Usance from Venice, Hamborough, &c.

NOte also, that usance from Venice to London is three months from the date of the Bill of Exchange, and from Hamborough to London, and so from London to Hamborough Bills of Exchange are usually made payable at two months after the date of the Bills, and accordingly the price currant of Exchange from London to Hamborough is valued and set down at two months from the date; the price currant from London to Venice and Ligorn at three months, and for Antwerp, Amsterdam, Middleborough, Lisle, Rotter∣dam, Paris, and Rouen at one month, or

single usance; and so we call one month, usance; two months, double usance; three months, treble usance.
