Holograph notes on loss of weight of old hammered coin since the reign of Edward VI

In weighing some old hammered unclipt money, I found the crowns of King Edwd about 10 {illeg}or 11 gr too light, the $\frac{\mathrm{1}}{\mathrm{2}}$ crowns of K Iames & K. Charles I too light by 4 pr cent the hoarded shillings of Q. Eliz K Edward {illeg}by 7$\frac{\mathrm{1}}{\mathrm{4}}$ pr cent, the shillings of Q. Eliz by {illeg}10 pr cent, those of K Iames by 5$\frac{\mathrm{1}}{\mathrm{10}}$ pr cent, those of K. Char. I by 4$\frac{\mathrm{1}}{\mathrm{2}}$ pr cent. Half crowns of K. Char I by 4 pr cent. Whence these shillings weare 1 pr cent in about 15 years & half crowns 1 per cent in 19 or 20 years. And by consequence milled shillings weare 1 pr cent in about 24 years
