27.9 Doses, Weights, etc.

Apothecary’s weights, by which all medicinal preparations ought to be weighed, are divided into pounds, ounces, scruples, drams, and grains. The characters marked on weights and graduated measures are explained as follows: Sj one ounce. f Ej one fluid ounce. gss half an ounce. 3i one dram. f3j one fluid dram. 3ss half a dram. Zo )j one scruple. Dss half a scruple. The grain weights are stamped with punch marks. 20 grains make one scruple. 60 drops make one fluid dram. 3 scruples make one dram. 8 drams make one fluid ounce. 8 drams make one ounce. 1 16 ounces make one pint. By apothecary's weight: lb The pound is equal to 12 ounces. The ounce is equal to 8 drams. By apothecary's measure: 3 The dram is equal to 3 scruples. D The scruple is equal to 20 grains. 0 The pint is equal to sixteen ounces. 3 The dram is equal to ninety drops, or sixty minims.

Spoons vary so much in size, that they should not be used as measures in giving powerful medicines. Spoons can also be used for measuring solid substances, but are not as accurate, as the solid substances vary very much in weight, in that I would not advise their use in measuring powerful drug. One dram, or 60 grains, to a teaspoonful. Four drams, or half an ounce, to a tablespoonful. The spoon should be level full for solids.
