This section is from the "Elixirs And Flavoring Extracts. Their History, Formulae, & Methods of Preparation" book, by John Uri Lloyd. Also available from Amazon: Elixirs and flavoring extracts,: Their history, formulae, and methods of preparation;
Valerianate of quinine, 128 grains.
Pyrophosphate of iron, 128 grains.
Strychnine, 1 1/4 grains.
Simple elixir, 16 fluidounces
Acetic acid, a sufficient quantity.
Triturate the strychnine in a mortar with acetic acid in amount sufficient to effect its solution, then add the valerianate of quinine and four fluidounces of simple elixir, and triturate until the valerianate is dissolved. Should the valerianate of quinine fail to dissolve after a moderate time, add a little acetic acid. Lastly, dissolve the pyrophosphate in the remainder of the simple elixir and mix the solutions.
Each fluidrachm (teaspoonful) of the finished elixir contains one grain each of the valerianate of quinine and pyrophosphate of iron, and one-fiftieth grain of strychnine.
This formula corresponds, regarding proportions, with one offered by the Druggists' Circular, 1871, excepting that ours contains half the amount of pyrophosphate of iron.
