Toe dram \ I three Icrupies. Thefcruple J I-twenty grains. The meafures likewife for liquids in this country are of different forts: with one fort beer being meafured, with the other wine. We employ the latter 5 ufing that meafure for a pint which is called a wine-pint. I'his pint we divide thus : The pint 1 . ffixteen ounces. } contams The ounce j [ eight drams. The gallon contains eight pints. As enly 437I grains : that is, lefs by 42|- grains ; fo that ten ounces Trqy are almoil equal to eleven Avoirdupois. NoWj as the compofitions of the Difpenfatory, and the ex- temporaneous prefcriptions of phyficians, are adapted to the Troy-weight, it is evident, that, if the ounce and half-ounce Avoirdupois are employed with the Troy dram and its fubdi- vifions, the ingredients muft be takeri in improper propor- tions. It is to be lamented that the Avoirdupois weights axe not banifhed entirely from the fhop? of apothecaries.
