Holograph account of errors in the Exchequer and Mint weights of 1588 and 1707 and the unused Scottish weights of 1607
The two standard Piles of English Troy Weights kept in the{illeg} Excheqr & Mint were both made in the year 1588, & are of the same weight, excepting that the Mint Pile is about a grain heavier then the Excheqr Pile. The Scotch Pile makde in ye year 1607 has been kept without wearing & is lighter then the English Pile by 9oz. 6dwt. 16gr, as it ought to be.✝ The new Pile made 1707 & stamped wth the rose & thistle crowned is about 3 grains heavier then ye excheqr Pile & 3gr heavier then the Old Mint Pile. In In Thise newMint Piles the small weights are in exact proportion wth the great ones. + The old Mint Pile oughtis to be kept used kept as a standard only to try the new +& the new used as a standard to mak ty the Bell weights.
+ In the Exchequer Pile the outmost weight is too light by 12 grains the outweight but one t{illeg}oo heaving by 9 grains
+ The outmost weight of the Exchequer Pile is 12 grains lighter then the outmost weight of the mint Piles & the outmost weight but one of ye Excheqr Pile is 9 grains heavier thaen then the outmost weight but one of the Mint Pile. The ounce weight & half ounce weight of the Excheqr Pile are each of them grain lighter then ye like Mint weight. {illeg} The rest of ye Excheqr weights equal the correspondent Mint weights wthout any sensible difference. {illeg} Where the weights differ The errors isare in ye Exchequer weights. For the {illeg} greater & smaller mint weights are in proportion to the samller, {illeg} in the Mint Pile, but not in the Excheqr Pile. For in the Excheqr {illeg}Pile the outward weight is a penny weight lighter then then ye rest remainder of the weights within it, & the outward weight of this remainder is 9gr heavier them all remainder {illeg}of the weights within it. But in ye Mint Pile the outward weight equals the summ of the inward weights in the ends within a grain or 2 The new Pile made this year 1707 & stamped wth the rose & thistle crowned is about 3gr heavier then the Excheqr Pile & 3gr & heavier then the Old Mint Pile. In the Mint Piles the small weights are in Proportion to the great {illeg} This old Mint Pile is now to be kept as a standard only to try the new Mint Pile & the new {illeg} is to be used as a standard to try the Bell weights. The weights in the new Mint Pile are in exact proportion to one another.
