According to the ancients, a thick, black, acrid humour, secreted, in the opinion of some, by the pancreas; in that of others, by the suprarenal capsules. Hippocrates, Galen, Aetius, and others, ascribe great influence to the Atrabilis in the production of hypochondriasis, melancholy, and mania. There is really no such humour. It was an imaginary creation.-Aretaeus, Rufus of Ephesus, &c.
