Also, any sum in Federal money may be written down as a whole number and expressed in its lowest denomination ; for, when dollars and cents are joined together as a whole number, without a separatrix, they will shew how many cents the given sum contains; and when dollars, cents, and mills are so joined together, they will shew the whole number of mills in the given sum.“ llence, properly speaking, there is no reduction of this money; for cents are readily turned into dollars by cutting off the two right hand figures, and mills by pointing aff three figures with a dot; the figures to the left hand of the clot, are dollars; and the figures cut off are cents, or cents and mills. 2.
