  on 
  the 
  Behaviour 
  of 
  the 
  

  

  a 
  much 
  larger 
  piece 
  of 
  phosphorus 
  than 
  above. 
  The 
  larger 
  

   condenser 
  K 
  4 
  is 
  now 
  the 
  standard, 
  admitting 
  of 
  easier 
  ad- 
  

   justment. 
  The 
  constancy 
  of 
  the 
  ionizer 
  is 
  shown 
  in 
  fig. 
  4 
  

   (upper 
  curve 
  K 
  4), 
  displaced 
  in 
  ordinate, 
  for 
  convenience.

  In 
  Table 
  III. 
  the 
  ionizing 
  activity 
  of 
  phosphorus 
  is 
  ex- 
  

   hibited 
  when 
  the 
  condenser, 
  K 
  4, 
  is 
  left 
  quite 
  without 
  inter- 
  

   ference. 
  A 
  remarkable 
  rise 
  and 
  fall 
  is 
  as 
  usual 
  apparent, 
  

   without 
  discernable 
  cause 
  (fig. 
  4, 
  lower 
  curve). 
  After 
  this, 
  

   the 
  other 
  condensers 
  are 
  again 
  tested 
  with 
  the 
  object 
  of 
  

   securing 
  sufficient 
  data 
  to 
  at 
  least 
  roughly 
  suggest 
  the 
  form 
  

   of 
  the 
  locus. 
  

  

  Both 
  Tables 
  II. 
  and 
  III. 
  have 
  been 
  abbreviated 
  ; 
  the 
  results 
  

   of 
  interest 
  admit 
  of 
  graphic 
  representation, 
  as 
  will 
  be 
  explained 
  

   in 
  relation 
  to 
  figs. 
  3 
  and 
  5. 
  

  

  7. 
  In 
  view 
  of 
  the 
  fact 
  that 
  the 
  ionizing 
  potency 
  of 
  phos- 
  

   phorus 
  sometimes 
  increases 
  and 
  at 
  other 
  times 
  decreases, 
  as- 
  

   it 
  were 
  incidentally 
  and 
  subject 
  to 
  arbitrary 
  conditions* 
  not 
  

   made 
  out,

  have 
  in 
  fig. 
  5 
  summarized 
  the 
  uncorrected 
  values 
  

   of 
  the 
  initial 
  currents, 
  Bs/6t

  preferably 
  to 
  the 
  corrected 
  

  

  * 
  Work 
  still 
  in 
  progress 
  has 
  shown 
  me 
  that 
  the 
  variability 
  of 
  the 
  

   phosphorus 
  ionizer 
  is 
  related 
  to 
  the 
  hygrometric 
  conditions 
  under 
  which, 
  

   the 
  experiments 
  are 
  made. 
  Temperature 
  is 
  of 
  secondary 
  importance.
