sliced small, and macerated in enough cold water to cover them for 24 hours; the liquid is next pressed out, and after the fecula has subsided the clear portion is decanted, and heated to 180° or 190° Fahr., to coagulate the albumen; the liquid is then filtered while hot and evaporated by steam, or preferably by a current of warm air, until it is reduced to 221⁄2 lbs.; to this rectified spirit, 6 lbs., is added, and after thorough agitation the vessel is set aside for a week or a fortnight, after which the clear portion is gently poured from the sediment and preserved in well-closed bottles in a cool place. A very fine article. It represents an equal weight of the root.
