  Observations 
  on 
  Sulphurous 
  Ether, 
  and 
  Sulphate 
  of 
  Etherine 
  (the 
  

   true 
  Sulphurous 
  Ether). 
  By 
  R. 
  Hare, 
  M. 
  D., 
  Professor 
  of 
  Chemistry 
  

   in 
  the 
  University 
  of 
  Pennsylvania. 
  

  

  It 
  is 
  known 
  that 
  when 
  two 
  parts, 
  by 
  weight, 
  of 
  sulphuric 
  acid 
  are 
  

   distilled 
  with 
  one 
  of 
  alcohol, 
  a 
  yellow 
  sulphurous 
  liquid 
  is 
  obtained. 
  

   Berzelius 
  alleges, 
  that 
  when 
  this 
  liquid 
  is 
  exposed 
  in 
  an 
  exhausted 
  re- 
  

   ceiver 
  over 
  sulphuric 
  acid 
  and 
  hydrate 
  of 
  potash, 
  an 
  oleaginous 
  liquid 
  

   remains, 
  which 
  he 
  designates 
  as 
  u 
  oil 
  of 
  wine 
  containing 
  sulphuric 
  acid, 
  

   or 
  heavy 
  oil 
  of 
  wine." 
  

  

  This 
  oil 
  is, 
  by 
  the 
  same 
  author, 
  described 
  as 
  being 
  heavier 
  than 
  

   water, 
  as 
  having 
  a 
  penetrating 
  aromatic 
  odour, 
  and 
  a 
  cool 
  pungent 
  

   taste, 
  resembling 
  that 
  of 
  peppermint. 
  It 
  is, 
  in 
  fact, 
  the 
  liquid 
  which 
  

   Hennel 
  first 
  analysed 
  as 
  oil 
  of 
  wine, 
  without, 
  at 
  the 
  same 
  time, 
  men- 
  

   tioning 
  the 
  process 
  by 
  which 
  it 
  was 
  procured. 
  No 
  doubt 
  the 
  differ- 
  

   ence 
  between 
  it 
  and 
  that 
  procured 
  by 
  Boullay 
  and 
  Dumas, 
  was, 
  in 
  some 
  

   degree, 
  the 
  cause 
  of 
  the 
  discordance 
  between 
  his 
  observation 
  and 
  theirs. 
  

   According 
  to 
  Hennel, 
  the 
  oil 
  of 
  wine 
  consists 
  of 
  an 
  atom 
  of 
  sulphuric 
  

   acid, 
  and 
  an 
  atom 
  of 
  hydrocarbon 
  :

  By 
  the 
  last 
  men- 
  

   tioned 
  appellation, 
  this 
  skilful 
  chemist 
  designates 
  a 
  compound 
  consist- 
  

   ing 
  of 
  four 
  atoms 
  of 
  carbon, 
  and 
  four 
  of 
  hydrogen. 
  

  

  Serullas 
  represents 
  the 
  oil 
  in 
  question 
  as 
  consisting 
  of 
  two 
  atoms 
  of 
  

   the 
  acid, 
  two 
  of 
  hydrocarbon 
  or 
  etherine, 
  and 
  one 
  of 
  water.
