        which forms rivers, lakes, seas, etc. "We will drink

     Note: Pure water consists of hydrogen and oxygen, {H2O}, and
           is a colorless, odorless, tasteless, transparent
           liquid, which is very slightly compressible. At its
           maximum density, 39[deg] Fahr. or 4[deg] C., it is the
           standard for specific gravities, one cubic centimeter
           weighing one gram. It freezes at 32[deg] Fahr. or
           0[deg] C. and boils at 212[deg] Fahr. or 100[deg] C.
           (see {Ice}, {Steam}). It is the most important natural
           solvent, and is frequently impregnated with foreign
           matter which is mostly removed by distillation; hence,
           rain water is nearly pure. It is an important
           ingredient in the tissue of animals and plants, the
           human body containing about two thirds its weight of
           water.
           [1913 Webster]
  
     2. A body of water, standing or flowing; a lake, river, or
        other collection of water.

        volatile substance; as, ammonia water. --U. S. Pharm.
        [1913 Webster]
  
     5. The limpidity and luster of a precious stone, especially a
        diamond; as, a diamond of the first water, that is,

        that is, of the first excellence.
        [1913 Webster]
  
     6. A wavy, lustrous pattern or decoration such as is imparted
        to linen, silk, metals, etc. See {Water}, v. t., 3,

     7. An addition to the shares representing the capital of a
        stock company so that the aggregate par value of the

        [1913 Webster]
  
     Note: Water is often used adjectively and in the formation of
           many self-explaining compounds; as, water drainage;
           water gauge, or water-gauge; waterfowl, water-fowl, or
           water fowl; water-beaten; water-borne, water-circled,
           water-girdled, water-rocked, etc.

     {Hard water}. See under {Hard}.
  
     {Inch of water}, a unit of measure of quantity of water,
        being the quantity which will flow through an orifice one
        inch square, or a circular orifice one inch in diameter,
        in a vertical surface, under a stated constant head; also
        called {miner's inch}, and {water inch}. The shape of the
        orifice and the head vary in different localities. In the
        Western United States, for hydraulic mining, the standard
        aperture is square and the head from 4 to 9 inches above
        its center. In Europe, for experimental hydraulics, the
        orifice is usually round and the head from 1/2 of an inch
        to 1 inch above its top.
  
     {Mineral water}, waters which are so impregnated with foreign

     {To make water}.
        (a) To pass urine. --Swift.
        (b) (Naut.) To admit water; to leak.
  
     {Water of crystallization} (Chem.), the water combined with
        many salts in their crystalline form. This water is
        loosely, but, nevertheless, chemically, combined, for it
        is held in fixed and definite amount for each substance
        containing it. Thus, while pure copper sulphate, {CuSO4},
        is a white amorphous substance, blue vitriol, the
        crystallized form, {CuSO4.5H2O}, contains five molecules
        of water of crystallization.
  
     {Water on the brain} (Med.), hydrocephalus.
  
     {Water on the chest} (Med.), hydrothorax.
        [1913 Webster]
  
     Note: Other phrases, in which water occurs as the first
           element, will be found in alphabetical order in the
           Vocabulary.
