              A symbol is a sign included in the idea which it
              represents, e. g., an actual part chosen to
              represent the whole, or a lower form or species used
              as the representative of a higher in the same kind.
                                                    --Coleridge.

           numerical expression which defines its position
           relatively to the assumed axes.
  
     3. (Theol.) An abstract or compendium of faith or doctrine; a
        creed, or a summary of the articles of religion.
  
     4. [Gr. ? contributions.] That which is thrown into a common

              come to pay their symbol in a war or in a plague.
                                                    --Jer. Taylor.

        element and consisting of the initial letter of the Latin

        (Natrium), {Fe} for iron (Ferrum), {Sn} for tin (Stannum),
        {Sb} for antimony (Stibium), etc. See the list of names
        and symbols under {Element}.
  
     Note: In pure and organic chemistry there are symbols not
           only for the elements, but also for their grouping in
           formulas, radicals, or residues, as evidenced by their
           composition, reactions, synthesis, etc. See the diagram
           of {Benzene nucleus}, under {Benzene}.
