Most, if not all, the usual black colours have iron for a basis, the black oxide of which is developed by galls, logwood, or other substances containing gallic acid.

So like, egad, we're just the same; I never half squeeze out a thought, But jumps its fellow on the spot My tenderest dreams, my fondest touch, Are victims to his ready clutch; The whirling waltz, the gay costume, The porcelain tooth, the gallic bloom; The vapid smiles, the lisping loves Of turtles (never meant for doves)

I allude to art favourable to the Commune, and not that coëval with it, or the vast mass of pictorial unpleasantly born of gallic rage during the Franco-Prussian war, including such designs as the horrible allegory of Bayard, "Sedan, 1870," a large work depicting Napoleon III.
