  The 
  above 
  table 
  is 
  very 
  instructive. 
  It 
  shows 
  in 
  the 
  first 
  

   place 
  that 
  the 
  volumes 
  of 
  benzene 
  and 
  hexamethylene 
  are 
  

   very 
  nearly 
  in 
  the 
  ratio 
  30 
  : 
  36 
  under 
  conditions 
  of 
  corre- 
  

   sponding 
  pressure. 
  This 
  ratio 
  is 
  similar 
  to 
  that 
  between 
  the 
  

   valency 
  numbers. 
  It 
  is 
  thus 
  seen 
  that 
  the 
  ratio 
  of 
  the 
  

   volumes 
  of 
  carbon 
  and 
  hydrogen 
  is 
  still 
  as 
  4 
  : 
  1, 
  although 
  

   the 
  series 
  is 
  quite 
  different 
  to 
  that 
  of 
  the 
  paraffin 
  hydro- 
  

   carbons. 
  Such 
  a 
  regularity 
  is 
  most 
  remarkable, 
  and 
  the 
  

   probability 
  is 
  very 
  great 
  that 
  the 
  additive 
  relations 
  found 
  to 
  

   exist 
  under 
  corresponding 
  conditions 
  will 
  ultimately 
  be 
  found 
  

   to 
  be 
  connected 
  with 
  a 
  kind 
  of 
  liquid 
  structure 
  which 
  has 
  

   been 
  little 
  suspected.
