MEDICINAL DYNAMETER AND SCALE OF EQUIVALENTS . Engraved for the Second American Edition of Paris’s Pharmacologia. EXPLANATION. This Instrument will shew on bare inspection, the quantity of active matter contained in any given weight or measure (according as it is solid or liquid) of any Officinal 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, placed in coloured squares; and each Officinal Preparation is marked by a line corresponding in colour with that of its active ingredient. If we require the quantity of active matter in any given dose of an Officinal 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.
