1 Marc = 8 ounces = 64 Gros = 192 Deniers = 160 Esterlings = 320 Mailles = 640 Felins Grains = 778 ounces Troy – 2gr.

1 Ounce = 8 Gross = 24 Deniers = 20 Esterlings = 40 Mailles = 80 Felins = 576 Grains. 1 Denier = 24 grains. A double Lewis d'or new out of the Mint weight 8dwt 16gr. Thirty six & a quarter Lewi dors make a French mark of Eight ounces, wanting only about 23 of the Remeydy wchwhich Remedy is the 40th part of the ounce French or almost 12 grains English & 81112 silver Lewises make a Mark French wanting only 34ths of the remedy, wchwhich remedy is about 36 grains sterling in yethe Mark. And thence the silver Lewis weighs 17dwt 1223gr new out of the Mint. If 1 Mark = 778 ounces Troy, A Lewidor new out of yethe Mint weight 4dwt 8120gr & a silver Lewis 17dwt 1278gr. so that a Lewidor is to La Lewis as [1 to 4490, or to 180 1 to 4122, or] 22 to 89. A LeDouble Lewisdors new out the Mint one with about weighs 8dwt 16gr, a new sil & by the assay the french Gold money is found sometimes 34legr sometimesoftener 14legr most commonly 12legr worse never standard. It may be recconed 716legr or in a round number 12 legr worse then standard Before the coynage of Pistoles which began in Feb 17001 those current in orour markets weighed one with another 4dwt 718gr: but the heavy ones being melted down they do not now weigh one wthwith another above 7dwt 6gr or 7dwt 612gr. They are well aequally assaid & sized & the double Pistoles are generally heavier in proportion then the single ones being less worn. TheyThey are both single & double well allayed & sized. Silver Lewises new out of the Mint weigh one with another 17dwt 13gr or 1314gr but in every six or seven years wearing lose a grain, more or less. They are less equally allayed & sized then the gold. The assays of ten pieces were as follows. 1st Coyned 1651 wors 24wt ob. 2d coynd 1679 better 1wt ob. 3d coynd 1680 stastandard. 4th coynd 1682 better 4wt. 5t coynd 1687 stastandard. 56 coynd 1690 restamp 1694 wors 1wt. 7th 8th 9th & 10th worse sta.standard sta. better 1dwt. worse viijdwt. One wthwith another worse 710dwt. These & two others weighed one with another 17dwt 6g, the eight heaviest of them 17dwt 12 the two heaviest 17dwt 1314gr, the two lighted 17dwt 312gr being lightned by wearing The French standard is 11 ounces fine & one ounce of allay both for gold & silver They cut a Mark into 3614 Pistoles & 81112 silver Lewises, abating part ofallowing for the remedy. The whole remedy for gold is two Felins (or about 1145gr grains English) per Marc & for silver three six fi three times as much. And of this they abate about 7gr per Marc of gold & 21gr prper Mark of silver in the weight of the money so that the French Marc is (3614 Pistoles + 7gr = 81112 white Lewises + 21gr =) 7 ounces 17dwt 9gr Troy quam proxime. And therefore yethe ounce French is to yethe ounce Troy of the Exchequer & Tower as 650 to 61. The remedy of Allay is
