The Founders Company of London are, by their 
Charter from King James the Firft, authorized and 
direEted to have thejizing and marking of all manner 
of Brafs Weights? to be made or wrought , or to be 
uttered , or kept for Sale , within the City of London, 
or Three Miles from the fame. And the Weights 
delivered to them from his Majesty’s Exchequer , 
and now kept in their Hall, as their Standards for 
the Ufes above-mentioned; are a Pile of flat Brafs 
Troy Weights, from CCLVI Ounces , down to the 
16th Part of an Ounce , all fealed with th z Exchequer 
Seal, and marked with C. R. crowned 1684. and a 
Stamp of the initial Letters of the Maker’s Name : As 
alfo a Set of Bell Brafs Averdupois Weights, fealed 
and marked in like manner. And here the follow- 
ing Trials were made, before the above-named Gen- 
tlemen, by Mr. Read , but with a large Balance, 
commonly tiled for Trials at the Hail, in their Office 
for that Purpofe ; and found to turn with about the 
fame Weight as the former; and alfo with a lefier 
one, turning in like manner under thefe Circum- 
flances, with about half a Grain , which Balance be- 
longed like wife to the Hall, as did alfo the Fenny 
and Grain Weights made ufe of, but which were not 
kept by them as Standard Weights. 
And here it was found, that, on a Medium of 
Four Trials, made in like manner as before, at the 
Exchequer, that 1 5 Founds Averdupois , being their 
14 Founds, and Angle Found Standard Weights, were 
counterpoifed by 2 1 8 Troy Ounces, 1 5 Fenny-weight 
and 23 Grams: Whence the Aver dupois Found is de- 
duced equal to 7001.53? and the Ounce to 437-59 
Troy Grains .
