green, of a fine deep olive colour and sober richness. Advisedly or not,

it is used in landscape, sketching, &c.; but only in water, olive lake

supplying its place in oil. Like many other compound pigments, it is

either permanent, semi-stable, or fugitive, according to the

constituents of which it is composed. Generally speaking, it is more

beautiful than durable, and is often decidedly fugacious, fading on

exposure. I
is impossible for a writer to pronounce an absolute opinion

on the stability of all mixtures sold in a separate form, inasmuch as

the compounds of one firm may differ from those of another. We have

before expressed our dislike to such pigments, and this uncertainty with

regard to their composition serves to strengthen it. Nevertheless, as

there are exceptions to every rule, it must be admitted that the palette

possesses compounds always to be relied upon.

is in commerce exclusively an oil colour. When true, it is a lake

prepared from the green ebony, or laburnum, and is of considerable

permanence, transparency, and depth, both in water and oil; in which

latter vehicle it dries well. This variety, however, may be said to be

obsolete; having given way to a mixture, usually semi-stable, and liable

to blacken.
