For instance, we may say _met_, _ar_, _lit_, and _gram_; and, in describing the denomination, we may say, in the ascending scale, _dec_, _hec_, _kil_, and in the descending scale, _dec_, _cen_, and _mil_,--indicating respectively 10, 100, 1000, and ⅒, ¹⁄₁₀₀ and ¹⁄₁₀₀₀. Compounding these, we should have, for example, _kilmet_, _killit_, _kilgram_, and _cenmet_, _cenlit_, _cengram_. These abbreviations might be substantially the same in all languages. They would preserve the characteristics of the unabridged terms, so that the simple mention of the measure, even in this abridged form, would disclose the proportion it bears to its fellow-measures. Previous measures have been represented by monosyllables, as grain, dram, gross, ounce, pound, stone, ton. Where a word is often repeated, in the hurry of business, it is instinctively abridged. We shall not err, if we profit by this experience, and seek to reduce the new nomenclature to its smallest proportions. Twelve words only are required by this system. Learning these, you learn all. There are five designating the different units of length, surface, solid capacity, liquid capacity, and weight. Then there are the seven prefixes, being four in the ascending scale, expressing _multiples_, or augmentations, of the metre or other units, derived from the Greek, and three in the descending scale, expressing subdivisions, or diminutions, of the metre and other units, derived from the Latin. These twelve words contain the whole system. In closing this chapter on the unquestionable advantages of the metric system, I must not forget that it is already the received system in the majority of countries. At the Statistical Congress assembled at Berlin in 1863, it appeared that it was adopted partly or entirely in Austria, Baden, Bavaria, Belgium, France, Hamburg, Hanover, Hesse, Mecklenburg, the Netherlands, Parma, Portugal, Sardinia, Saxony, Spain, Switzerland, Tuscany, the Two Sicilies, and Würtemberg. Since then, Great Britain, by an Act of Parliament, has added her name to this list. The first step is taken there by making the metric system _permissive_, as is proposed in the bills before Congress. The example of Great Britain is of especial importance to us, since the commercial relations between the two countries render it essential that these should have a common system of weights and measures. On this point we cannot afford to differ from each other. The adoption of the metric system by the United States will go far to complete the circle by which this great improvement will be assured to mankind. Here is a new agent of civilization, to be felt in all the concerns of life, at home and abroad. It will be hardly less important than the Arabic numerals, by which the operations of arithmetic are rendered common to all nations. It will help undo the primeval confusion of which the Tower of Babel was the representative.
