Citrate of lithium, 640 grains.

Simple elixir, 16 fluidounces

Dissolve the citrate of lithium in the simple elixir, and filter if necessary.

Each fluidrachm (teaspoonful) of the finished elixir contains five grains of citrate of lithium. This proportion was adopted by the joint committee of the National College of Pharmacy and the Medical Society of the District of Columbia.

In former editions of our formula we used two hundred and fifty-six grains of citrate of lithium, but the National Formulary established the proportions of six hundred and forty grains, which we adopt.
