RM2CE293X–. The elements of materia medica and therapeutics (Volume 2) . Description.—The grains (semina hordei cruda) are too well known to needdescription. Deprived of their husk by a mill, they form Scotch, hulled, or potbarley (hordeum mundatum). When all the integuments of the grains areremoved, and the seeds are rounded and polished, they constitute pearl barley(hordeum perlatum). The farina obtained by grinding pearl barley to powderis called patent barley. Composition.—According to Einhof (Gmelins Handb. ii. 1344.) 100 partsof ripe barley-corns consist of husk 18-75, meal 70*05, water 11-20. The
