[36] Sclater, in ‘Proc. Zoolog. Soc.,’ 1862, p. 163: this species is the Ghor-Khur of N.W. India, and has often been called the Hemionus of Pallas. See also Mr. Blyth’s excellent paper in ‘Journal of Asiatic Soc. of Bengal,’ vol. xviii., 1860, p. 229.
[37] Another species of wild ass, the true E. hemionus or Kiang, which ordinarily has no shoulder-stripes, is said occasionally to have them; and these, as with the horse and ass, are sometimes double: see Mr. Blyth in the paper just quoted and in ‘Indian Sporting Review,’ 1856, p. 320: and Col. Hamilton Smith in ‘Nat. Library, Horses,’ p. 318; and ‘Dict. Class. d’Hist. Nat.,’ tom. iii. p. 563.

[41] ‘The Poultry Book,’ by Mr. Tegetmeier, 1866, pp. 119, 163. The author, who remarks on the two negatives (‘Journ. of Hort.,’ 1862, p. 325), states that two broods were raised from a Spanish cock and Silver-pencilled Hamburgh hen, neither of which are incubators, and no less than seven out of eight hens in these two broods “showed a perfect obstinacy in sitting.” The Rev. E. S. Dixon (‘Ornamental Poultry,’ 1848, p. 200) says that chickens reared from a cross between Golden and Black Polish fowls, are “good and steady birds to sit.” Mr. B. P. Brent informs me that he raised some good sitting hens by crossing Pencilled Hamburgh and Polish breeds. A cross-bred bird from a Spanish non-incubating cock and Cochin incubating hen is mentioned in the ‘Poultry Chronicle,’ vol. iii. p. 13, as an “exemplary mother.” On the other hand, an exceptional case is given in the ‘Cottage Gardener,’ 1860, p. 388, of a hen raised from a Spanish cock and black Polish hen which did not incubate.
