We want enough pills to last ten days or thereabouts ; and the nightly allowance of each ingredient is about—apothecaries' system—two grains. A daily dose, then, of two pills, each containing one grain of the several constituents, will answer the purpose, and, plainly, twenty such half-strength pills will be needed. We must, then, order a mass composed of twenty grains each of the three constituents, and direct this to be divided into twenty pills. Metrically, we would rate the daily allowance of the several constituents at ten centigrammes, and the amount necessary for ten days would then be, of each, ten times ten centigrammes, or one gramme. The prescription would then read : Example IV.— For Miss M. N. [Apothecaries' System: 20 pills @ gr. j. of each ingredient.'] :^.
