CHAP. CCCLI.

Of the Exchanges of Naples with Mesina.

NAples exchangeth with Mesina, and giveth posito ducc. Ducc. * 1.1 115 〈◊〉〈◊〉 to have in Mesina Crow. 100 of Tar. 13 of that mo∣ny, I demand how many Crownes of Taries 13 shall I have there for Ducc. 2348. 3. 8, to doe which working, as by the pre∣cedent Rules, I say: If graines 115 〈◊〉〈◊〉 make one Crowne of 13 Ta∣ries, what will graines 234868 make, and multiplying the re∣mainder of the division by 52, to bring them into halfe carlins, be∣cause that 13 Taries are worth 26 Carlins, and by this working it maketh Crownes 2035 〈◊〉〈◊〉 which abridged are 〈◊〉〈◊〉, or otherwise multi∣plying the remainder of the division by 13 and then by 20 to bring them into Taries and graines, which will be the easier to compre∣hend, but the reason why I have otherwise demonstrated it, is be∣cause herein I would follow the method and manner of the Mer∣chants of Naples, who in their accounts are accustomed to doe as above is shewed, and to reduce the said Crowns 2035 9/13 into ounces, you must multiply by 13 to bring them into Taries, adding to the multiplication 9 for the 9/13 and they will be Taries 26464, from which cutting the last figure and take 〈◊〉〈◊〉 of the rest to make them ounces, because that 30 Taries is an ounce, and the remain∣der of these thirds are tens of Taries, to the which adding the fi∣gure cut off, which are so many Taries, as must be placed after the ounces, and it will make Ounces 882. 4, and for so much shall Naples have credit in the said place of Mesina for Duc. 2348. 3. 8.
