  The  name  given  by  Mendelejeff  in  accordance  with  the  periodic 
  law,  and  by  prediction,  to  a  hypothetical  element  then 
  unknown,  but  since  discovered  and  named  {scandium};  --  so 
  called  because  it  was  a  missing  analogue  of  the  boron  group 
  See  {Scandium}.
