by comparing the solid Inches in the Modius with thosein the Englijh Peck, between which there is but little Differ-ence. The solid Inches in the Modius are found by those in theCongius\ which, according to my Computation, are 205.5 789.For 8 Congii — 1644.6312 solid Inches make an Amphora.,

divided by 3, we shall have for the Modius 548.2104.

We have two different Estimates of the solid Inches andDecimals in the EngliJJj Peck.

The first is 544.5 ; this is the common Reckoning. Ifthis supposed Peck be taken from my Modius , it would leave

a Difference of 3.7104, and consequently the Modius would

be 1 -3.7104.

The second Estimate of th&EngliJJo Peck, which is the trueone, according to Ward' s Young Mat hem. Guide , p. 36, is

The Congius which the DoEtor makes Use os in order to

find his Modius , is 207.0676; which being multiplied by 8,

gives the Amphora 1656.5408. This being divided by 3,

gives the Modius 552.1802'.
