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 29d.

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, 485 372; 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 67d. sterling. The course with Britain runs from 63d. to 68d. sterling per millree.
