and descriptions of the apparatus used are known, but no allusion to the distillation of wine occurs in any existing reference to the chemistry of that period. Rhazes, who died in A.D. 925, is alleged to have mentioned a spirit distilled from wine, but Berthelot shows that this is a misunderstanding of a passage relating to false or artificial wines.
Water distilled from roses is mentioned by Nicander, about 140 B.C., and the same author employs the term ambix for the pot or apparatus from which this water was obtained. The Arabs adopted this word, and prefixing to it their article, al, made it into alembic. This in English appeared for some centuries in the abbreviated form of limbeck.

Pissaeleum was a peculiar form of distillation practised by the Romans. It was an oil of pitch made by hanging a fleece of wool over a vessel in which pitch was being boiled. The vapour which collected was pressed out and used.
Distilled waters from roses and aromatic herbs figured prominently in the pharmacy of the Arabs, and Geber, perhaps in the eighth century, describes the process, and may have used it for other than pharmaceutical purposes. Avicenna likens the body of man to a still, the stomach being the kettle, the head the cap, and the nostrils the cooling tube from which the distillate drips.
M. Berthelot gives the following from the Book of Fires of Marcus Grecas, which he says could not be earlier than 1300, as the first definite indication of a method of producing what was called aqua ardens. "Take a black wine, thick and old. To 1/4 lb. of this add
