⁂ The standard unit of the above table is the gallon, which is declared, by statute, to be capable of “containing ten pounds avoirdupois weight of distilled water, weighed in the air at the temperature of 62° Fahr., the barometer being at 30 inches.” The pound avoirdupois contains 7000 grains, and it is declared that a cubic inch of distilled water, under the above conditions, weighs 252·458 grains; hence the capacity of the imperial gallon and its divisions are as follows:—
| Imperial | gallon | = | 277·274 | cubic inches. |
| ” | quart | = | 69·3185 | ” |
| ” | pint | = | 34·65925 | ” |
| Fluid | ounce | = | 1·73296 | ” |
| ” | drachm | = | ·21662 | ” |
‡‡‡ The imperial gallon is 1-5th larger than the old wine gallon,—1-60th smaller than the old beer gallon, and—1-32nd larger than the old dry-measure gallon.

⁂ The standard unit of the above table is the mètre, which has been determined to be 39·37079 inches, at 32° Fahr. (Capt. Kater); the English foot is taken at 62° Fahr. The true length of the mètre, reduced to the latter temperature, is 39·370091 English inches; a number
which varies from that in the table only at the fourth decimal figure. It will be perceived that the principle of nomenclature adopted in applying the names, was to prefix the Greek numerals to the decimal multiples, and the Latin numerals to the decimal subdivisions.
