  on 
  the 
  Behaviour 
  of 
  the 
  

  

  before 
  and 
  after 
  the 
  observations 
  of 
  each 
  of 
  the 
  other 
  con- 
  

   densers. 
  Table 
  I. 
  is 
  obtained 
  in 
  this 
  way. 
  The 
  scheme 
  

   adopted 
  limited 
  all 
  observations 
  to 
  an 
  interval 
  of 
  5 
  minutes. 
  

   Readings, 
  s 
  } 
  at 
  the 
  electrometer 
  were 
  taken 
  per 
  minute, 
  and 
  

  

  by 
  dividing 
  them 
  into 
  iwo 
  parts 
  the 
  rates 
  Sa/Bt 
  were 
  obtained 
  

   linearly 
  from 
  data 
  3 
  minutes 
  apart. 
  The 
  table 
  also 
  contains 
  

   other 
  constants 
  to 
  be 
  discussed 
  below. 
  The 
  first 
  measure- 
  

   ment 
  is 
  given 
  in 
  full 
  as 
  an 
  example 
  of 
  the 
  method, 
  the 
  others 
  

   are 
  abbreviated.
