he was sent to the menagerie, where he pined for his loss, and would
scarcely take any food for a considerable time. At length, however, he
attached himself to his keepers, and appeared to have forgotten his
former associate. At the expiration of eighteen months his master
returned, and, the moment his voice was heard, the wolf recognised him,
and lavished on his old friend the most affectionate caresses. A second
separation followed, which lasted three years, and again the
long-remembered voice was recognised, and replied to with impatient
cries; after which, rushing on his master, he licked his face with every
mark of joy, menacing his keepers, towards whom he had just before been
exhibiting fondness. A third separation occurred, and he became gloomy
and melancholy. He suffered the caresses of none but his keepers, and
towards them he often manifested the original ferocity of his species.

These stories, however, go only a little way to prove that the dog and
the wolf have one common origin. [There are some naturalists that even
go so far as to state that the different varieties of dogs are sprung
from, or compounded of, various animals, as the hyaena, jackal, wolf,
and fox. The philosophic John Hunter commenced a series of experiments
upon this interesting subject, and was forced to acknowledge that "the
dog may be the wolf tamed, and the jackal may probably be the dog

The ancient Cynegetical writers were not only acquainted with the cross
between the wolf and dog, but also boasted the possession of breeds of
animals, supposed to have been derived from a connection with the lion
and tiger. The Hyrcanian dog, although savage and powerful beast, was
rendered much more formidable in battle, or in conflict with other
animals, by his fabled cross with the tiger. In corroboration of this
singular, but not less fabulous belief, Pliny states that the
