  Mr. 
  E. 
  Parr 
  Metcalfe 
  on 
  

  

  In 
  the 
  case 
  of 
  the 
  paraffins, 
  the 
  addition 
  of 
  (C 
  + 
  2H) 
  to 
  

   the 
  molecule 
  increases 
  the 
  molecular 
  ionization 
  by 
  a 
  mean 
  

   amount 
  '92. 
  If 
  we 
  deduct 
  '23 
  as 
  being 
  the 
  contribution 
  of 
  

   the 
  2H, 
  we 
  obtain 
  as 
  that 
  of 
  a 
  single 
  carbon 
  atom 
  '69.
