Hypophosphite of calcium, 128 grains.
Hypophosphite of sodium, 128 grains.
Citric acid, 30 grains.

The citric acid and hypophosphites are to be dissolved in the water, and the solution mixed with enough elixir of cinchona to make sixteen fluidounces, and then filtered. Each fluidrachm contains one grain each of the hypophosphites of calcium and sodium. This formula is identical in strength with that of the National Formulary.
