And so of hounds, setters, greyhounds, and all the varieties of domestic dogs, so long as they are interbred among themselves; but the moment they are associated w' Ji the wolf, fox, jackal, dingo, or any of the congenerous though distinct races, they will breed with them, it is true, but the progeny will be truly hybrid and barren. If, therefore, it should be proved on experiment, that the various distinct species of the Salmonidce, as they are now held to be, will, when interbred, produce young capable of reproduction, it would go very far to establish the fact that the distinctions are not distinctions, but merely varieties. I must not, however, be understood as saying that the success of experiments, and the establishment of such a result as I have supposed, would go at all to prove that such intermixture of varieties occurred, or such cross-breeds were produced, in a state of nature; far from it. We know, that in vegetables, hybrids can be, and are, readily pro- duced by artificial means, which will not occur once in a century, per- haps never would occur at all, were the plants left to the operation of nature. Nature abhors monstrosities; and the proverb that the " cat will follow kind" is of older wisdom than Will Shakspoarc's. Man's freaks have raised mongrels between the lion and the tigress; nature's, so far as wo kncv, or can conjecture, never. And always in a wild state a hundred circumstances, such as different
