  The 
  following 
  data 
  are 
  abbreviated 
  by 
  omitting 
  the 
  individual 
  deflexions 
  

   s 
  and 
  times

  Curiously, 
  K6 
  showed 
  a 
  linear 
  diminution 
  of 
  potential 
  or 
  

   constant 
  current, 
  while 
  in 
  other 
  cases 
  the 
  currents 
  usually 
  

   fell 
  off. 
  Again, 
  the 
  values 
  of 
  Bs/8t 
  for 
  K6 
  in 
  the 
  lapse 
  of 
  

   time, 
  fig. 
  4, 
  first 
  show 
  a 
  decrease 
  ('0049 
  to 
  *0039) 
  , 
  thereafter 
  

   a 
  constant 
  variation, 
  finally 
  actually 
  an 
  increase 
  ('0039 
  to 
  

   •0043). 
  Hence 
  the 
  factors 
  which 
  determine 
  the 
  activity 
  of 
  

   phosphorus 
  are 
  extremely 
  complicated. 
  Moreover, 
  if 
  the 
  

   observations 
  for 
  the 
  other 
  condensers 
  are 
  corrected 
  by 
  the 
  

   results 
  tor 
  K6, 
  by 
  putting 
  the 
  current 
  for 
  the 
  latter 
  '0050 
  

   throughout, 
  the 
  new 
  values 
  show 
  worse 
  agreement 
  than 
  the 
  

   original 
  values. 
  It 
  follows 
  from 
  this 
  that 
  the 
  method 
  of 
  

   correction 
  proposed 
  is 
  not 
  available, 
  and 
  that 
  the 
  discrepancies 
  

   to 
  be 
  eliminated 
  are 
  not 
  regular 
  but 
  incidental 
  fluctuations. 
  

   Moreover, 
  the 
  data 
  of 
  this 
  table 
  are 
  uniformly 
  smaller, 
  

   scarcely 
  \ 
  or 
  | 
  of 
  the 
  values 
  referred 
  to 
  in 
  §4. 
  They 
  are 
  

   insufficiently 
  definite 
  to 
  suggest 
  the 
  form 
  of 
  the 
  locus. 
  New 
  

   observations, 
  Table 
  II., 
  were 
  therefore 
  needed 
  and 
  were 
  made 
  

   in 
  the 
  same 
  way 
  as 
  the 
  results 
  given 
  in 
  Table 
  I. 
  The 
  con- 
  

   denser 
  was 
  slightly 
  modified, 
  consisting 
  in 
  this 
  case 
  of 
  a 
  

   sphere 
  of 
  wire 
  gauze 
  about 
  1

  diameter,
