dog and female wolf
afforded animals much more dog-like in aspect--slouched ears and even
pied in color. If you look at the descriptions and illustrations of
these two hybrids, you will perceive at a glance that the doubt arises
to the mind in the case of the first, 'what genus of _wolf_ is this?'
whereas in the case of the second, 'what a curious _mongrel dog_!'
The views of Mr. Walker in his work on Intermarriage, before alluded
to, agree substantially with those of Mr. Orton, _so far as regards
crossing between different breeds_; but they cover a broader field of
observation and in some respects differ. Mr. Walker maintains that
when both parents are of the _same breed_ that _either parent may
transmit either half_ of the organization. That when they are of
_different varieties_ or breeds (and by parity of reasoning the same
should hold, strongly, when hybrids are produced by crossing different
_species_) and supposing also that both parents are of equal age and
vigor, that the _male_ gives the _back head and locomotive organs_ and
the _female_ the _face and_ nutritive organs--I quote his language:
"when both parents are of the same variety, _one parent communicates
the anterior part of the head, the bony part of the face, the forms of
the organs of sense_ (the external ear, under lip, lower part of the
nose and eye brows being often modified) _and the whole of the
internal nutritive system_, (the contents of the trunk or the thoracic
and abdominal viscera, and consequently the form of the trunk itself
in so far as that depends on its contents.)
The resemblance to that parent is consequently found in the forehead
and bony parts of the face, as the orbits, cheek bones, jaws, chin and
teeth, as well as the shape of the organs of sense and the tone of the
voice.
_The other parent communicates the posterior part of the head, the
cerebel situated within the skull immediately above its junction with
the back of the neck, and the whole of the locomotive system_; (the
bones, ligaments and muscles or fleshy parts.)
The resemblance to that parent is consequently found in the back head,
the few more movable parts of the face, as the external ear, under
lip, lower part of the nose, eyebrows, and the external forms of the
body, in so far as they depend on the muscles as well as the form of
the limbs, even to the fingers, toes and nails. * *
It is a fact established by my observations that in animals of the
