[15] Sir R. Schomburgk has given me information on this head. See also 'Journal of R. Geograph. Soc.,' vol. xiii., 1843, p. 65.

[18] The authorities for the foregoing statements are as follow:—Richardson, in 'Fauna Boreali-Americana,' 1829, pp. 64, 75; Dr. Kane, 'Arctic Explorations,' 1856, vol. i. pp. 398, 455; Dr. Hayes, 'Arctic Boat Journey,' 1860, p. 167. Franklin's 'Narrative,' vol. i. p. 269, gives the case of three whelps of a black wolf being carried away by the Indians. Parry, Richardson, and others, give accounts of wolves and dogs naturally crossing in the eastern parts of North America. Seeman, in his 'Voyage of H.M.S. Herald,' 1853, vol. ii. p. 26, says the wolf is often caught by the Esqimaux for the purpose of crossing with their dogs, and thus adding to their size and strength. M. Lamare-Picquot, in 'Bull. de la Soc. d'Acclimat.,' tom. vii., 1860, p. 148, gives a good account of the half-bred Esquimaux dogs.

Lib.,' vol. x. p. 156. A Mexican domestic dog seems also to resemble a wild dog of the same country; but this may be the prairie-wolf. Another capable judge, Mr. J. K. Lord ('The Naturalist in Vancouver Island,' 1866, vol. ii. p. 218), says that the Indian dog of the Spokans, near the Rocky Mountains, "is beyond all question nothing more than a tamed Cayote or prairie-wolf," or Canis latrans.

See Pliny, 'Hist. of the World' (Eng. transl.), 8th book, ch. xl., about the Gauls crossing their dogs. See also 'Hist. Animal.' lib. viii. c. 28. For good evidence about wolves and dogs naturally crossing near the Pyrenees, see M. Mauduyt, 'Du Loup et de ses Races,' Poitiers, 1851; also Pallas, in 'Acta Acad. St. Petersburgh,' 1780, part ii. p. 94.
[24] I give this on excellent authority, namely, Mr. Blyth (under the signature of Zoophilus), in the 'Indian Sporting Review,' Oct. 1856, p. 134. Mr. Blyth states that he was struck with the resemblance between a brush-tailed race of pariah-dogs, north-west of Cawnpore, and the Indian wolf. He gives corroborative evidence with respect to the dogs of the valley of the Nerbudda.
