    acid in very feeble excess, and filter again. Distil oft' three fourths of the spirit, add to the residue the distilled water, evaporats at a gentle heat, but as rapidly as pos- sible, until the liquid is reduced to one third of its volume and no longer smells of alcohol; then let it cool. Add very cautiously, with constant stirring, a solution of the carbonate of potash so as nearly to neutralize the acid, care, however, being taken that an excess is not used. Set to rest for six hours, then filter, and add carbonate of potash in such quantity that the liquid shall acquire a decided allailine reaction. Place it in a bottle with the chloroform ; mix well by frequently repeated bi isk agita- tion, and pour the mixed liquids into a funnel furnished with a glass stop-cock. When the chloroform has sub- sided draw it oft' by the stop-cock, and distil it on a water- bath from a retort connected with a condenser. Dissolve the residue in warm rectified sjiirit; digest the solution with a little animal charcoal; filter, evaporate, and cool until colourless crystals are obtained. G. Atropinum. [M.
