Weights and Measures in the Old Dispensatory.
TWenty Grains do make a Scruple. Three Scru∣ples make a drachm (commonly called a dram) Right Drachms make an Ounce. Twelve Ounces make a Pound.
As for the Colledges Measures I know not well what English Names to give them. 〈◊〉〈◊〉 holds in Syrups half an Ounce; in distilled Waters three Drachms. 〈◊〉〈◊〉 holds an ounce and an half. Hemina (which also they call Cotyla) contains nine Ounces. Libra holds twelve Ounces. A Sextary contains eighteen Ounces. A Congie six Sextaties.
These Measures amongst the Romans contained not just the same quantities; for their Cyathus contained an ounce and an half, a drachm and a scruple. Their Sextary contained but fourteen ounces, three 〈◊〉〈◊〉, and half a quarter; and among the Gracians not so much: It is called a 〈◊〉〈◊〉 because it is the sixt part of a Congie. Neither did the Roman Hemina contain altogether seven ounces and an half. Their Libra I suppose to be that which Galen calls 〈◊〉〈◊〉, viz. A Vessel to measure with; it was made of cleer Horn, and by certain lines drawn round it like rings, was divided into twelve equal parts, each part con∣taining an ounce.
