  From 
  this 
  table 
  the 
  curves 
  C 
  D, 
  E 
  F 
  of 
  fig. 
  3 
  have 
  been 
  

   plotted. 
  I 
  have 
  called 
  ^A 
  the 
  " 
  dividing 
  factor." 
  

  

  It 
  will 
  be 
  noted 
  from 
  the 
  curve 
  C 
  D 
  (fig. 
  3) 
  that 
  the 
  amount 
  

   of 
  emanation 
  in 
  existence 
  increases 
  very 
  nearly 
  proportional 
  

   to 
  the 
  time 
  when 
  the 
  time 
  is 
  small, 
  but 
  that 
  there 
  is 
  a 
  slight 
  

   falling 
  off 
  due 
  to 
  the 
  decay 
  of 
  the 
  first 
  portions 
  produced. 
  

  

  We 
  see 
  from 
  Table 
  II. 
  and 
  fig. 
  3 
  that 
  in 
  2 
  hours

  amount
