But I may here state that, looking to the domestic dogs of the whole world, I have, after a laborious collection of all known facts, come to the conclusion that several wild species of Canidæ have been tamed, and that their blood, in some cases mingled together, flows in the veins of our domestic breeds.

The belief that our dogs are descended from wolves, jackals, South American Canidæ, and other species, suggests a far more important difficulty.

That the sterility is very slight between certain dogs and wolves and other Canidæ is shown by savages taking the trouble to cross them.

When compared with all known members of the family of Canidæ they betray a distinct and abnormal origin.

Seeing in how many characters the races of the dog differ from each other, and remembering Cuvier’s admission that their skulls differ more than do those of the species of any natural genus, and bearing in mind how closely the bones of wolves, jackals, foxes, and other Canidæ agree, it is remarkable that we meet with the statement, repeated over and over again, that the races of the dog differ in no important characters.
