  The 
  rate 
  q 
  at 
  which 
  the 
  gas 
  is 
  supplied 
  to 
  the 
  tube 
  is 
  *85 
  

   cubic 
  centimetres 
  per 
  second; 
  so 
  that 
  (p 
  — 
  /o) 
  x 
  51 
  is 
  the 
  

   charge 
  given 
  to 
  the 
  tube 
  per 
  minute 
  as 
  the 
  gas 
  passes 
  through 
  

  

  it 
  and 
  is 
  proportional 
  to 
  w

  V 
  is 
  proportional

  where 
  V, 
  the 
  volume 
  of 
  the 
  tubs, 
  is 
  60*4 
  cubic 
  centi- 
  

   metres. 
  

  

  Thus 
  we 
  get

  The 
  ratio 
  — 
  — 
  - 
  was 
  also 
  found 
  to 
  increase 
  when 
  the 
  

  

  P 
  

  

  current 
  through 
  the 
  electrolyte 
  diminished, 
  thus 
  showing 
  

  

  that 
  the 
  ratio 
  depended 
  upon 
  the 
  rate 
  at 
  which 
  the 
  gas 
  is 
  

   supplied 
  to 
  the 
  tube. 
  Another 
  tube 
  of 
  equal 
  length 
  and 
  1*12 
  

   centimetres 
  in 
  diameter 
  was 
  examined 
  by 
  similar 
  methods, 
  

   and 
  it 
  was 
  found 
  to 
  have 
  a 
  far 
  less 
  discharging-rpower 
  than 
  

   the 
  larger 
  tube, 
  so 
  that, 
  when 
  the 
  supply 
  q 
  and 
  density 
  p 
  

   are 
  given, 
  the 
  smaller 
  the 
  bore 
  of 
  the 
  tubing 
  that 
  is 
  used 
  to 
  

   convey 
  the 
  gas 
  from 
  one 
  vessel 
  to 
  another, 
  the 
  less 
  will 
  be 
  

   the 
  loss 
  of 
  the 
  charge. 
  The 
  above 
  results 
  showing 
  the 
  

  

  dependence 
  of 
  — 
  — 
  - 
  on 
  p 
  are 
  important,
