Mono-bromated camphor, 128 grains.

Simple elixir, 15 fluidounces.

Alcohol, 1 fluidounces.

Dissolve the mono-bromated camphor in the alcohol, and stir this solution slowly in the simple elixir.

Each fluidrachm (teaspoonful) of the finished elixir contains one grain of mono-bromated camphor. Mr. T. Mundy, of Paris, has recommended an elixir of mono-bromated camphor containing nine grains in fifteen fluidrachms, but the amount of alcohol is very great. However, as alcohol is the best common solvent for this substance, we prefer a simple alcoholic solution to an elixir, as the water present in the elixir favors precipitation.
