equalizing saw

A pair of saws on a mandrel at a gauged distance apart, and used for squaring off the ends of boards and bringing them to dimen sions.

When that quantity exists only in the first power we have a Simple Equation, or one of the first degree; if there be a "The Jacobites were equally willing to forget that Athol square or second power of the unknown quantity, had lately fawned on William." -Macaulay: Hist. Eng., ch. xiii. 2. Evenly; equably; uniformly. "If the motion of the sun were as unequal as of a ship, sometimes slow, and at others swift; or, if being constantly equally swift it yet was not circular, and produced not the same appearances, it would not help us to measure time."- Locke . 3. In equal shares or proportions; as, to divide anything equally among several persons. *4. Impartially; with impartiality. IMG:content-1091.png:[blocks in formation] the Equation becomes a Quadratic, or one of the second degree; if the third power be present a Cubic Equation, or of the third degree. It is rarely that a higher power than the cube of the unknown quantity has to be dealt with. When such cases occur the equation is a Biquadratic, or one of the fourth degree, an Equation of the fifth, of the sixth, of any degree. 2. Astron .: Any sum to be added or subtracted to allow for an anomaly or a special circumstance affecting the exactne of a calculation. If, for instance, the orbit of a planet were calculated on the supposition that its orbit was circular when in reality it is elliptical, a small number would require to be added or subtracted to make the calculations accurate. That small sum would be the astronomical equation. If the movements of the planets be
