    I Drachm (or flaidrachm) is equal to 4 Grams (or Flui- grams). I Ounce (or fluidounce) is equal to 30 Grams (or Flui- grams). I Gram (or Fluigram) is equal to 15 grains (or minims). 4 Grams (or Fluigrams) is equal to i drachm (or flui- drachm). ^ 30 Grams (or Fluigrams) is equal to i ounce (or fluid- ounce). Drops and Spoonfuls. 18. The average '* drop is equal to 0.05 fGm (or one- half fluidime), and i fluidime is about 2 drops. An average teaspoon holds 5 fGm; a dessertspoon, 10 fGm; a tablespoon, 20 fGm; and a wineglass, 75 fGm. Wherever 5 fGm is stated to be the dose of any preparation em- braced in this formulary, it is understood that a teaspoonful is meant, etc., and that the label should so indicate. This is done so as to show the relation of the dose to the total quantity prescribed. It will, how- ever, also serve to fix in our memory the fact that the average teaspoon holds more than one fluidrachm (4 fGm), and that it is safer and more correct to allow 5 fGm to the teaspoonful in making up the volume of a mixture. 19.
