Elixir of beef, 16 fluidounces.

Water, 1/2 fluidounces.

Citrate of iron and ammonium, .128 grains.

Dissolve the citrate of iron in the water, add the elixir of beef, and filter if necessary.

Each fluidrachm (teaspoonful) of the finished elixir contains two grains of extract of beef and one grain of citrate of iron.

This preparation is far from permanent. It deposits a precipitate by age, which evidently results from the reaction between the chloride of sodium, present in large amount in the beef extract, and the citrate of iron. The substitution; of chloride of iron for the citrate might prove advantageous. but the demand is for an elixir of beef with citrate of iron.
