Mix the acetic acid with 100 (20 fluid ounces) of the alcohol, moisten the powder with 30 (6 fluid ounces) of the mixture, pack in a percolator, and percolate with the remainder of the menstruum. Continue the percolation with the alcohol until exhaustion is complete. Reserve the first 85 (17 fluid ounces) of percolate, concentrate the subsequent percolate to a soft extract, dissolve this in the reserved percolate, and add sufficient of the alcohol to make up to the required volume. Determine the proportion of alkaloids in the strong liquid extract, and adjust the finished product so that it shall contain alkaloids equivalent to 1 per cent. of alkaloidal hydrochlorides.
