in 1850; 27,212 bags in 1851, and 19,946 bags in 1852; they
come from Calcutta and Bombay, and are also used for dyeing yellow and
black. The price in January, 1853, was 6s. to 12s. per cwt. The
average annual imports into the United Kingdom may be taken at 1,200
tons.
KINO.--The Kino, of Botany Bay and Van Diemen's Land, is the produce
of the iron bark tree, _Eucalyptus resinifera_. White ("Journal of a
Voyage to New South Wales"), says this tree sometimes yields, on
incision, 60 gallons of juice. Kino is imported in boxes. The
tincture of kino is used medicinally, but an inconvenience is
frequently found to arise, from its changing to the gelatinous form.
Dr. Pereira seems to think this species of kino consists principally
of pectin and tannic acid. That chiefly used as East Indian kino, is
an extract formed by inspissating a decoction of the branches and
twigs of the gambler plant. Vauquelin analysed it, and found it to
consist of, tannin and peculiar extractive matter, 75; red gum, 24;
insoluble matter, 1.
The East Indian kino, imported from Bombay and Tellicherry, is the
produce of _Pterocarpus marsupium_, a lofty, broad-spreading forest
tree, which blossoms in October and November. The bark is of a greyish
color, and is upwards of half an inch in thickness on the trunk. When
cut, a blood-red juice speedily exudes and trickles down; it soon
thickens, and becomes hard in the course of fifteen or sixteen hours.
The gum is extracted in the season when the tree is in blossom, by
making longitudinal incisions in the bark round the trunk, so as to
let the gum ooze down a broad leaf, placed as a spout, into a
receiver. When the receiver is filled it is removed. The gum is dried
in the sun until it crumbles, and then filled in wooden boxes for
exportation.
_P. erinaceus_, a tree 40 to 50 feet in height, a native of the woods
of the Gambia and Senegal, furnishes kino, but none is collected in or
exported from Africa. _Butea frondosa_, or the dhak tree of the East
Indies, furnishes a similar product, in the shape of a milky, colored,
brittle, and very astringent gum. Kino is used as a powerful
astringent, and is administered in the form of powder and tincture.
Some specimens of Butea kino, analysed by Prof. Solly, after the
impurities had been separated, yielded 731/4 per cent. of tannin.
VALONIA is the commercial name of the cupula or cup of the acorn,
produced by the _Quercus aegilops_ and its varieties, the Balon
