A LETTER ON MR. McCULLA'S
By which computation, two shillings of his notes, which he sells for one pound weight, will weigh | 6288 | grains. | |
But one pound avoirdupois weighs, as above | 6960 | grains. |
This difference makes 10 per cent to Mr. McCulla's profit, in point of weight.
The old Patrick and David halfpenny weighs | 149 | grains. | |
Mr. McCulla's halfpenny weighs | 131 | grains. | |
The difference is | 18 |
Which is equal to 10½ per cent.
The English halfpenny of king Charles II weighs | 167 | grains. | ||
McCulla's halfpenny weighs | 131 | grains. | ||
The difference | 36 |
Which difference allowed, a fifth part is 20 per cent.
ANOTHER COMPUTATION.
Mr. McCulla allows his pound of copper (coinage included) to be worth twentypence; for which he demands two shillings.
His coinage he computes at sixpence per pound weight; therefore, laying out only twentypence, and gaining fourpence, he makes per cent profit | 20 | |
The sixpence per pound weight, allowed for coinage, makes per cent | 30 | |
The want of weight in his halfpenny, compared as above, is per cent | 10 | |
By all which (viz. coinage, profit, and want of weight) the publick loses per cent | 60 |
