If the Paymaster of her MajtsMajestys forces in Spain have received several summs of Peru Mexico & Peru Dollars for paying those forces & have carried them to the Mints of K. Charles to be coined into two-ryal pieces: the Commissioners are to enquire what number of Dollars every Paymaster received, what was the weight of them before melting, what was the weight of the Ingots produced by melting, then what silver was got out of the sweep, whether the weight of this silver & the Ingots equalled the weight of the Dollars wanting only the 300th part of the whole weight, what number & weight of two ryal pieces wereas coined out of this weight of Ingots & silver extracted fincluding the seigniorage whether theis weight of the two ryal pieces equalexceed the weight of the Ingots & silver got out of the sweep by the weight of the allay put to the Ingots, th & silver that is by about the hundredth part of the whole weight, what number of two ryal pieces were deteined fo whether the number of the said two ryal pieces gbe to the number of Dollars or such proportion assuch as ought to be coined out of that weight, that is the number of two ryal pieces in 20 spanish ouncesabout 109 pieces out of every twenty ounces, or about 10934 pieces out of every 21 Dollars. Also how many pieces have been deteined for seigniorage & & for melting the silverDollars into Ingots & how many the Paymaster has received out of the Mint for the Queens service & whether the number received out be in such proportion to the number of ounces coined, or to the number of Dollars melted down, to be coined, as by the rules above described it ought to be. And [whether the number of Dollars & two ryal pieces wchwhich the Paymasters have charged themselves wthwith in their Accounts be the same wthwith the number number of Dollars received by the Melter for the melting pot & of two ryal pieces delivered from the Mint according to the Melter & the Mint. Or what proofevidence have the Paymasters by Receipt or otherwise‡‡by the books of Melter & of the Mint by Receips or Certificates or living witnesses that they have 190caused allthe full number ofall the Dollars received by them from the merchant to be melted & coined & that they have charged themselves in their accounts with all the two ryall pieces wchwhich they have received from the Mint.

If any dispute should arise in Spain about the coarseness of the two Ryall pieces wchwhich cannot be decided without an assay, the best way to o decide the Question by yethe assay is this. Let a pound weight of or half a pound weight of yethe two Ryall pieces be melted into an a lump, & let the same weight of Mexico Dollars with a fur & pillar Dollars be also melted in a lump. Let assays be cut off from these two lumps by a skilful Assayer & weighed for the fire by the assay weights for the fire Let them also be weighed against one another in yethe assay-scales to see that they be exactly of athe same weight before they be wrapt up in lead. Then And when yethe lead is blown off from the last let the fire abate gently of it self till the silver is ready to congealleast the silver by cooling too suddenly spring into the fire.. Then like the And when the assay drops are taken out of the fire let them be weighed in the Assay scales against one another &c exactly to find the difference of their weightAnd let one or two of the CommrsCommissioners (or persons appointed by them) see all this done.. Then say, As the weight of the assay drop of the two Ryal pieces is to the difference so is theweight of the Ingots coined to the weight of the all other assay drop so is the weight of the silver fine silver in a pound weight of Dollarstwo Ryal pieces to the weight of the fine silver in a pound weight of yethe Dollars & so is the pound weight of the weight of all the silver Ingots of silver coinedunto two Ryall pieces, to the weight of all the two Ryal pieces wchwhich ought to be coinedproduced out of those Ingots by coinage. And when they have the whole weight & the number of two Ryal pieces in 20 pound weight they will thence know the number of two Ryal pieces in the whole weight by the Rule of three. And when they have learnt at the Mint what proportion is deteinedto be taken for seigniorage, or what the Imp they will know what number the Paymaster ought to receive out of the Mint.
