[11] Sir R. Schomburgk has given me information on this head. _See also_ ‘Journal of R. Geographical Soc.’ vol. xiii. 1843, p. 65. [12] ‘Domestication of Animals:’ Ethnological Soc., Dec. 22nd, 1863. [13] ‘Journal of Researches,’ etc., 1845, p. 393. With respect to _Canis antarcticus, see_ p. 193. For the case of the antelope, _see_ ‘Journal Royal Geograph. Soc.,’ vol. xxiii. p. 94. [14] 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 Esquimaux 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. [15] ‘Fauna Boreali-Americana,’ 1829, pp. 73, 78, 80. Nott and Gliddon, ‘Types of Mankind,’ p. 383. The naturalist and traveller Bartram is quoted by Hamilton Smith, in ‘Naturalist 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._) [16] I quote this from Mr. R. Hill’s excellent account of the Alco or domestic dog of Mexico, in Gosse’s ‘Naturalist’s Sojourn in Jamaica,’ 1851, p. 329. [17] ‘Naturgeschichte der Säugethiere von Paraguay,’ 1830, s. 151. [18] Quoted in Humboldt’s ‘Aspects of Nature’ (Eng. trans.), vol. i. p. 108. [19] p.t’s ‘Travels in Hungary and Transylvania,’ vol. i. p. 501. Jeitteles ‘Fauna Hungariæ Superioris,’ 1862, s. 13. _See_ Pliny ‘Hist. of the World’ (Eng. trans.), 8th book, ch. xl., about the Gauls crossing their dogs. _See also_ Aristotle ‘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. [20] 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.
