And current money is reduced to bank money by reversing the operation. And in like manner may picoli money be reduced to current or to bank money, and the contrary.

Books and accounts are generally kept in pezzos, soldi, and denari; but some keep them in lires, soldi, and denari; and 12 such denari make 1 soldi, and 20 soldi make 1 lire.
The pezzo of exchange is equal to 5½ lires; and, consequently, exchange money is 5½ times better than the lire money. The course of exchange runs from 47d. to 58d. Sterling per pezzo.
