BARK OF OAK

for tanning. Unfortunately, the Tables of Revenue published by the Board of Trade, mix up this bark and the dyeing barks together, and give the sum of the whole for 1835, at 826,566 cwts., of which only 2,264 were re-exported. The duty is 1 d. per cwt. from British po e ions, and 8 d. from other parts. BARLEY ( Orge , Fr. Gerste , Germ.) English barley is that with two-rowed ears, or the hordeum vulgare distich on of the botanists; the Scotch beer or bigg, is the hordeum vulgare hexastichon . The latter has two rows of ears, but 3 corns come from the same point, so that it seems to be six-eared. The grains of bigg are smaller than those of barley, and the husks thinner. The specific gravity of English barley varies from 1·25 to 1·33; of bigg from 1·227 to 1·265; the weight of the husk of barley is 1 ⁄ 6 , that of bigg 2 ⁄ 9 . 1000 parts of barley flour contain, according to Einhof, 720 of starch, 56 sugar, 50 mucilage, 36·6 gluten, 12·3 vegetable albumen, 100 water, 2·5 phosphate of lime, 68 fibrous or ligneous matter. Sp. gravity of barley, is 1·235 by my trials.
