ternal orifices of the nostrils are upraised and assume a
crescentic outline.

I must still say a few words on some of the foreign Crested breeds. The
skull of a crested, rumpless, white Turkish fowl is very slightly
protuberant, and but little perforated; the ascending branches of the
premaxillary {265} are well developed. In another Turkish breed, called
Ghoondooks, the skull is considerably protuberant and perforated; the
ascending branches of the premaxillary are so much aborted that they
project only 1/15th of an inch; and the inner processes of the nasal
bone are so completely aborted, that the surface where they should have
projected is quite smooth. Here then we see these two bones modified to
an extreme degree. Of Sultans (another Turkish breed) I examined two
skulls; in that of the female the protuberance was much larger than in
the male. In both skulls the ascending branches of the premaxillary
were very short, and in both the basal portion of the inner processes
of the nasal bones were ossified together. These Sultan skulls differed
from those of English Polish fowls in the frontal bones, anteriorly to
the protuberance, not being broad.

The last skull which I need describe is a unique one, lent to me by Mr.
Tegetmeier: it resembles a Polish skull in most of its characters, but
has not the great frontal protuberance; it has, however, two rounded
knobs of a different nature, which stand more in front, above the
lachrymal bones. These curious knobs, into which the brain does not
enter, are separated from each other by a deep medial furrow; and this
is perforated by a few minute pores. The nasal bones stand rather wide
apart, with their inner processes, and the ascending branches of the
premaxillary, upturned and shortened. The two knobs no doubt supported
the two great horn-like projections of the comb.

From the foregoing facts we see in how astonishing a manner some of the
bones of the skull vary in Crested fowls. The protuberance may
certainly be called in one sense a monstrosity, as being wholly unlike
anything observed in nature: but as in ordinary cases it is not
injurious to the bird, and as it is strictly inherited, it can har
