same length. (See Sir Everard Home on Comparative Anatomy.)--L.] There
is one circumstance, however, which seems to mark a decided difference
between the two animals; the eye of the dog of every country and species
has a circular pupil, but the position or form of the pupil is oblique
in the wolf. Professor Bell gives an ingenious but not admissible reason
for this. He attributes the forward direction of the eyes in the dog to
the constant habit, "for many successive generations, of looking towards
their master, and obeying his voice:" but no habit of this kind could by
possibility produce any such effect. It should also be remembered that,
in every part of the globe in which the wolf is found this form of the
pupil, and a peculiar setting on of the curve of the tail, and a
singularity in the voice, cannot fail of being observed; to which may be
added, that the dog exists in every latitude and in every climate, while
the habitation of the wolf is confined to certain parts of the globe.

There is also a marked difference in the temper and habits of the two.
The dog is, generally speaking, easily manageable, but nothing will, in
the majority of cases, render the wolf moderately tractable. There are,
however, exceptions to this. The author remembers a bitch wolf at the
Zoological Gardens that would always come to the front bars of her den
to be caressed as soon as any one that she knew approached. She had
puppies while there, and she brought her little ones in her mouth to be
noticed by the spectators; so eager, indeed, was she that they should
share with her in the notice of her friends, that she killed them all in
succession against the bars of her den as she brought them forcibly
forward to be fondled.

M.F. Cuvier gives an account of a young wolf who followed his master
everywhere, and showed a degree of affection and submission scarcely
inferior to the domesticated dog. His master being unavoidably absent,
