The customary weights are likewise referred to the kilogramme. This action fixes the values, inasmuch as the reference standards are as perfect and unalterable as it is possible for human skill to make them at this period. The length of the nautical mile given above and adopted by the U. S. Coast and Geodetic Survey many years ago, is defined as that of a minute of arc of a great circle of a sphere whose surface equals that of the earth (Clarke's Spheroid of 1866). - The U. S. gallon contains 231 cubic inches, and the bushel 2150. 42 cubic inches. The values in these tables are based upon the legal equivalents adopted by Congress in 1866. 2—779 WASHINGTON, D.

Under the direction of the International Committee, two ingots were cast of pure platinum-iridium in the proportion of 9 parts of the former to 1 of the latter. From one of these a certain number of kilogrammes were prepared, and from the other a definite number of metre bars. These standards of mass and length were intercompared without preference, and one of each was selected as the International prototype stand- ard. These two standards are deposited at the International Bureau, and the others were distributed by lot, in Sep- tember, 1889, to the different governments, and are called National prototype standards. Those apportioned to the United States were received in 1890, and are in the keeping of this office. 2–779 ).
