Phosphate of iron, soluble (U. S. P.
1883), 256 grains.
Simple elixir, 12 fluidounces.
Distilled water, 4 fluidounces.
Dissolve the phosphate of iron in the distilled water and add the simple elixir.
Each fluidrachm (teaspoonful) of the finished elixir contains two grains of phosphate of iron.
In former editions of this work each fluidrachm represented one grain of phosphate of iron. The National Formulary has established two grains as the preferable amount, and in this edition we have accepted that quantity.
