  The 
  above 
  results 
  show 
  in 
  the 
  first 
  place 
  that 
  the 
  ratio 
  

   V/V 
  K 
  for 
  C 
  6 
  H 
  12 
  is 
  somewhat 
  larger 
  than 
  that 
  for 
  C 
  6 
  H 
  6 
  . 
  

   This 
  is 
  also 
  true 
  oE 
  the 
  ratios 
  V/W. 
  

  

  Secondly, 
  the 
  ratio 
  V'/V, 
  which 
  gives 
  the 
  volume 
  of 
  hexa- 
  

   methylene 
  relative 
  to 
  benzene, 
  is 
  very 
  nearly 
  equal 
  to 
  the 
  

   quotient 
  of 
  their 
  respective 
  valency 
  numbers. 
  

  

  Table 
  XXV. 
  gives 
  the 
  volumes 
  of 
  the 
  compounds 
  under 
  

   conditions 
  of 
  corresponding 
  pressure, 
  but 
  owing 
  to 
  the 
  fact 
  

   that 
  the 
  values 
  T/T 
  K 
  are 
  nearly 
  the 
  same 
  in 
  the 
  two 
  cases, 
  a 
  

   special 
  investigation 
  of 
  the 
  volume 
  relations 
  of 
  benzene 
  and 
  

   hexamethylene 
  at 
  corresponding 
  temperatures 
  is 
  unnecessary.
