Gives references to William Allen’s narrative of the Niger expedition [William Allen and T. R. H. Thompson , A narrative of the expedition sent by Her Majesty’s Government to the river Niger in 1841 (1848)]: common fowl returning to wildness, details of domestic sheep, ducks, and white fowl.

Occurrence of cultivated plants from Europe in India; success of cultivation. Ancient history of cultivated plants.

[CD’s notes are an abstract of this memorandum and indicate that it was originally 20 pages long.]

History of the rose in India.

Looks forward to reading what Hooker and Thompson say on species and varieties in their Flora Indica [1855].

Domestication of the turkey in America. The Peruvians had domestic dogs. W. W. Robinson of Assam reports that otters are extensively trained for fishing but cormorants never are. Gives Robinson’s comments on local domestic geese, rabbits, and cats.

EB has skins of jungle fowl from different localities to send.

What does CD think of A. R. Wallace’s paper in the Annals & Magazine of Natural History ["On the law which has regulated the introduction of new species", n.s. 16 (1855): 184–96]? EB considers it good on the whole.

Japanned variety of peacock.

Regional variations in bird species.

EB has little faith in the aboriginal wildness of the Chillingham cattle.

Races of humped cattle of India, China, and Africa.

Indian and Malayan gigantic squirrels, with various races remaining true to their colour, would afford capital data for Wallace, as would the local varieties of certain molluscs. Has Wallace’s lucid collation of facts unsettled CD’s ideas regarding the persistence of species?

Bengal hybrid race of geese is very uniform in colour and as prolific as the European tame goose [see Natural selection, p. 439].

Will see what he can do for CD with regard to domestic pigeons.

Encloses "notes for Mr. D" [see 1818] and a memorandum on the wild cattle of southern India [see 1819].

Breeds of silky fowl of China and Malaya. Black-skinned fowl.

Doubts any breed of canary has siskin blood; all remain true to their type.

Wild canary and finch hybrids.

Hybrids between one- and two-humped camels.

Does not regard zebra markings on asses as an indication of interbreeding but as one of the many instances of markings in the young which more or less disappear in the adult.

Crossing of Coracias species at the edges of their ranges.

Regional variations and intergrading between species of pigeons.

Regards the differences in Treron as specific [see Natural selection, p. 115 n. 1].

Gives other instances of representative species or races differing only in certain details of colouring.

Believes the goldfish originates from a wild, gold variety of Chinese carp.

Gallinaceous birds.

Crested turkeys.

EB divides the gallinaceous birds into five families on anatomical distinctions.

Wild dog species of India and Asia; ranges of some species, specific identity of others.

The fauna of the Seychelles.

Breeding of fowls in India and Africa.

Occurrence of turkeys in Africa.

Refers to some of his own papers giving fuller details of points raised previously.

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.

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.]

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.

Zebra-striped asses.

Markings of a Bengal jungle cock.

Refers to some of his own articles on birds in India.

Reports the arrival of the "glorious garrison of Lucknow". The "wonderful superiority of the European to the Asiatic" made the success of the insurrection inconceivable.

Gives some observations on birds; has forwarded a box of specimens.

Sends extract from a correspondent’s letter reporting birds carried to Mauritius from Madagascar by winds.

On his breeding of Jacobin pigeons. How reciprocal crosses to produce mules work among canaries, goldfinches, linnets, and green linnets.

Will soon forward copies of Cottage Gardener for June.

Discusses the difficulties of breeding mules by crossing canaries and finches.

Writes regarding CD’s query on yellow-billed cuckoo and the laying of eggs in other birds’ nests.

Discusses the relative growth of native and foreign weeds.

Responds to CD’s questions about mountain vegetation of the Cape of Good Hope. The distribution of some plants provides problems for both migration and special creation hypotheses.

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.

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.

Reports his observations on an ants’ nest.
