Dr. Stenhouse, of Liverpool, once made a careful analysis of a sample package of black tea, which was found to contain "some pure Congo tea leaves, also siftings of Pekoe and inferior kinds, weighing together twenty-seven per cent of the whole. The remaining seventy-three per cent was composed of the following substances; Iron, plumbago, chalk, China-clay, sand, Prussian-blue, tumeric, indigo, starch, gypsum, catechu, gum, the leaves of the camelia, sarangna, Chlorantes officinalis, elm, oak, willow, poplar, elder, beach, hawthorn, and sloe."
MILK CREAM BUTTER
MILK.
hemically considered, the constituents of milk are nitrogenous matter (consisting of casein and a small proportion of albumen), fat, sugar of milk, mineral matter, and water, the last constituting from sixty-five to ninety per cent of the whole.
The proportion of these elements varies greatly in the milk of different animals of the same species and of the same animals at different times, so that it is not possible to give an exact analysis.
