  Mr. 
  Grervaise 
  Le 
  Bas 
  

  

  observed 
  by 
  Horstmann, 
  which 
  have 
  long 
  been 
  known, 
  now 
  

   find 
  their 
  place 
  in 
  a 
  scheme 
  of 
  molecular 
  volumes. 
  

  

  The 
  data 
  referring 
  to 
  unsaturated 
  compounds 
  are 
  far 
  too 
  

   incomplete 
  both 
  as 
  regards 
  the 
  number 
  and 
  variety 
  of 
  sub- 
  

   stances 
  observed 
  and 
  as 
  regards 
  the 
  ranges 
  of 
  temperatures 
  

   to 
  attempt 
  to 
  account 
  for 
  the 
  different 
  results 
  respecting 
  the 
  

   effect 
  of 
  unsaturation 
  on 
  molecular 
  volumes 
  which 
  have 
  been 
  

   obtained 
  at 
  the 
  melting- 
  and 
  boiling-points 
  respectively. 
  

  

  The 
  following 
  table 
  shows 
  that 
  at 
  the 
  boiling-point 
  the 
  

   normal 
  paraffins 
  and 
  the 
  unsaturated 
  series 
  of 
  hydrocarbons 
  

   fall 
  into 
  one 
  scheme 
  owing 
  to 
  the 
  fact 
  that 
  carbon 
  and 
  

   hydrogen 
  respectively 
  possess 
  approximately 
  the 
  same 
  volumes 
  

   in 
  each. 
  This 
  is 
  also 
  true 
  of 
  hydrocarbon 
  residues 
  saturated 
  

   and 
  unsaturated.
