  Nickel, 
  

  

  The 
  thermionic 
  current 
  from 
  nickel 
  was 
  investigated 
  under 
  

  

  essentially 
  the 
  same 
  conditions 
  as 
  those 
  last 
  mentioned 
  in 
  

  

  connexion 
  with 
  tantalum. 
  The 
  ions 
  were 
  emitted 
  froni 
  a 
  

  

  nickel 
  strip 
  0*004 
  cm. 
  in 
  thickness.
