It is customary to distinguish quantities of fluid from dry substances, by prefixing the letter f. (fluid) when an ounce or dram is mentioned in medical works, as may be seen in the first of these tables.
The following table of the gradations of doses of medicines for different ages, will in general be found pretty correct, and ought never to be deviated from, except by professional advice.
If at the age of maturity the dose be one dram, the proportion will be at
| From | 14 | to 21 years, | 2 scruples, |
| 7 | 14 | half a dram, | |
| 4 | 7 | 1 scruple, | |
