Summary

Gives extracts from a letter by Thomas Hutton.

Rabbits are kept (generally by Europeans) in the NW. provinces and breed freely. Canaries are not well adapted to the climate. Reports on domestic cats and pigeons of the area. EB gives references to further information on cats, pigeons, and silkworms.

Summary

Indigenous domestic animals of the New World.

Relationship of Newfoundland and Esquimo dogs to the wolf. Dogs like the Esquimo occur in Tibet and Siberia. Indian pariah dogs and jackals occasionally interbreed.

Describes domestic cats of India; reports cases of their interbreeding with wild cats. Wild cats are tamed for hunting.

Races of silkworm in India are crossed [see 1690].

Domesticated plants, fish, and birds of India.

Comments on local races and species of crows; it is impossible to trace a line of demarcation between races and species.

Variation in the ability of hybrids to propagate.

Indian cattle breeds; differences between Bos indicus and Bos taurus.

Is not satisfied that aboriginally wild species of horse and ass exist.

Believes all fancy breeds of pigeon originated in the East. Wild ancestors of pigeons, ducks, geese, and fowls. Interbreeding of wild species of pheasant.

Summary

Origin of domestic varieties. EB ascribes "abnormal" variations to man’s propagation of casual monstrosities; believes "normal" variations, e.g. European races of cattle, are a consequence of man’s selecting the choicest specimens. Gives examples of "abnormal" variations; they give rise to features that have no counterpart among possible wild progenitors. Divides domestic animals into those whose origin is known and those whose origin is unknown. Considers that the wild progenitors of nearly all domestic birds are known. Fowls and pigeons show many varieties but if propagated abnormalities are ignored each group can be seen to be variations of a single species, the ancestors of which can be recognised without difficulty. Discusses varieties and ancestry of the domestic fowl. Variation in the wild; the ruff shows exceptional variability; other species of birds show variability in size of individuals. Remarks that markings sometimes vary on different sides of the same animal. Comments on the want of regularity in leaf and petal patterns of some plants. Discusses domestic varieties of reindeer and camels. Origin of humped cattle. Reports the rapid spread of a snail in lower Bengal that was introduced as a single pair five or six years previously.

Summary

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.

Summary

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.

Range of the fallow deer; its affinity to the Barbary stag.

Natural propensity of donkeys for arid desert.

Indian donkeys often have zebra markings on the legs.

Believes the common domestic cat of India is indigenous.

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.]

Summary

Sends a skeleton of a Bengal jungle cock.

Has never heard of trained otters breeding in captivity.

Introduced domestic rabbits are confined to the ports of India.

Canaries and other tame finches and thrushes brought into India do not breed well.

Origin of the domestic canary. Tendency of domesticated birds to produce "top-knot" varieties.

The tame geese of lower Bengal are hybrids; those of upper Bengal are said to be pure Anser cygnoides.

Wild Anser cinereus occur in flocks in the cold season.

Discusses at length different breeds of domestic cats and possible wild progenitors. Wild and domestic cats occasionally interbreed. The Angora variety breeds freely with the common Bengal cat and all stages of intermediates can be found.

Believes pigeons have been bred in India since remote antiquity.

Discusses whether mankind is divided into races or distinct species.
