Elixir of valerianate of ammonium with quinine and pyrophosphate of iron, 8 fluidounces.
Elixir of valerianate of ammonium with cinchonidine and pyrophosphate of iron, 8 fluidounces.
Strychnine, 1 1/4 grains.
Triturate the strychnine in a mortar with acetic acid in sufficient quantity to effect its solution, and add this to the elixirs, having previously mixed them together; and filter if necessary.
Each fluidrachm (teaspoonful) of the finished elixir contains two grains of valerianate of ammonium, one-fourth grain of cincho-nidine, one-eighth grain of quinine, one grain of pyrophosphate of iron, and one-hundredth grain of strychnine. The alkaloids exist as acetates. This elixir should be as nearly neutral as it is possible to make it.
