PRACTICE.

Practice is an easy method of finding the whole value of any given number of ounces, pounds, gallons, hogsheads, &c. by having the price of one given.

NOTE: In some cases Multiplication of Federal Money, or Compound Multiplication, will be found preferable to this Rule, but in many, this is zo be preferred.

When the given price is less than a penny, divide the

CASE II. When the given price is an aliquot part of a shilling, divide the given number by the aliquot part, and the quotient will be the value in shillings, which must be reduced to pounds.

If the given price is not an aliquot part of a shilling, divide by some aliquot part, then take parts of that aliquot part, &c. Id. | II 5963 at id.
