accordingly. A pint is not a pound, or vice versa, tradition notwithstanding. The weight of a pint of any solution depends wholly upon the specific gravity of such solution. A pint of water will not be of the same weight as a pint of 50 per cent. alcohol, but their weights will be in the proportion of 1.000 to 0.9182, their specific gravities. If this is borne in mind by the carbonator, dealers in essential oils will be spared the trouble of explanations, which in many cases are unintelligible to the purchaser Measures.

The unit of all metric measures is the meter (French, metre), and this is the ten-millionth part of the quadrant, or fourth part of the terrestrial meridian, the quadrant being the distance from the equator to the pole. The cube of the tenth part of a meter, denominated liter (French, litre), was adopted as the unit of measures of capacity. The weight of the one-thousandth part of a liter of distilled water at its greatest density (4° 0.) was denominated gram (French, gramme), and adopted as the unit of weight. The subdivisions of all measures are named by prefixing to the name of the unit the Latin numerals deci (.1), centi (.01, and milli (.001), and the larger denominations by prefixing the Greek num-erals deka (10), hekto (100), kilo (1000), and myria (10,000).
