e well developed. Skull with deep medial
furrow; occipital foramen, sub-triangular, vertically elongated. Voice
peculiar. Eggs rough, buff-coloured. Disposition extremely quiet. Of
Chinese origin.

4. DORKING BREED.--Size great; body square, compact; feet with an
additional toe; comb well developed, but varies much in form; wattles
well developed; colour of plumage various. Skull remarkably broad
between the orbits. Of English origin.

The white Dorking may be considered as a distinct sub-breed, being a
less massive bird.

5. SPANISH BREED.--Tall, with stately carriage; tarsi long; comb
single, deeply serrated, of immense size; wattles largely developed;
the large ear-lobes and sides of face white. Plumage black glossed with
green. Do not incubate. Tender in constitution, the comb being often
injured by frost. Eggs white, smooth, of large size. Chickens feather
late, but the young cocks show their masculine characters, and crow at
an early age. Of Mediterranean origin.

The _Andalusians_ may be ranked as a sub-breed: they are of a slaty
blue colour, and their chickens are well feathered. A smaller,
short-legged Dutch sub-breed has been described by some authors as
distinct.

6. HAMBURGH BREED (fig. 31).--Size moderate; comb flat, produced
backwards, covered with numerous small points; wattle of moderate
dimensions; ear-lobe white; legs blueish, thin. Do not incubate. Skull,
with the tips of the ascending branches of the premaxillary and with
the nasal bones standing a little separate from each other; anterior
margin of the frontal bones less depressed than usual.

There are two sub-breeds; the _spangled_ Hamburgh, of English origin,
with the tips of the feathers marked with a dark spot; and the
_pencilled_ Hamburgh, of Dutch origin, with dark transverse lines
across each feather, and with the body rather smaller. Both these
sub-breeds include gold and silver varieties, as well as some other
sub-varieties. Black Hamburghs have been produced by a cross with the
Spanish breed.

7. CRESTED OR POLISH BREED (fig. 32).--Head with a large, rounded crest
of feathers, supported on a hemispherical protuberance of the frontal
bones, {228} which includes the anterior part of the brain. The
ascending branches of the premaxillary bones and the inner nasal
processes are much sho
