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 \Psi 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 63 d. to 68 d. Sterling per millree.
