The reason why I have beene induced to set downe the briefe * 1.2 method of calculating the Exchanges here is, that as it is to be un∣derstood that the rate of the Exchange at the payment is regula∣lated for the next ensuing payment from that day, so must it al∣so be understood that the neerer the time is, to the day of the next paiment ensuing, the lesser consequently is the rate of the Exchange, for that paiment to be accounted, and because in many contracts that are made there in private bargaines, between mer∣chant and merchant, it is oftentimes found that the time of pay∣ment prefixed by agreement is sometimes 2, 3, or 4, or more Fairs or payments to come and succeed, and thereto is oftentimes to be considered the remaining time running to the first payment ensuing, therefore in this case, I have for the easier and better reckoning of him that sels a commodity, and of him that doth buy the same, set downe the easiest and briefest way how to make his account of the time to runne, which here I have set downe to the common terme of 10 payments, which at 2 〈◊〉〈◊〉 per cent. makes 25 per cent.
