The percolate is evaporated to dryness at a temperature not exceeding 60°C—the residue is treated with a sufficiency of N/10, H,S04 and I120. The alkaloidal solution is treated with NH3 and E. in repeated quantities. The E washings are evaporated and dissolved in a measured volume of N/10, H2S04, which is then back-titrated with N7.-,o KOH, using htcmatoxylin as indicator. The factor 0'064 is given for determining the amount of aconitine present. Adeps Lanae. M.P. 40°C. Ash limit O'3 per cent. M.P. 40 to 44 4° No free fatty acids, alkalies, chlorides, or organic C.
