WEIGHTS AND MEASURES.

WEIGHTS and capacities in England and France are estimated from
certain standard linear measurements. In England, a pendulum
vibrating seconds of time in a vacuum, at the latitude of London,
and at the level of the sea, is assumed as the standard of linear
dimensions; it is 39.1393 inches. This is the standard, too, of all
our measurement of length, capacity, and weight in the United
States. But, like the English, we retain all the old and arbitrary
systems of weights and measures; whereas the French have assumed. a
decimal system in all their measurements that merits the highest
praise and imitation. The linear standard of the French, from which
they derive all other measurements, is called a *métre*.
It is the ten-millionth part of a quarter of the earth's meridian,
and measures 39.371 inches. The *métre* is divisible
decimally in both directions.

The connecting link between the English linear unit and their measures of capacity and weight are as follows:

A cubic inch of distilled water weighed in air with brass weights at a temperature of 62° Fahr., the barometer standing at 30 inches, is equal to two hundred and fifty-two grains and four hundred and fifty-eight one thousandth parts of a grain; of such grains 5760 are required to make the imperial standard troy or apothecaries; pound; and 7000 of such grains make the commercial or avoirdupois pound. The imperial gallon has a capacity of 277.274 cubic inches; and a gallon of distilled water, as above, weighs 10 pounds avoirdupois, or 70,000 grains.

The connecting link between the French linear unit and their measures of weight and capacity, are as follows

A cubic centimétre of distilled water, at its maximum
density, at the temperature of 39.5° Fahrenheit, is the unit of
weights and is called a *gramme*, which is divided decimally
above and below.

A cubic decimétre is called a *litre*, which is the
unit of the measures of capacity, and divisible decimally.
