  Decomposition 
  

  

  By 
  altering 
  the 
  temperature 
  of 
  one 
  of 
  the 
  condensers 
  or 
  by 
  

   changing 
  the 
  speed 
  of 
  one 
  of 
  the 
  pumps, 
  the 
  current 
  of 
  water- 
  

   vapour 
  passing 
  through 
  A 
  could 
  be 
  made 
  either 
  faster 
  or 
  

   slower 
  than 
  that 
  passing 
  through 
  C. 
  

  

  The 
  amount 
  of 
  separation 
  of 
  oxygen 
  and 
  hydrogen 
  ob- 
  

   tained 
  with 
  this 
  apparatus 
  was 
  found 
  to 
  depend 
  on 
  the 
  dif- 
  

   ference 
  between 
  the 
  velocities 
  of 
  the 
  two 
  streams. 
  When 
  

   the 
  more 
  rapid 
  current 
  passed 
  through 
  the 
  bulb 
  containing 
  

   the 
  cathode, 
  an 
  excess 
  of 
  hydrogen 
  was 
  obtained 
  at 
  that 
  pole, 
  

   while 
  oxygen 
  appeared 
  at 
  the 
  anode 
  ; 
  but 
  if 
  the 
  faster 
  stream 
  

   passed 
  through 
  the 
  anode 
  bulb, 
  the 
  poles 
  at 
  which 
  the 
  

   excesses 
  of 
  oxygen 
  and 
  hydrogen 
  were 
  collected 
  were 
  

   reversed.

  Further, 
  the 
  amount 
  of 
  the 
  excesses 
  of 
  oxygen 
  and 
  

   hydrogen 
  was 
  much 
  less 
  when 
  the

  rapid 
  stream
