At Paris, Rouen, Lyons, &c. books and accounts are kept in livres, sols, and deniers; and the exchange with Britain is on the crown, or ecu, of 3 livres, or 60 sols Tournois. Britain gives for the crown an uncertain number of pence, commonly between 30 and 34, the par, as mentioned above, being 29 $\frac{1}{2}$ d.

In Lisbon, Oporto, &c. books and accounts are generally kept in rees and millrees; and the millrees are distinguished from the rees by a mark set between them thus, 485 $\frac{1}{2}$ 372; that is, 485 millrees and 372 rees.

Britain, as well as other nations, exchanges with Portugal on the millree; the par, as in the table, being 67 $\frac{1}{2}$ d. sterling. The course with Britain runs from 63d. to 68d. sterling per millree.

In Madrid, Bilbao, Cadiz, Malaga, Seville, and most of the principal places, books and accounts are kept in piafres, called also dollars, rials, and mervadies; and they exchange with Britain generally on the piafre, and sometimes on the ducat. The course runs from 35d. to 45d. sterling for a piafre or dollar of 8 rials.
