"This instrument will show on bare inspection the quantity of active matter contained in any given weight or measure (according as it is solid or liquid) of any Official compound, and the dose of any preparation which will be equivalent in strength to any given quantity of any other of the same class. The active principles, or Medicinal Bases, are distinguished by capital letters, place in colored squares; and each Official Preparation s given dose of an Official Preparation, we have only to bring such preparation to the number in question and the figure opposite the active ingredient answers the question, while those opposite to the other compounds of the same class denote the equivalent quantities. Unless otherwise expressed, the figures denote Grains for the solids, and Minim for the liquids."
