  In 
  all 
  the 
  above 
  readings 
  the 
  current 
  was 
  not 
  kept 
  on 
  

   longer 
  than 
  was 
  necessary 
  to 
  obtain 
  a 
  balance, 
  so 
  as 
  to 
  avoid 
  

   changes 
  in 
  the 
  liquid 
  which 
  might 
  be 
  produced 
  by 
  the 
  

   passage 
  of 
  the 
  current, 
  especially 
  in 
  the 
  case 
  of 
  the 
  thinnest 
  

   layers 
  of 
  dilute 
  solutions, 
  where 
  the 
  resistance 
  was 
  small. 
  

   With 
  aniline 
  quickness 
  was 
  very 
  necessary 
  : 
  for, 
  as 
  was 
  

   found 
  previously, 
  its 
  conductivity 
  is 
  altered 
  very 
  much 
  by 
  

   the 
  passage 
  of 
  the 
  current.
