Inch
the twelfth part of a foot. Inch is another form of ounce, the twelfth part of a pound Troy. Both are from the Latin uncia. The inch is the relic of an old duodecimal system. It was divided originally into twelve lines. According to an English statute of 1324, an inch is the length of "three barleycorns, round and dry." The English inch is a trifle shorter than the Scotch inch. It is not a scientific measure, that is to say, if all the graduated rules were destroyed the exact inch could never be reestablished by means of any measure existing in nature. In Iowa an inch of cream has been defined by statute as a half gallon. The miner's inch is the amount of water per minute running through a hole an inch square.

To Calculate the Vibrations of a Pendulum. Multiply together the number of teeth of the wheels, starting with the one that carries the minute hand (which makes one revolution per hour), but omit the escape wheel. Multiply together the numbers of leaves of the pinions, commencing with the one that engages with the center wheel. If the first product be divided by the second, the number obtained gives the number of revolutions of the escape wheel in an hour. Multiply this figure by twice the number of teeth of the escape wheel, and the product is the number of single vibrations performed by the pendulum in one hour. The vibrations of a balance may be calculated in precisely the same manner.

Incidence
the manner of falling on, or the direction in which a body, or a ray of light, heat, etc., falls upon any surface. Angle of incidence, an angle formed by two straight lines, one the line of incidence of a ray of light or heat, or of an elastic body moving to strike a plane, and the other a perpendicular to that plane. The angle formed by the perpendicular and the line of departure taken by the elastic body is called the angle of reflection, and is always equal to the former one. Line of incidence, the straight line taken by a ray of light or heat, or an elastic body moving to strike a plane at an acute or right 1 angle.

Inclination
the mutual approach, tendency, or leaning of two bodies, lines, or planes toward each other, so as to make an angle where they meet, or where the lines of their direction meet. This angle is called the "angle of inclination." In pharmacy, the act by which a clear liquor is poured off from some fæces or sediment by only stooping the vessel; also called decantation.

Inclined Plane
one of the mechanical powers. It consists of a plane, inclined obliquely to the horizon. The velocity acquired by a body descending an inclined plane is the same as if it had fallen perpendicularly from the same height. The inclined plane is used for the descent of bodies; also for the ascent, by vehicles, etc., of hills far too steep to be directly scaled by wheeled carriages.

Inclined Strata

Incommensurable
a state of deprivation or non-existence (as regards two kindred quantities) of a common unit, or, more strictly, a magnitude which cannot be measured by another, taken as unity. Two quantities of the same kind are incommensurable with respect to each other, when they have not a common unit-that is, when there is no quantity of the same kind so small that it is contained in both an exact number of times. Thus the diagonal and side of a square are incommensurable, for it has been shown that if we denote the side of the square by 1, the diagonal will be denoted by the square root of 2; but the square root of 2 is incommensurable with 1, because the square root of an imperfect square cannot be expressed in exact terms of 1.

Incommunicable Axiom, The
It was believed that all magical science was embodied in knowledge of this secret. The Axiom is to be found enclosed in the four letters of the Tetragram arranged in a certain way; in the words Azoth" and "Inri" written kabalistically; and in the monogram of Christ embroidered in the labarum. He who succeeded in elucidating it became humanly omnipotent from the magical standpoint. 66
