“ An ampere, the practical unit of current, is the electromotive force of 1 volt against a resistance of 1 ohm. It is the tenth part of the absolute unit. An ordinary dry cell gives a current of about 2 amperes, a Daniels wet cell, 1 ampere. Dry cells differ somewhat in strength.
A volt, conversely, is the electromotive force, or “electric pressure,” which, flowing in a conductor having a resistance of 1 ohm, will yield 1 ampere of current. The ordinary dry cell, when fresh, has an electromotive force of about 2 volts. ”

“ The virtue of the solution depends on the fact that neither the solution nor the precipitation is complete; the proportion of alcohol must be regulated to prevent more than a small part of the chemical salts from precipitation. ”

“ The construction and evolution of the system of electrical units now in general use began in Europe where the metric system originated. Two of the basic units, the centimeter and the gram, are metric units; the second of time is universally employed in time measurements.
The meter, 3.2808 feet = 39.37 inches, is theoretically the one ten-millionth part of the earth’s quadrant ”

“ The square centimeter is the unit of area. 1 sq cm or cm2 = 0.001076 sq ft = 0.1 550 sq in.
The cubic centimeter is the unit of volume. 1 cc = 0.0000353 cu ft = 0.061 cu in.
The unit of density is numerically the same as the specific gravity. It is the rate of 1 gram per cubic centimeter.
The unit of velocity is the velocity of 1 centimeter per second; 1 cm per second = 0.0328 foot per second = 0.0224 m. per hour.
The unit of acceleration is the rate of a unit of velocity per second or 1 centimeter per second, per second. ”

“ The glass must be thin enough and elastic enough to yield slightly to changes in atmospheric pressure. About 1 inch of air space in the tube adds to the sensitiveness of precipitation. An increase in pressure causes the precipitation to extend nearly to the top of the solution; a decrease causes increased solution and a settling to the bottom of the tube. ”

“ A solution consisting of 5 grains of cobaltic chloride, 50 grains of gelatine and 1 fluid ounce of water is a good porportion. There must be a complete emulsification of the gelatine. A strip of unsized paper wet with the emulsion is normally pink in moist air, violet in moderately moist air, and blue in dry air. When the winter fires are on in dwellings, the strip of paper is persistently blue. Ordinarily it does not begin to turn until the moisture of the air is about 75 per cent.
Ozone Test Papers.—Qualitative tests for ozone are often desirable. ”

“ Sidereal year = 365.2563578 days Sidereal day = 23 h, 56 min, 41 sec Mean solar day in sidereal time = 24 h, 03 min, 56.5 sec Mean distance of the earth from the sun = 92,800,000 miles Physical Velocity of light per second = 186,337 miles Velocity of light per second = 299,878 kilometers Velocity of sound per second in dry air at 0° C = C feet Velocity of sound per second in dry air at 32° F = F feet The formula for Centigrade, and for Fahrenheit scales is practically the same. ”

“ A more accurate result will be obtained by using 3.94 as the divisor. Multiplying by .04 reduces millimeters of rainfall to inches of rainfall.
The practical unit of wind velocity is 1 meter per second—that is, 100 times the C. G. S. unit. ”
