  For 
  very 
  small 
  currents 
  the 
  discharge 
  throuo:h 
  HI 
  

   could 
  be 
  kept 
  fairly 
  constant, 
  and 
  gave 
  under 
  these 
  conditions 
  

   an 
  nnstriated 
  column 
  with 
  feeble 
  blue 
  light. 
  With 
  decrease 
  

   of 
  resistance 
  the 
  larger 
  current 
  would 
  not 
  keep 
  constant, 
  but 
  

   increased 
  gradually, 
  the 
  pressure 
  diminished 
  considerably, 
  

   and 
  the 
  discharge 
  became 
  striated. 
  The 
  potential

   for 
  different
