Before I quit this Subject of the Liquid Measures, I can-not help taking Notice of a Fault in Dr. Arbuthnot, P. 124,in relation to the Cyathus-

Upon a Supposition .that Budæus s Emendation of a Pas-sage in Pliny is right, he fays, That the Cyathus of 0 simianWine came to two Nummi. It is strange, that he shouldsubstitute the Cyathus instead of the Uncia ; for the Unciaalone is mentioned by Pliny , and there is not a Word inthis Place relating to the Cyathus.

He could not have so far forgot himself, as not to knowthat the Cyathus and Uncia were two quite different Things;for the Cyathus was — Part of the Sextarius ; but as the Sex-tan ius contain’d 20 Ounces of Water or Wine, a singleOunce was only a ~ Part of it. Therefore the Cyathus wasto the Ounce as 20 to 12, or exactly as 1.666, &c. to 1,and consequently the Cyathus , exceeded the Ounce by aboveone Half. This being the Cafe, he must certainly have substi-tuted the Cyathus instead os the Uncia, in order to make hisComputation of Interest agree with what he imagined to bePliny s. The Place in Pliny is certainly a very difficult one,and was Hardouins Explanation of it right, the Ounce ofOsimian Wine was fold for 960 Sejlertii, or 8 Pounds ofour Money, according to my Value of a Sejlertius-, a Pricealtogether monstrous and incredible. Vide Plin. Edit.Hard - c Tom. i. p. 714.

By Budæus % Emendation of binis instead of vini, theOunce was fold for no more than 2 Sejlertii ; a wideDifference this in their Accounts! but I think neither ofthem right, nor indeed capable of being reconcil’d to Pliny.
