    [227° 7 has more affinity tothe Montpellier weight, being divided, : like that, into ounces, drachms, feruples, and grains. The Troy pound, indeed, contains only twelve ounces,, and the Montpellier fixteen ; but in the ounce there is on- ly a difference of feven grains and an half, the Zroy ounce being fo much heavier than the Montpellier. In the drachm the difference is lefs than a grain, in the*fcruple not a third of one. The grain differs more in propors! tion, as the Montpellier fcruple is divided into twenty- > four grains, and the Zrey fcruple into only twenty; but’ for the fatisfa€tion of thofe who may be curious to know: ~ the exact difference between rhe Englifh and Montpel-’ her weights, I have added a Table, in which is ex- prefied the value of the Montpéllier pound, half pound, - ounce, drachm, and grains, both in Yroy and Avoir-du-!
