  OBSERVATIONS 
  ON 
  SULPHUROUS 
  ETHER, 
  

  

  To 
  the 
  hydrocarbon 
  of 
  Hennel 
  (4CH), 
  as 
  the 
  common 
  base 
  of 
  all 
  

   the 
  ethers, 
  excepting 
  those 
  lately 
  alleged 
  to 
  have 
  mytheline 
  for 
  a 
  base 
  ; 
  

   the 
  name 
  of 
  etherine 
  has 
  been 
  given 
  ; 
  so 
  that 
  the 
  heavy 
  oil 
  of 
  wine 
  

   may 
  be 
  called 
  the 
  sulphate 
  of 
  etherine 
  : 
  or, 
  according 
  to 
  the 
  formula 
  of 
  

   Serullas, 
  2SE-|-H, 
  it 
  is 
  a 
  hydrous 
  sulphate 
  of 
  etherine. 
  It 
  is, 
  in 
  fact, 
  

   the 
  only 
  compound 
  to 
  which 
  the 
  name 
  of 
  sulphuric 
  ether 
  can 
  be 
  ap- 
  

   plied 
  with 
  propriety. 
  The 
  yellow 
  liquid 
  out 
  of 
  which 
  it 
  is 
  procured, 
  

   as 
  above 
  stated, 
  may 
  be 
  designated 
  as 
  the 
  ethereal 
  sulphurous 
  sulphate 
  

   of 
  etherine. 
  

  

  Another 
  oil, 
  lighter 
  than 
  water, 
  resulting 
  from 
  the 
  distillation 
  of 
  the 
  

   ethereal 
  sulphurous 
  sulphate 
  of 
  etherine, 
  from 
  hydrate 
  of 
  lime, 
  or 
  

   from 
  potash, 
  is 
  described 
  by 
  Berzelius 
  as 
  oil 
  of 
  wine 
  exempt 
  from 
  

   sulphuric 
  acid. 
  Of 
  this 
  the 
  odour 
  is 
  represented 
  as 
  disagreeable 
  ; 
  and, 
  

   though 
  nothing 
  is 
  said 
  of 
  its 
  taste, 
  it 
  is 
  to 
  be 
  presumed 
  that 
  it 
  diners 
  

   from 
  the 
  heavy 
  oil 
  of 
  wine 
  in 
  this 
  respect, 
  as 
  well 
  as 
  in 
  its 
  odour 
  and 
  

   specific 
  gravity. 
  

  

  Thenard 
  alleges, 
  that 
  when 
  the 
  heavy 
  oil 
  of 
  wine 
  is 
  heated 
  with 
  

   water 
  for 
  some 
  time, 
  a 
  liquid 
  swims 
  on 
  the 
  water, 
  which, 
  if 
  refrige- 
  

   rated 
  by 
  ice, 
  will, 
  within 
  twenty-four 
  hours, 
  deposit 
  crystals. 
  The 
  

   mother 
  liquid 
  he 
  calls 
  light 
  oil 
  of 
  wine, 
  while 
  to 
  the 
  crystals 
  he 
  

   gives 
  the 
  name 
  of 
  concrete 
  oil 
  of 
  wine. 
  Hennel 
  mentions 
  his 
  having 
  

   obtained 
  a 
  similar 
  product 
  by 
  the 
  reaction 
  of 
  oil 
  of 
  wine 
  with 
  water, 
  

   or 
  an 
  aqueous 
  solution 
  of 
  potash 
  ; 
  and 
  treats 
  the 
  crystalline 
  matter 
  as 
  

   the 
  base 
  of 
  the 
  heavy 
  oil 
  of 
  wine, 
  deprived 
  of 
  its 
  acid 
  ; 
  or, 
  in 
  other 
  

   words, 
  as 
  his 
  "hydrocarbon 
  ;" 
  or, 
  as 
  above 
  mentioned, 
  etherine. 
  

  

  Considering 
  how 
  much 
  has 
  been 
  written 
  on 
  this 
  topic, 
  I 
  am 
  sur- 
  

   prised 
  that 
  I 
  have 
  met 
  with 
  no 
  statements 
  respecting 
  the 
  reaction 
  of 
  

   ammonia 
  with 
  the 
  above 
  mentioned 
  ethereal 
  sulphurous 
  sulphate 
  of 
  

   etherine. 
  

  

  Since 
  the 
  year 
  1818,1 
  have 
  been 
  accustomed 
  to 
  saturate 
  the 
  acid 
  in 
  

   that 
  liquid 
  by 
  ammonia. 
  The 
  residue, 
  being 
  rendered 
  very 
  fragrant, 
  

   and 
  entirely 
  freed 
  from 
  its 
  sulphurous 
  odour, 
  by 
  admixture 
  with 
  

   about 
  twenty-four 
  parts 
  of 
  alcohol, 
  was 
  found 
  to 
  constitute 
  an 
  ano- 
  

   dyne, 
  possessing 
  eminently 
  all 
  the 
  efficacy 
  of 
  that 
  so 
  long 
  distinguished 
  

   by 
  the 
  name 
  of 
  Hoffman. 
  When 
  the 
  residue, 
  remaining 
  after 
  satu-
