From Charles Wade Crump to Edward Blyth   [before 8 January 1856]

Summary

Reports upon a breed of wild cattle found in southern India. The herd is reputedly descended from a wild, red bull that mated with tame cows.

From Edward Blyth   21 April 1855

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.

From Edward Blyth   4 August 1855

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.

From Edward Blyth   22–3 August 1855

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.

From Edward Blyth   7 September [1855]

Summary

Comments on the ease with which different species of Felis can be tamed.

Asian species of wild cattle.

Variation in colour of jackals.

Discusses the difficulties of differentiating between varieties and species. EB recommends Herman Schlegel’s definition of species [in Essay on the physiognomy of serpents, trans. T. S. Traill (1843)]. Problems of defining species of wolves and squirrels. Pigeons and doves afford an illustration of "clusters of species, varieties, or races". Various pigeons have local species in different parts of India and Burma, some of which interbreed where their ranges cross; as do the local species of Coracias [see Natural selection, p. 259].

From Edward Blyth   [22 September 1855]

Summary

Gives extract from a letter from Capt. R. Tickell: rabbits are not bred by the Burmese; common European and Chinese geese are bred but have probably only recently been introduced.

EB gives references to works illustrating the dog-like instinct of N. American wolves.

Discusses reason and instinct; ascribes both to man and animals. Comments on various instincts, e. g. homing, migratory, parental, constructive, and defensive. Reasoning in animals; cattle learning to overcome fear of passing trains.

Hybrid sterility as an indication of distinct species. Interbreeding as an indication of common parentage.

Enlarges upon details given by J. C. Prichard [in The natural history of man (1843)].

Adaptation of the two-humped camel to cold climates. Camel hybrids.

Doubts that domestic fowl or fancy pigeons have ever reverted to the wild.

Feral horses and cattle of S. America.

Believes the "creole pullets" to be a case of inaccurate description.

Variations in skulls between species of wild boar.

Pigs are so prolific that the species might be expected to cross.

Milk production of cows and goats.

Sheep and goats of lower Bengal.

Indian breeds of horses.

Variation in Asiatic elephants.

Spread of American tropical and subtropical plants in the East.

From Edward Blyth   8 October 1855

Summary

Encloses two sets of notes [see 1761 and 1762]. EB believes that as a general rule species do not inter-mix in nature whereas varieties, descendants of a common stock, do. Origin of varieties. Geographically separated species are sometimes obviously distinct and sometimes apparently identical. EB does not believe that species or races of independent origin need necessarily differ. Local distribution of species of black cockatoo contrasts with the widespread white cockatoo. The occurrence of distinct but related species in different regions of a zoological province, preserved because of geographical barriers. Instances of interspecific hybrids and intraspecific sterility. Local varieties of species. Varieties are subdivisions of the main branches of the tree of organisms, dividing irregularly but remaining independent of the twigs from another branch.

From Edward Blyth [30 September  or 7 October 1855]

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.

From Edward Blyth   [1–8 October 1855]

Summary

Notes on Lyell’s Principles, vol. 2.

EB does not believe in connecting links between genera; there is no tendency to gradation between groups of animals.

Does not believe shortage of food can directly produce any heritable effect on size.

Comments on significance of variations discussed by Lyell. Variation in dentition and coloration.

Behaviour of elephants and monkeys.

When varieties are crossed EB considers that the form of the offspring, whether intermediate or like one or other of the parents, depends upon how nearly related the parents are.

Thinks that in the struggle for existence hybrids, and varieties generally, must be expected to give way to the "beautiful & minute adaptation" of the pure types.

Colours of Indian birds.

Vitality of seeds.

Variation among palms.

Fauna of Malaysia and New Zealand. Ranges of bird species.

Summary

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.

From Edward Blyth   8 December 1855

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.
