[1]The white, pied, and “Japan” individuals are not more different from the type than some variations occurring in wild birds.
[2]This short-legged type of dog is sometimes seen among the ownerless and unselected pariah dogs of Indian towns; and a short-legged variety of the fowl may occur sporadically in Zanzibar, where the long-legged Malay is the prevalent breed.
[3]“Effected” appears in the earlier editions, but in the later editions has given place to “affected,” probably a printer’s error.
[4]Some egrets, such as the rock-egrets (Demiegretta) of eastern tropical coasts, are normally grey, but may be white, and this whiteness may be confined in individuals to the young or adult states.
[5]After years of observation of these Indian geese, Finn is convinced they are now, at all events, pure Chinese; it is possible that they really were hybrids in Blyth’s time, but that fresh importations of geese from China, such as still occur, may have ultimately swamped the blood of the common goose. The fertility of the hybrid geese was, however, known to such early writers as Pallas and LinnÆus. Darwin himself, at a later date, bred five young from a pair of such hybrids (Nature, Jan. 1, 1880, p. 207).
[6]In this chapter we use the word Neo-Darwinism in its usually-accepted sense, i.e. as a name for that which should be called Wallaceism, for the doctrine of the all-sufficiency of natural selection.

[8]Even these eggs, closely though they resemble in colouring the shingle, etc., on which they are laid, are discovered and eaten by gulls, as Mr A. J. R. Roberts points out in The Bird Book.
