III. With France. 
Accounts, almoft all over the French dominions, are 
kept in livres, fols, and deniers, but they exchange upon 
the crown or ecu, wliofe par is 4s. 6d. derling. 
j2 Deniers 2= 1 fol or fou 
20 Sols 2= : iivre 
3 Livres 2= 60 fols = 1 crown or ecu. 
At Dunkirk and fome of the northern parts of France, 
they reckon by livres, patarts, and deniers; 15 deniers 2= 1 
patart, and 16 patarts 2= 1 Iivre of 20 fols, as in other pla¬ 
ces. In the French exchanges we mull alfo didinguifh 
between exchange-money and book-money. The ex¬ 
change-money is called d'or ; the book-money is called 
tournois. I f the crow ns, fols, r nd deniers d’or (or exchange- 
money), be multiplied by 3 throughout, it gives livres, 
fols, and deniers tournois); on the contrary, book-money 
divided by 3 throughout, gives exchange-money. 
To change French Money into Sterling. 
Rule. As i crown or 3 livres is to the given rate, fo 
is the French fum given to the derling fought. 
To change Sterling Mor ey into French. As the rate of ex¬ 
change is to 1 crown or 3 livres, fo is the derling fum

IV. With Spain. 
Accounts are kept in Spain feveral ways, but at mod of 
the principal places they make their entries in piadres,, 
rials, and marvidies; reckoning 34 marvidies = 1 rial; 8 
rials = 1 piadre, peio, or piece of eight, old money, by 
which they exchange, whofe par is 4s. 6d. derling. The 
piadre is imaginary, but the rials and marvidies are real. 
London exchanges with Spain in pefos, or pieces of eight, 
old money, of 8 rials = 272 marvidies, and, in new mo.-’ 
ney, of 10 rials = 340 marvidies.
