    • n level An instrument for determining the plane of the horizon, or the plane perpendicular to the direction in which bodies fall under the action of gravity. The simplest instrument used for this purpose is the plumbline. This is now superseded for most purposes by the bubble- or spirit-level, which consists of a frame of some kind firmly holding a glass tube, closed at the ends, nearly filled with anhydrous ether, or a mixture of ether and alcohol, and having its inner surface on the upper part ground into the form of the outer part of an anchor-ring. Fine levels have besides a graduated scale either on the glass or on a metallic rule set against it, so as to mark the precise position of the bubble. Most fine levels are provided with a chamber so contrived that the length of the bubble can be altered. The spirit-level is usually reversed in use, and the mean of its two indications adopted. The spirit-level is an attachment of most geodetical instruments; and there is a special instrument called a level or leveling-instrument (which see).
    • n level An imaginary surface everywhere perpendicular to the plumb-line, or line of gravity, so that it might be the free surface of a liquid at rest. Every such surface is approximately that of an oblate spheroid, as the sea-level, for example, is; but for most of the purposes of ordinary life it is convenient, and occasions no sensible error, to confound this surface with its tangent plane at the point referred to—the plane of its horizon. The vertical distance from any given lower level (in the stricter sense of the word), A, to a given higher level, B, will vary with the latitude; but the work required to raise a given weight from A to B is everywhere the same. The level or horizontal surface is ordinarily spoken of as belonging to anything lying or moving upon it, or to a liquid whose free surface in equilibrium will coincide with a portion of it, and frequently indicates. in addition, some reference to some other object having the same or a different vertical elevation. Thus, we speak of the level of a station (often with reference to some standard of elevation), or of the level of the sea; a liquid is spoken of as finding its level; A is said to be on a level with B, or A and B are on a level or on the same level.
    • n level Hence Figuratively, degree of elevation as regards standing, condition, or action; a height reached or aimed at, from a social, intellectual, or moral point of view. The idea of comparison, relativity, or parallelism is prominent in this as in the literal signification of the word; and a natural or normal level is often spoken of, after the analogy of a free liquid surface.
    • n level An extent of land-surface approximately horizontal and unbroken by irregularities; a plain.
    • n level The point-blank aim of a missile weapon, including the line of fire and the range or distance the missile is carried without deflection; hence, purpose; aim.
    • n level In mining, a drift or nearly horizontal excavation made in opening a mine. Levels are run to connect shafts and winzes, so as to open and make ready for stoping a certain amount of ground. In a mine regularly opened on a permanent vein, the levels are usually from 60 to 100 feet apart, but vary in position with the varying richness of the lode.
    • n level A leveling-instrument. See clinometer-level and leveling-instrument.
    • level Lying in or constituting a horizontal surface; not having one part higher than another; horizontally even or flat; not sloping: as, level ground; a level floor or pavement.
    • level Lying in such a surface that no work is gained or lost in the transportation of a particle from any one point of it to any other; equipotential.
    • level Existing or acting in the same plane or course; continuing without change of relative elevation; even with something else.
    • level With reference to color, especially in dyeing, even; unbroken; uniform.
    • level Equal in rank or degree.
    • level Well-aimed; direct; straight; in a right line; conformable.
    • level Steady; in equipoise.
    • level Well-balanced; of good judgment: as, a level head.
    • level Synonyms and Level, Flat, Even. In regard to the surface of land, flat is a depreciative word, indicating lowness or unattractiveness, or both; level conveys no slur, and is entirely consistent with beauty: as, flat marshes; level prairies. Flat is a rather more absolute word than level. That which is flat or level is parallel to the horizon; that which is even is free from inequalities: as, an even slope.
    • level To make horizontal; bring into a plane parallel to the horizon, as by the use of a leveling-instrument: as, to level a billiard-table.
    • level To reduce or remove inequalities of surface in; make even or smooth: as, to level a road or walk.

    • n level The correction for level of an astronomical instrument; the deviation of its axis from exact horizontality.
    • n level In landscape-gardening, one of the horizontal surfaces in which an irregular piece of land may be arranged. By the use of different levels the designer may place various features of his design above or below the eye.
