Elixir of pyrophosphate of iron with quinine and cinchonine, 16 fluidounces.
Strychnine, 1 1/4 grains.
Acetic acid, a sufficient quantity.
Triturate the strychnine in a mortar with enough acetic acid to effect its solution, then mix this with the elixir.
Each fluidrachm (teaspoonful) of the finished elixir contains two grains of pyrophosphate of iron, and the equivalent of one-half grain of quinine and one-fourth grain of cinchonine as the acetates of these alkaloids, and one-hundredth of a grain of acetate of strychnine.
