  Holmium \Hol"mi*um\, n. [NL., from Stockholm.] (Chem.)
     A rare element of atomic number 67 said to be contained in
     gadolinite. Chemical symbol Ho. Atomic weight 164.93. Valence
     +3. It was detected by spectral absorption bands in 1878 by
     the Delafontaine and Soret, who called it "Element X". Later
     the Swedish chemist Cleve independently discovered it in


     erbia, and named it after his native city Stockholm. The
     first preparation of pure Holmia, the yellow oxide, was not
     made until 1911. --HCP61 -- {Hol"mic}, a.
