I have here gone no higher than the sextarius, as that is the greatest measure mentioned by Celsus; it has its name from making the sixth part of the Roman congius. I would have taken the table of weights from Dr Arbuthnot also, if he had given one accommodated to Celsus; but as he has not, I have composed the following, No. VI. according to the division of Celsus himself, who tells us[U], that he divides the _uncia_, or _ounce_, into _seven denarii_, and the _denarius_ into _six sextantes_. [U] Lib. v. cap. 17. Besides these, in several compositions our author uses _semuncia_ and _sescuncia_, that is _half an ounce_ and _ounce and half_; and to save the reader the trouble of reduction, I have given them also a place in the table. The accurate Mr Greaves[V], from repeated experiments, concluded the _Roman denarius_ to contain 62 grains English Troy weight, from which the proportions of the other weights are determined.
