As →we may infer that our domestic animals were originally chosen by uncivilised man because they were useful and →bred readily under confinement, and not because they were subsequently found capable of far-extended transportation,

the common and extraordinary capacity in our domestic animals of not only withstanding the most different

climates

but of being perfectly fertile (a far severer test) under them, may be used as an argument that a large proportion of other

could easily be brought to bear widely different climates. We must not, however, push the foregoing argument too far, on account of the probable origin of some of our domestic animals from several wild

stocks;

stocks:

the blood, for instance, of a tropical and arctic wolf →or wild dog may perhaps be mingled in our domestic breeds. The rat and mouse cannot be considered as domestic animals, but they have been transported by man to many parts of the world, and now have a far wider range than any other
