ON THE BREEDS OF THE DOMESTIC PIGEON.

Believing that it is always best to study some special group, I have,
after deliberation, taken up domestic pigeons. I have kept every breed
which I could purchase or obtain, and have been most kindly favoured
with skins from several quarters of the world, more especially by the
Honourable W. Elliot from India, and by the Honourable C. Murray from
Persia. Many treatises in different languages have been published on
pigeons, and some of them are very important, as being of considerable
antiquity. I have associated with several eminent fanciers, and have
been permitted to join two of the London Pigeon Clubs. The diversity
of the breeds is something astonishing. Compare the English carrier
and the short-faced tumbler, and see the wonderful difference in their
beaks, entailing corresponding differences in their skulls. The
carrier, more especially the male bird, is also remarkable from the
wonderful development of the carunculated skin about the head, and
this is accompanied by greatly elongated eyelids, very large external
orifices to the nostrils, and a wide gape of mouth. The short-faced
tumbler has a beak in outline almost like that of a finch; and the
common tumbler has the singular and strictly inherited habit of flying
at a great height in a compact flock, and tumbling in the air head
over heels. The runt is a bird of great size, with long, massive beak
and large feet; some of the sub-breeds of runts have very long necks,
others very long wings and tails, others singularly short tails. The
barb is allied to the carrier, but, instead of a very long beak, has a
very short and very broad one. The pouter has a much elongated body,
wings, and legs; and its enormously developed crop, which it glories
in inflating, may well excite astonishment and even laughter. The
turbit has a very short and conical beak, with a line of reversed
