  In 
  the 
  table, 
  the 
  first 
  column 
  gives 
  the 
  negative 
  potentials 
  

   applied 
  to 
  the 
  gauze 
  cage 
  ; 
  the 
  second, 
  third, 
  fourth, 
  and 
  fifth 
  

   give 
  the 
  currents 
  (in 
  arbitrary 
  units) 
  observed 
  at 
  3, 
  22, 
  46, 
  and 
  

   66 
  hours, 
  respectively, 
  after 
  the 
  application 
  of 
  the 
  liquid 
  air; 
  

   the 
  remaining 
  columns 
  give 
  the 
  differences 
  between 
  these 
  

   currents.
