CHAP. CCCC.

Of Examples of Exchanges practised at Florence, and how the same are to be calculated.

I Have shewed in the generall Exchanges of Florence, * 1.1 with how many other places the said City is found to exchange with, and there also shewed the common rates, how the same is observed to rule, which every day is so subiect to alter, that no set price can be peremptorily set downe fot the same, yet in it selfe it is so beneficiall, that thereby the ignorant may bee furthered to make his accounts either in Draughts or Remittances: the way of making which accounts, upon this place, now remaineth here to be handled, observing the same with so many other places, as may make a man capable to understand the same, with any of the rest here omitted.

And by the way it is observable here, that all Exchangers here * 1.2 doe keepe their accounts in Crownes, Sols, and Deniers of Gold, of Lire or Livers 7½ of that money per Crowne, the which are cast up by 20 and by 12, because that 20 Sols of gold doe make one Crow. and 12 Den. one Sol.
