FEDERAL MONEY.

Federal Money is the coin or currency of the United States. This is the most simple and easy of all curren, cies. It increases in tenfold proportion like whole num: bers. Thus 10 mills (m.) make 1 cent, marked C, 10 cents make 1 dime,

d.
10 dimers, or make 1 dollar

,
100 cents,
10 dollars make
1 Eagle, *

E. Hence it follows that any sum in federal money may be performed as in whole numbers

The dollar is the money unit; and to distinguish dollars from the smaller denominations, a point, or comma (,) called a separatrix, is placed between them and the other inferior denominations; consequently, the first figure at the left hand of the separatrix is dollars and the rest are eagles. And the first figure at the right hand is dimes, the second cents, and the third mills.

But as the denominations of this Money increase in a

* The Eagle is a gold coin. Dollars and dimes are silver coins, and cents are copper coins. These are real coins. There are also half Eagles, half dollars, half dimes, and half cents, real coins.

There is no coin so small as the mill, that being only imaginary. Müll is contracted from Mille, the Latin for thousands; cent from centum, the Latin for hundreds; and dimne from disme, the French for tenth.

tenfold proportion like whole numbers, it is evident that all the figures at the left of the separatrix, may be called dollars, and those at the right, cents and mills. That is, the first two at the right, cents, and the third mills; and this is the usual way of expressing it in commercial business.
