OF THE DENARIVS.
AS I have made for measures the Ro∣mane foot, the foundation of my inquiry, and therefore have hand∣led it in the precedent Treatise: so for finding out of weights, I shal take the denarius as an undeniable principle, from whence those of the ancients by a necessa∣ry consequence may be inferred.
