COCK'S-COMB, in botany, a cultivated form of _Celosia cristata_ (natural
order Amarantaceae), in which the inflorescence is monstrous, forming a
flat "fasciated" axis bearing numerous small flowers. The plant is a
low-growing herbaceous annual, bearing a large, comb-like, dark red,
scarlet or purplish mass of flowers. Seeds are sown in March or April in
pans of rich, well-drained sandy soil, which are placed in a hot-bed at
65 deg. to 70 deg. in a moist atmosphere. The seedlings require plenty
of light, and when large enough to handle are potted off and placed
close to the glass in a frame under similar conditions. When the heads
show they are shifted into 5-in. pots, which are plunged to their rims
in ashes or coco-nut fibre refuse, in a hot-bed, as before, close to the
glass; they are sparingly watered and more air admitted. The soil
recommended is a half-rich sandy loam and half-rotten cow and stable
manure mixed with a dash of silver sand. The other species of _Celosia_
cultivated are _C. pyramidalis_, with a pyramidal inflorescence, varying
in colour in the great number of varieties, and _C. argentea_, with a
dense white inflorescence. They require a similar cultural treatment to
that given for _C. cristata_.

COCKTON, HENRY (1807-1853), English humorous novelist, was born in
London on the 7th of December 1807. He published a number of volumes,
but is best known as the author of _Valentine Vox, the Ventriloquist_
(1840) and _Sylvester Sound, the Somnambulist_ (1844). He died at Bury
St Edmunds on the 26th of June 1853.

COCKX (or COCK), HIERONYMUS [JEROME] (1510-1570), Flemish painter and
engraver, was born at Antwerp, and in 1545 was admitted to the Gild of
St Luke as a painter. It is as an engraver, however, that he is famous,
a number of portraits and subject-pictures by him, and reproductions of
Flemish masters, being well known. His brother Matthys (1505-1552) was
also a painter.
