A middle state between two extremes; thus we say, arithmetical mean is half the sum ofany two quantities : as — = arithmetical mean between a and b. Geometrical mean is the square root of the product of any two quantities ; that is, y/ a b is the geo-metrical mean between a and b. MEASURE. Measure denotes any certain quantity with which other homogeneous quantities arecompared.—See Weights and Measures. MECHANICAL POWERS. Power is a compound of weight, multiplied by its velocity; it cannotbe increased by mechanical means. The weight is the resistance to
