       (a) (Quantitative Analysis) Denoting a solution of such

    Usage: Regular and ordinary are popular terms of well-known
           signification; normal has now a more specific sense,
           arising out of its use in science. A thing is normal,
           or in its normal state, when strictly conformed to
           those principles of its constitution which mark its
           species or to the standard of a healthy and natural
           condition. It is abnormal when it departs from those
           principles.

    Note: The term normal is also used to denote the distance
          along the normal line from the curve to the axis of
          abscissas or to the center of curvature.
