BRAN, the outer skins or husks of ground wheat, rye, or other farinaceous grain, separated by the boulder from the flour. Wheat bran is employed in the manufacture of starch, and by dyers in making the "sour water" used in preparing the dyes. By the process of boiling in bran-water, calico-printers remove colour from those parts of maddered goods which are not mordanted. Some valuable observations on this subject will be found in the ninth
number of the Bulletin de la Société Industrielle de Mulhausen. See DYING.
