Apothecary’s weights, by which all medicinal preparations ought to be weighed, are divided into pounds, ounces, scruples, drams, and grains.

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.

Domestic, or Approximate Measures. A tablespoon contains about four drams; a teaspoon, one dram; a dessertspoon, three drams; a wineglass, tvre ounces. 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.
