The U. S. P. IX process is an improvement over all preceding formulas as the flavor is derived from the tincture of fresh orange peel and the alkaline magnesium carbonate of the U. S. P. VIII, which modified the flavor, has been replaced by inert talc, the latter being used as a distributing and filtering medium. The British preparation, which is a mere mixture of the tincture with syrup, is inferior. The syrup has an agreeable, slightly acid flavor, for which it is alone employed. For a process by E. E. Williams, using powdered pumice to disintegrate the orange peel, see D. C., 1898, 125.
