The foregoing method is universal; but may be contracted in some cases, viz. When the rate of exchange is 30d. or 2s. 6d. P crown, 2s. 6d. is 1. consequently in this case every pound sterling contains 8 crowns, wherefore the English money multiplied by 8, will produce the crowns required. Note. If the English money be pounds, shillings and pence, the answer will result crowns, sols and deniers d'or, which being multiplied by 3 throughout, will give the answer in livres, sols and deniers tournois. And if the rate exceed 30d. by an even part thereof, as 321d. exceeds it by 24, of 30, then 2 is contained just once more in the given rate 32 than in the assumed rate 30, viz. 13 times; and 321⁄2 is 3 of itself and 3013 of the same. Therefore 32 30 (1.:) :: +3 or 1:13, or 1- so that if be deducted, the remainder will manifestly be in the ratio to the crowns required as thereof. And the same is shewn of any other rate which exceeds 30d. or 2s. 6d. by an aliquot part thereof, according to the following Rule Rule. If the rates exceed 30d. by an even part of itself, deduet that part of the sterling money from itself, which is denominated by one more than the excess is of 30d. and multiply the remainder by 8. Accordingly let such of the foregoing as fall under this Rule be done. Of Exchange between England and Spain. England exchanges with Spain on the piastre or piece of g for an uncertain number of pence sterling. In Madrid, Cadiz, Malaga, and all the places of trade in the Straits, Mediterrean, Africa, and the West Indies, the Spaniards keep their accounts generally in piastres or dollars, rials, half rials and quartiles; 16 quartiles rial, and 8 rials dollar: Or in dollars, rials and maravadies, reckoning 34 maravadies to the rial, and 8 rials to the dollar.
