  Celtium \Cel"ti*um\, n. [NL.] (Chem.)
     The first proposed name for a supposed new element of the
     rare-earth group, accompanying lutecium and scandium in the
     gadolinite earths. It is now considered identical to
     {Lutetium}. The proposed symbol was Ct (no period), but this
     name and symbol are no longer used.
