Which is 4li 0s 5d per cwt standard weight, besides the interest of about 200000li which is equipollent to 7s 6d per cwt.

Whereas 3li 16s per cwt avoirdepois, is but 4li 1s 5d per cwt standard.

So her Majesty loses 6s 6d per cwt standard weight which in seven years amounts to 72000, besides the loss by the fall of the price in the end of the contract

If the Coinage Duty & Post Groats had not been remitted, & her Majesty had paid only 3li 8s 6d per cwt standard weight, the contract would have been nearly equal, except the loss by the fall of the price in the end of it.

This loss, if the contract should cease at Christmas come twelve month might amount to 50 or 60 thousand pounds & so is equipollent to about 5s per cwt standard weight in the price.

And one hundred Tunns added to the annual purchased, is equipollent to 2s added to the price
