The Computation that he talks of, is that which sets theDenarius as 62 | Grains Tray, and the Penny at 8 Grains;which latter is undoubtedly false, as I shall shew, afterhaving given the Pounds, Ounces, and Denarii mention’d inthese Papers at one View.

I wonder the DoBor did not stick to this Pound, which isa whole Number, especially, since the Ounce of it is nearthe Avoirdupois Ounce, which he takes to be the Roman .

The Difference between his Pound of 5245.752, &fc.mine 5208 is 57.752, &c. Grains Troy , which is little morethan ~ of a Pound Troy ; consequently in a little more than152 Pounds Weight, his would exceed mine by a PoundTroy. I think 1 have proved mine to be the true RomanPound ; and if I have, it is plain that his is too heavy. Itis plain also from what went before, that his Over-weight waschiefly owing to his following Mr. Greaves in his Notion,that the Roman Ounce and Avoirdupois Ounce are thefame.

I shall now give an Account os the Roman Weights accord-ing to my Computation, and then shall proceed to the Con-sideration of his second general Mistake, which has spoiledhis Tables of Money, as the first did those of Weight.
