•  State of being ample; extent of surface or space; largeness of dimensions; size.  [1913 Webster]

  "The cathedral of Lincoln . . . is a magnificent structure, proportionable to the amplitude of the diocese."  [1913 Webster]
•  Largeness, in a figurative sense; breadth; abundance; fullness.  [1913 Webster]
•  The arc of the horizon between the true east or west point and the center of the sun, or a star, at its rising or setting. At the rising, the amplitude is eastern or ortive: at the setting, it is western, occiduous, or occasive. It is also northern or southern, when north or south of the equator.  [1913 Webster]
•  The horizontal line which measures the distance to which a projectile is thrown; the range.  [1913 Webster]
•  The extent of a movement measured from the starting point or position of equilibrium; -- applied especially to vibratory movements.  [1913 Webster]
•  An angle upon which the value of some function depends; -- a term used more especially in connection with elliptic functions.  [1913 Webster]

Magnetic amplitude, the angular distance of a heavenly body, when on the horizon, from the magnetic east or west point as indicated by the compass. The difference between the magnetic and the true or astronomical amplitude (see 3 above) is the “variation of the compass.”
