Mass \Mass\, n. [OE. masse, F. masse, L. massa; akin to Gr. ? a
   barley cake, fr. ? to knead. Cf. {Macerate}.]
   1. A quantity of matter cohering together so as to make one
      body, or an aggregation of particles or things which
      collectively make one body or quantity, usually of
      considerable size; as, a mass of ore, metal, sand, or
      water.

            If it were not for these principles, the bodies of
            the earth, planets, comets, sun, and all things in
            them, would grow cold and freeze, and become
            inactive masses.                      --Sir I.
                                                  Newton.

            A deep mass of continual sea is slower stirred To
            rage.                                 --Savile.

   2. (Phar.) A medicinal substance made into a cohesive,
      homogeneous lump, of consistency suitable for making
      pills; as, blue mass.

   3. A large quantity; a sum.

            All the mass of gold that comes into Spain. --Sir W.
                                                  Raleigh.

            He had spent a huge mass of treasure. --Sir J.
                                                  Davies.

   4. Bulk; magnitude; body; size.

            This army of such mass and charge.    --Shak.

   5. The principal part; the main body.

            Night closed upon the pursuit, and aided the mass of
            the fugitives in their escape.        --Jowett
                                                  (Thucyd.).

   6. (Physics) The quantity of matter which a body contains,
      irrespective of its bulk or volume.

   Note: Mass and weight are often used, in a general way, as
         interchangeable terms, since the weight of a body is
         proportional to its mass (under the same or equal
         gravitative forces), and the mass is usually
         ascertained from the weight. Yet the two ideas, mass
         and weight, are quite distinct. Mass is the quantity of
         matter in a body; weight is the comparative force with
         which it tends towards the center of the earth. A mass
         of sugar and a mass of lead are assumed to be equal
         when they show an equal weight by balancing each other
         in the scales.
