![•31 Jalap. To contain at least S per cent, alcohol-soluble resin and not more than T5 per cent, ether-soluble resin (was*12 per cent, alcohol soluble and 1'2 per cent, ether-soluble). Assay.—The drug in No. CO powder is percolated with E, and the percolate evaporated. This gives the percentage of ether-soluble resin. The marc is then again percolated with ale. and a volume of this percolate is shaken with an equal volume of chi. and of 1I20. The chi. solution is evaporated and weighed when of constant weight to obtain the percentage of resin insoluble in ether which added to the first figure gives total resin. Jur/lanx.—Omitted. Kaolinum. Native aluminium silicate eonsi.-ting of the pure silicate [Ho AL Si2 Os + H20] powdered and freed from gritty particles. Should leave not less than 85 per cent, non-volatile residue on igni- tion. Is tested for iron. Kamala.—Omitted. Krameria. Now Krameria triandra (Peruvian), K.
