GUMS, RESINS, AND KINOS. 241 
in the scaly porous bark of this tree, but one frequently comes 
upon quite a store of the substance through tapping the com: 
munication with a reservoir underneath the bark, or between the 
concentric circles of wood. Frequently, on felling a tree, large 
masses of indurated kino (always more or less admixed with woody 
matter) may be obtained in cavities around these circles, and the 
presence of gum-veins of greater or less extent is always notice- 
able in a log of this timber. This interior kino, although quite 
bright when first deposited, has frequently the appearance of a 
very pulverulent purplish-red hematite, such, for instance, as is 
common in the Elba mines. It readily makes an impalpable 
powder of a Venetian red colour, soiling everything with which it 
comes into contact. Such kino is very variously soluble in water, 
whereas the freshly exuded pure substance, which is almost of a 
vermilion colour frequently, and, therefore, the most brilliantly 
tinted of all kinos, is readily and completely soluble in cold water. 
It forms part of the ‘‘ Botany Bay kino’’ of commerce, and 
Dr. Bancroft, of Brisbane, says that it may be administered 
medicinally in doses of from two to ten grains.

“Mountain Bloodwood.” (For other names, see ‘‘ Timbers.’’) 
This ‘‘ Bloodwood” yields far less kino than £. coryméosa, 
and the product is by no means of such a brilliant colour, having 
a liver-coloured cast, but redder than that of Z. punctata. It is 
very friable, yielding a powder of a very dark buff colour.

This well-known tree is by no means an abundant yielder 
of kino. A sample sent to Dr. Wiesner, of Vienna, some time 
ago, is thus described by him :—‘ Readily soluble in water; solu- 
tion pale reddish-yellow, slightly acid, very turbid on cooling ;
