In the money of account the dollar is considered as the unit all other denominations being valued according to their distance from the dollar's place. A point or comma must be placed after the dollars to separate them from the lower denominations; then the first figure at the right of the comma is dimes, the second cents and the third mills; but in reckoning, the two first are called so many cents, using the dimes for the tens' place of cents.* When the cents in any sum are less than 10, a cipher must be put in the place of dimes, or tens' place of the cents, before any operation is performed.

The coins of the United States are three of gold, six of silver and two of copper. The gold coins are called an eagle, half eagle and quarter eagle; the silver, a dollar,half dollar, quarter dollar, double dime, dime and half dime; and the copper, a cent and half cent.

NOTE. A carat is not any certain quantity or weight, but, of any weight or quantity; which minters and goldsmiths divide into four equal parts called grains of a carat.
