EXAMPLE
“… Which computation is sufficiently justified by the Customs of the Three Kingdoms, whose intrinsick value are thought to be near a Million per annum, viz. Six hundred thousand pounds, payable to the King; 100 thousand Pounds, for the charges of Collecting, &c. Two hundred thousand pounds smuckled by the Merchants, and one Hundred thousand pounds gained by the Farmers; according to common Opinion, and Mens Sayings: And this agrees also with that proportion, or part of the whole Trade of the World, which I have estimated the Subjects of the King of England to be possessed of; viz, of about Ten of Forty Five Millions. …”
