TABLE II. OF THE MONEY OF THE JEWS, GREEKS, AND ROMANS, WITH THE VALUE IN STERLING AND FEDERAL MONEY.* In this estimate the value of gold is to that of silver nearly as Authors differ respecting the precise value of ancient money. The common estimate is here given, which is, at least sufficiently near the truth. Aureus 25 denarii 888020 16 8 0 16 12 3 5842 This ratio of the aureus to the denarius is that mentioned by Tacitus. TABLE III. OF MEASURES OF LENGTH AND CAPACITY AND WEIGHTS OF VARIOUS COUNTRIES. THE table of English and American measures has been given under compound addition. Compared with the French measure, the English inch is 0.2539940539585323821235+ of a French metre. 1 Fall 6 ells, 48 Scotch acres are very nearly 2231 inches. 61 acres. For the measure of Wheat, Peas, Beans, Rye, and White Salt. 100 Bolls equal 409 bushels, Winchester measure. For Barley, Oats, and Malt. 100 Bolls equal 596 bushels, Winchester measure. Note. The Boll varies in different parts of Scotland. IRELAND. The Irish and English foot and yard are equal.

Metre, Deca-metre 10 metres, Deci-metre metre, Metre, 66 Quadrant of the Meridian, 100 French degrees, 90 English degrees. * France is the only nation, which has established an invariable standard of measure. The linear unit of the French measure is the metre. By accurate observations and calculations the length of the meridian from the Equator to the pole, which passes through the city of Paris, was ascertained to be 5130740 toises of six feet each of the ancient French measure. This number of toises is equal to 30784440 French feet, or 32809167 English feet. The metre is one ten millionth part of this arc of the meridian, or 3078444 feet, which is 3 feet 31 lines, and 295936 of a line of the former French measure. All other ineasures are derived from the metre. 1000000 In England, it has been proposed to make the length of the pendulum to vibrate seconds at London, the standard of measure. At the level of the sea, and when the temperature is 62d. Far. and in lat. 51d. 31/8.4" N. the length of the pendulum to vibrate in a second is 39-1336 inches, English, as very accurately determined by Capt. Kater. According to Capt. Kater's measure, the French metre is 39-37076 inches English, at the same temperature, and may be taken with sufficient accuracy to be 39:371 inches. These measures will vary a little according to the scale on which they are estimated. If Troughton's scale of 36 inches be taken as the standard, General Roy's Scale is 36-00036 inches, and Bird's Parliamentary standard of 1758, is 26-00023 inches. And if the scale of 1758 be the standard, Troughton's scale is 35.99977 inches. According to Mr. Magsler, the French metre is 3-23168733 feet on Troughton's Scale. Degree 54 min. Eng. 100 min. Fr.

By a decree of 1812, the Toise, Aune, Foot, &c. are allowed to be the denominations of measure for the common people of France, in the following ratios to the metre. Toise 2 metres, 6 56 English feet nearly. 0.5468 0.2734 3.9371 762 854 cubic inches. The old litron 40-39345517 French cubic inches, by statute, but the common litron is 48-8224 English cubic inches. The ratio of the French to the English foot here assigned is very little dirferent from 1 to 1665, which was formerly considered as the true ratio. |
