Each fluid drachm contains 1 grain of phosphate of quinine and acid equal to about 10 minims of the dilute phosphoric acid.

This want of solubility is believed to be due to the length of time they have been kept before sale, as the best results have been obtained with the phosphate only a few days old.

In this formula avoirdupois weight and Imperial measure are adopted. 4633. Syrup of Phosphate of Manganese may be prepared in a similar man-

The same weight of quinia, prepared by precipitating an acidulated solution of the disulphate by solution of ammonia, collecting, washing, and drying at 100° Fahr., may be used, in the absence of the phosphate.
