Place the cassia fistula, tamarind, prune, and fig in a close vessel with five hundred cubic centimeters (500 Cc.) [16 fl℥, 435♏] of water, and digest for 3 hours by means of a water-bath. Separate the coarser portions with the hand, and rub the pulpy mass, first through a coarse hair sieve, and then through a fine one, or through a muslin cloth. Mix the residue with one hundred and fifty cubic centimeters (150 Cc.) [5 fl℥, 35♏] of water, and having digested the mixture for a short time, treat it as before, and add the product to the pulpy mass first obtained. Then, by means of a water-bath, dissolve the sugar in the pulpy liquid, and evaporate the whole, in a tared vessel, until it weighs eight hundred and ninety-five grammes (895 Gm.) [1 lb. av., 15 ozs., 250 grs.]. Lastly, add the senna and the oil of coriander, and incorporate them thoroughly with the other ingredients while they are yet warm"—(U. S. P.).
