inhabitants of India take pleasure in having dog bitches lined by the
wild tigers, and to facilitate this union, they are in the habit of
tieing them when in heat out in the woods, so that the male tigers may
visit them. (See L. 8, c. xl.)

There is, however, but little doubt that the wolf and dog are varieties
of the same family, as they can he bred together, and their offspring
continuing the cross thus formed, will produce a race quite distinct
from the original. French writers do not hesitate at all upon this
point, but even assert that it is very difficult to take a she-wolf with
male dogs during the period of oestrum, parceque la veulent saillir et
covrir comme une chienne.

Baudrillart, in the "dictionaire des chasses," further remarks that the
mongrels produced by this connection are very viciously disposed and
inclined to bite.

The period of utero-gestation, and the particular mode of copulation in
the wolf, is the same as that of the canine family, which two
circumstances are certainly very strong presumptive evidences of the
similarity of the species. The dogs used by our northern Indians
resemble very much, in their general appearance, the wolves of that
region, and do not seem very far removed from that race of animals,
notwithstanding they have been in a state of captivity, or
domestication, beyond the traditionary chronicles of this rude people.

Another strong circumstance in favour of the common origin of these two
quadrupeds, is the existence in our own country of the Canis Latrans, or
prairie wolf, who whines and barks in a manner so similar to the smaller
varieties of dogs, that it is almost impossible to distinguish his notes
