"Rectified Oil of Turpentine, fifteen mils [or 243 minims]; Expressed Oil of Almond, five mils [or 81 minims]; Syrup, twenty-five mils [or 406 minims]; Acacia, in fine powder, fifteen grammes [or 231 grains]; Water, a sufficient quantity, to make one hundred mils [or 3 fluid-ounces, 183 minims]. Introduce the acacia into a perfectly dry bottle of sufficient capacity, add the rectified oil of turpentine and the expressed oil of almond and shake the bottle thoroughly. Then add thirty mils [or 1 fluid-ounce, 7 minims] of "water and incorporate it by vigorous shaking. When the oil has been completely emulsified add first the syrup, in several portions, shaking after each addition, and then enough "water, in divided portions, shaking after each addition, to make the product measure one hundred mils [or 3 fluidounces, 183 minims]."

The U. S. P. VIII introduced this emulsion with the view of providing a simple and fairly permanent preparation. Rectified oil of turpentine should be used exclusively. The process is much like the one recommended by J. Winchell Forbes, and a mortar and pestle are not needed to produce a perfect emulsion.
Dose, one-half to one fluidrachm (1.9-3.75 mils).
