deduced from the etymology of their names.

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.

Informs CD on age of land, freshwater, and marine Mollusca.

Reports on breeding experiments with various seeds: corn, aubergine, kidney beans, sugar-peas. Speculates that cause of changes in seed colour in sugar-peas may be mere variation rather than result of impregnation.

Is trying to procure some cocks for CD.

Believes Scotch deerhounds are mongrels.

TH believes that the progeny of hybrid crosses, in which a domesticated or "artificial" race is involved, tend to resemble the more "natural" of their parents [see Natural selection, p. 486].

Provides some information on local hybrid domestic geese [see Natural selection, p. 439] and pigeons.

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".
