  A 
  determination 
  of 
  the 
  molecular 
  volume 
  of 
  a 
  compound 
  

   at 
  the 
  boiling-point 
  enables 
  us 
  not 
  only 
  to 
  show 
  that 
  it 
  is 
  

   cyclic, 
  but 
  also, 
  to 
  some 
  extent, 
  the 
  nature 
  of 
  the 
  ring 
  inde- 
  

   pendently 
  of 
  whether 
  it 
  is 
  aliphatic 
  or 
  aromatic. 
  

  

  If 
  the 
  case 
  of 
  carvene 
  C 
  10 
  H 
  16 
  be 
  considered, 
  it 
  will 
  be 
  

   found 
  to 
  be 
  subject 
  to 
  a 
  contraction 
  similar 
  to 
  that 
  character- 
  

   istic 
  of 
  benzene 
  compounds, 
  and 
  thus 
  the 
  ring 
  is 
  shown 
  not 
  

   double. 
  

  

  M.V. 
  of 
  carvene 
  C 
  10 
  H 
  16 
  at 
  the 
  B.P. 
  is 
  190'3 
  ; 
  W 
  =

   Volume 
  of 
  the 
  complex 
  Ci 
  H

  in 
  the 
  fatty 
  series 
  is 
  

  

  = 
  58x3-7

  contraction 
  —

  The 
  following 
  table 
  includes 
  two 
  isomeric 
  ring-compounds 
  

   of 
  high 
  complexity, 
  namely 
  anthracene 
  and 
  phenanthrene.
