Elixir of phosphorus, 8 fluidounces.

Each fluidrachm (teaspoonful) of the finished elixir contains one-half grain of quinine, one-hundredth of a grain of strychnine, and the two-hundredth part of a grain of phosphorus. This formula in substance was presented at the meeting of the Pennsylvania Pharmaceutical Association, 1881.
