Pigment Says The Chemical News Supplies A Desideratum Hitherto In

vain sought for by artists. It is the nearest approach to a perfect

yellow in existence, and more closely resembles the purity of the

prismatic spectrum than any other artificial colour. It is transparent,

has great brilliancy and richness, both pure and in combination, and is

very permanent, being entirely unaffected by exposure to sulphuretted

hydrogen and other atmospheric impurities, or to the direct rays of the

sun during an entire summer. Aureolin, with ultramarine and madder red,

completes the triad of brilliant, permanent, and transparent primitive

colours." The above only tallies with the statements of several

scientific chemists and artists of note, statements which a prolonged

personal experience of the colour enables us to endorse. To our

knowledge, aureolin is quite uninjured by the severest tests to which a

pigment can be subjected. We have found it bear with impunity, even in

its lightest and faintest tints, the foulest gas and the brightest

sunshine. Damp has no effect upon it; and in oil, water, or fresco, it

is equally eligible. With all other colours aureolin mixes safely and

readily, forming combinations of the utmost variety and value. It

affords beautiful transparent tints, well defined, and of exceeding

purity; the paler washes being at once clear and delicate, and admitting

the most subtle gradations of tone. The artistic properties of

aureolin, however, will be best described by quoting the following
