THE table of English and American measures has been given under compound addition.

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 3.078444 feet, which is 3 feet 11 lines, and 295 936 of a line of the former French measure. All other measures 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 pendulun 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, Genera! Roy's Scale is 36 00036 inches, and Bird's Parliamentary standard of 1758, is 36 09023 inches. And if the scale of 1758 be the standard, Troughton's scale is 35-99977 inches. According to Mr. Hassler the French metre is 3.28168733 feet on Troughton's Scale., French feet. English feet. 307844-4 328091.67 3078-444 3280-9167 Degree 54 min. Eng. 100 min. Fr.
