From The Collaborative International Dictionary of English v.0.48 :

  Hydrochloric \Hy`dro*chlo"ric\, a. [Hydro-, 2 + chloric: cf. F.
     hydrochlorique.] (Chem.)
     Pertaining to, or compounded of, chlorine and hydrogen gas;
     as, hydrochloric acid; chlorhydric.
     [1913 Webster]
  
     Hydrochloric acid (Chem.), hydrogen chloride; a colorless,
        corrosive gas, HCl, of pungent, suffocating odor. It is
        made in great quantities in the soda process, by the
        action of sulphuric acid on common salt. It has a great
        affinity for water, and the commercial article is a strong
        solution of the gas in water. It is a typical acid, and is
        an indispensable agent in commercial and general chemical
        work. Called also muriatic acid and chlorhydric acid.

  Ion \I"on\ ([imac]"[o^]n), n. [Gr. 'io`n, neut, of 'iw`n, p. pr.
     of 'ie`nai to go.]
     1. (Elec. Chem.) an atom or goup of atoms (radical) carrying
        an electrical charge. It is contrasted with neutral atoms
        or molecules, and free radicals. Certain compounds, such
        as sodium chloride, are composed of complementary ions in
        the solid (crystalline) as well as in solution. Others,
        notably acids such as hydrogen chloride, may occur as
        neutral molecules in the pure liquid or gas forms, and
        ionize almost completely in dilute aqueous solutions. In
        solutions (as in water) ions are frequently bound
        non-covalently with the molecules of solvent, and in that
        case are said to be solvated. According to the
        electrolytic dissociation theory, the molecules of
        electrolytes are divided into ions by water and other
        solvents. An ion consists of one or more atoms and carries
        one unit charges of electricity, 3.4 x 10^{-10
        electrostatic units, or a multiple of this. Those which
        are positively electrified (hydrogen and the metals) are
        called cations; negative ions (hydroxyl and acidic atoms
        or groups) are called anions.
  
     Note: Thus, hydrochloric acid ({HCl) dissociates, in aqueous
           solution, into the hydrogen ion, H+, and the chlorine
           ion, Cl-; ferric nitrate, Fe(NO3)3, yields the
           ferric ion, Fe+++, and nitrate ions, NO3-, NO3-,
           NO3-. When a solution containing ions is made part of
           an electric circuit, the cations move toward the
           cathode, the anions toward the anode. This movement is
           called migration, and the velocity of it differs for
           different kinds of ions. If the electromotive force is
           sufficient, electrolysis ensues: cations give up their
           charge at the cathode and separate in metallic form or
           decompose water, forming hydrogen and alkali;
           similarly, at the anode the element of the anion
           separates, or the metal of the anode is dissolved, or
           decomposition occurs. Aluminum and chlorine are
           elements prepared predominantly by such electrolysis,
           and depends on dissolving compounds in a solvent where
           the element forms ions. Electrolysis is also used in
           refining other metals, such as copper and silver. Cf.
           Anion, Cation.
           [Webster 1913 Suppl.]
  
     2. One of the small electrified particles into which the
        molecules of a gas are broken up under the action of the
        electric current, of ultraviolet and certain other rays,
        and of high temperatures. To the properties and behavior
        of ions the phenomena of the electric discharge through
        rarefied gases and many other important effects are
        ascribed. At low pressures the negative ions appear to be
        electrons; the positive ions, atoms minus an electron. At
        ordinary pressures each ion seems to include also a number
        of attached molecules. Ions may be formed in a gas in
        various ways.

  Muriatic \Mu`ri*at"ic\, a. [L. muriaticus pickled, from muria
     brine: cf. F. muriatique.] (Chem.)
     Of, pertaining to, or obtained from, sea salt, or from
     chlorine, one of the constituents of sea salt; hydrochloric.

            [1913 Webster]
  
     Note: Type are mostly made by casting type metal in a mold,
           though some of the larger sizes are made from maple,
           mahogany, or boxwood. In the cut, a is the body; b, the
           face, or part from which the impression is taken; c,
           the shoulder, or top of the body; d, the nick
           (sometimes two or more are made), designed to assist
           the compositor in distinguishing the bottom of the face
           from t`e top; e, the groove made in the process of
           finishing, -- each type as cast having attached to the
           bottom of the body a jet, or small piece of metal
           (formed by the surplus metal poured into the mold),
           which, when broken off, leaves a roughness that
           requires to be removed. The fine lines at the top and
           bottom of a letter are technically called ceriphs, and
           when part of the face projects over the body, as in the
           letter f, the projection is called a kern.
           [1913 Webster] The type which compose an ordinary book
           font consist of Roman CAPITALS, small capitals, and
           lower-case letters, and Italic CAPITALS and lower-case
           letters, with accompanying figures, points, and
           reference marks, -- in all about two hundred
           characters. Including the various modern styles of
           fancy type, some three or four hundred varieties of
           face are made. Besides the ordinary Roman and Italic,
           some of the most important of the varieties are 
           [1913 Webster] Old English. Black Letter. Old Style.
           French Elzevir. Boldface. Antique. Clarendon. Gothic.
           Typewriter. Script.
           [1913 Webster] The smallest body in common use is
           diamond; then follow in order of size, pearl, agate,
           nonpareil, minion, brevier, bourgeois (or two-line
           diamond), long primer (or two-line pearl), small pica
           (or two-line agate), pica (or two-line nonpareil),
           English (or two-line minion), Columbian (or two-line
           brevier), great primer (or two-line bourgeois), paragon
           (or two-line long primer), double small pica (or
           two-line small pica), double pica (or two-line pica),
           double English (or two-line English), double great
           primer (or two-line great primer), double paragon (or
           two-line paragon), canon (or two-line double pica).
           Above this, the sizes are called five-line pica,
           six-line pica, seven-line pica, and so on, being made
           mostly of wood. The following alphabets show the
           different sizes up to great primer.

           [1913 Webster] The foregoing account is conformed to
           the designations made use of by American type founders,
           but is substantially correct for England. Agate,
           however, is called ruby, in England, where, also, a
           size intermediate between nonpareil and minion is
           employed, called emerald.
           [1913 Webster]
  
     Point system of type bodies (Type Founding), a system
        adopted by the type founders of the United States by which
        the various sizes of type have been so modified and
        changed that each size bears an exact proportional
        relation to every other size. The system is a modification
        of a French system, and is based on the pica body. This
        pica body is divided into twelfths, which are termed
        "points," and every type body consist of a given number of
        these points. Many of the type founders indicate the new
        sizes of type by the number of points, and the old names
        are gradually being done away with. By the point system
        type founders cast type of a uniform size and height,
        whereas formerly fonts of pica or other type made by
        different founders would often vary slightly so that they
        could not be used together. There are no type in actual
        use corresponding to the smaller theoretical sizes of the
        point system. In some cases, as in that of ruby, the term
        used designates a different size from that heretofore so
        called.
