CHAP. CCCCXXIIII.

Of the Exchanges of Palermo and Mesina, with Barselona.

PAlermo, and Mesina, Exchanges with Barselona, and * 1.1 giveth one Florin of 6 taries, mony of Palermo, to have in Barselona posito 10½ Sols mony currant of Barselona, I demand then for 300 ounces what credit in liuers is due for the same. First, multiply the said ounces by 5 to make them Florins, the ounce being accounted 5 Florins, and it makes 1500 Florins, the which multiplied by 10½ Sols, per Florin makes Sols 15750, which to reduce to liuers, you must cut off the last figure, and take ½ of the rest, and it will be l. 787. 10, which is due at Barselona, 〈 math 〉〈 math 〉

For the proofe of the said Rule, as above divide the said livers * 1.2 l. 787 10 by 10½ Sol, to make them Florin, and it is 1500 Flor. and if there were any remainders, they should be multiplied by 6 and then by 20, to bring them into taries and grains, and for to reduce the said 1500 Flor. into ounces, you must take ⅕ for that 5 Flor. make one ounce, and it will come to 300 ounces, the rule thus appearing right and just.

And for the Exchanges of Palermo and Mesina, with Valentia and Saragoza, it is cast up as above, therefore need not insist further as * 1.3 being easily comprehended.
