Spirit
This name is usually given to fluids obtained by distillation, and that are lighter specifically than water. Essential oil of turpentine is called spirit of turpentine; and the spirits of peppermint, aniseed, etc., are thus denominated because their essential oils have been dissolved in alcohol. Hydrochloric acid is frequently called spirit of salts. In its strictest sense, however, alcohol is meant when the term spirit is employed. See ALCOHOL; DISTILLATION.
