{illeg}|W|hich is 4li 0s 5d per C stan. weight, besides the interest of about 200000li wch is equipollent to 7s 6d per C.
Whereas 3li 16s per C avoirdepois, is but 4li 1s 5d per C stan.
So her Maty loses 6s 6d per C stan. wt. wch in seven years amounts to 72000, besides the loss by the fall of the price in the end of the contract

This loss, if {illeg}|th|e contract should cease at Christmas come twelve month might amount to 50 or 60 thousand poun{ts}|d|s & so is equipollent to about 5s pr C stan. wt in the price.
