BABLAH. The rind or shell which surrounds the fruit of the mimosa cineraria; it comes from the East Indies, as also from Senegal, under the name of Neb-neb. It contains gallic acid, tannin, a red colouring amtter, and an azotized substance; but the proportion of tannin is smaller than in sumach, galls, and knoppern (gall-nuts of the common oak) in reference to that of gallic acid, which is considerable in the bablah. It has been used, in dyeing cotton, for producing carious shades of drab; as a substitute for the more expensive astringent dye-stuffs.

BARBERRY. The root of this plant contains a yellow colouring matter, which is soluble in water and alcohol, and is rendered brown by alkalis. The solutions is employed in the manufacture of Morocco leather.

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 ewts., of which only 2,264 were re-exported- The duty is 1d. per ewt. from British possessions, and 8d from other barts.
