Note 2 — Chapter I · DOMESTIC DOGS AND CATS.

Pallas, I believe, originated this doctrine in ‘Act. Acad. St. Petersburgh,’ 1780, Part ii. Ehrenberg has advocated it, as may be seen in De Blainville’s ‘Ostéographie,’ p. 79. It has been carried to an extreme extent by Col. Hamilton Smith in the ‘Naturalist Library,’ vols ix and x. Mr. W. C. Martin adopts it in his excellent ‘History of the Dog,’ 1845; as does Dr. Morton, as well as Nott and Gliddon, in the United States. Prof. Low, in his ‘Domesticated Animals,’ 1845, p. 666, comes to this same conclusion. No one has argued on this side with more clearness and force than the late James Wilson, of Edinburgh, in various papers read before the Highland Agricultural and Wernerian Societies. Isidore Geoffroy Saint-Hilaire (‘Hist. Nat. Gén.,’ 1860, tom. iii. p. 107), though he believes that most dogs have descended from the jackal, yet inclines to the belief that some are descended from the wolf. Prof. Gervais (‘Hist. Nat. Mamm.’ 1855, tom. ii. p. 69, referring to the view that all the domestic races are the modified descendants of a single species, after a long discussion, says, “Cette opinion est, suivant nous du moins, la moins probable.”
