This will be 6.483 English feet less than the English (7.) rood every
way, and 1311 square feet less in its whole contents; that is to say,
about one-eighth; in which proportion, also, 4 roods will be less
than the present acre.
MEASURES OF CAPACITY.
Let the unit of capacity be the cubic foot, to be called a
bushel. It will contain 1620.05506862 cubic inches, English; be
about one-fourth less than that before proposed to be adopted as a
medium; one-tenth less than the bushel made from 8 of the Guildhall
gallons; and one-fourteenth less than the bushel made from 8 Irish
gallons of 217.6 cubic inches.
Let the bushel be divided into 10 pottles;
Each pottle into 10 demi-pints;
Each demi-pint into 10 metres, which will be of a cubic inch each.
Let 10 bushels be a quarter, and
10 quarters a last, or double ton.
The measures for use being four-sided, and the sides and
bottoms rectangular, the bushel will be a foot cube.
The pottle 5 inches square and four inches deep;
The demi-pint 2 inches square, and 2 1/2 inches deep;
The metre, an inch cube.
WEIGHTS.
Let the weight of a cubic inch of rain water, or the thousandth
part of a cubic foot, be called an ounce; and let the ounce be
divided into 10 double scruples:
The double scruple into 10 carats;
The carat into 10 minims or demi-grains;
The minim into 10 mites.
