In Memoriam It is with deep regret and sorrow that we announce the sudden death of Brother James E. McLean Vice-President of Local No. 1, I. U. E. C., New York City, he having passed away Tuesday, December 5th, as a result of injuries received from falling down an elevator shaft the day previous. We extend our heartfelt sympathies to his family and friends in this their hour of The Metric System The Metric System is based on the Meter which was designed to be one ten-millionth (1-10,000,000) part of the earth's meridian, passing through Dunkirk and Formentera. Later investigations, however, have shown that the Meter exceeds one ten-millionth part by almost one part in 6400. The value of the Meter as authorized by the United States Government, is 39.37 inches. The Metric system was legalized by the United States Government in 1866. The three principal units are the Meter, the unit of length; the Liter, the unit of capacity, and the Gram, the unit of weight. Multiples of these are obtained by prefixing the Greek words: deka (10), hekto (100), and kilo (1000). Divisions are obtained by prefixing the Latin words: deci (1-10), centi (1-100), and milli (1-1000). Abbreviations of the multiples begin with a capital letter, and of the divisions with a small letter, as in the following tables: Note The liter is equal to the volume occupied by cubic decimeter. Note-The gram is the weight of one cubic centimeter of pure distilled water at a temperature of 39.2° F.; the kilogram is the weight of 1 liter of water; the ton is the weight of 1 cubic meter of water.
