CHAP. CCCCIII. Of the Exchanges of
Florence with Venetia.
* 1.1FLorence doth Exchange with
Venice, and giveth posito Crow. 81½ of
Gold, to have Duc. in Banco 100 of Livers
6⅓ I demand then, for Crow. 2037. 10. of Gold, how many Duc. shall Florence have credit in
Venice? To do which, bring the Crow. 81½ into half Crowns, mul∣tiplying them by 2, and so in the same manner the said sum of Crow. of Gold, adding half a Crown for the
10 Sols: then say by the Rule of Three, If the half Crowns produced of the price of the Exchange, give at Venice Duc. 100, what will the half Crowns give, proceeding from the said sum of Crow. of Gold? and so by adding two cyphers for the 100, and dividing the same, it will make Duc. 2500, which
Florence is to have in Venice; and if there were any remaining of the division, they must be multiplied by 24, to make them
Grosses, because that 24 Gross. make a
Duc. of Lib. 6. 4 Sols. Example:

Account is more evident, when Venice doth rechange for Florence.
