﻿AND 
  SULPHATE 
  OF 
  ETHERINE. 
  349 
  

  

  ration 
  with 
  ammonia, 
  was 
  distilled 
  in 
  a 
  water 
  bath, 
  ether 
  came 
  over, 
  

   and 
  left 
  an 
  oil 
  which 
  I 
  was 
  accustomed 
  to 
  consider 
  as 
  the 
  oil 
  of 
  wine. 
  

  

  I 
  had 
  observed 
  that, 
  in 
  the 
  process 
  above 
  mentioned, 
  there 
  was 
  a 
  

   striking 
  evolution 
  of 
  vapour, 
  which 
  seemed 
  irreconcilable 
  with 
  the 
  

   received 
  opinion 
  of 
  the 
  re-agents 
  employed. 
  Since 
  the 
  affinity 
  be- 
  

   tween 
  the 
  ammonia 
  and 
  sulphurous 
  acid 
  is 
  energetic, 
  it 
  did 
  not 
  ap- 
  

   pear 
  to 
  be 
  reasonable 
  that 
  a 
  copious 
  escape 
  of 
  the 
  one 
  should 
  be 
  caused 
  

   by 
  its 
  admixture 
  with 
  the 
  other; 
  and 
  it 
  was 
  no 
  less 
  improbable 
  that 
  

   the 
  vaporization 
  of 
  hydric 
  ether, 
  in 
  its 
  natural 
  state, 
  could 
  take 
  place 
  

   at 
  temperatures 
  so 
  much 
  below 
  its 
  boiling 
  point 
  as 
  those 
  at 
  which 
  this 
  

   phenomenon 
  was 
  noticed. 
  In 
  order 
  to 
  ascertain 
  the 
  truth, 
  I 
  luted 
  a 
  

   funnel, 
  furnished 
  with 
  a 
  glass 
  cock 
  and 
  an 
  air 
  tight 
  stopple, 
  into 
  the 
  

   tubulure 
  of 
  a 
  retort, 
  of 
  which 
  the 
  beak 
  was 
  so 
  recurved 
  downwards 
  as 
  

   to 
  enter 
  and 
  be 
  luted 
  into 
  the 
  tubulure 
  of 
  another 
  retort. 
  The 
  beak 
  

   of 
  the 
  latter 
  passed 
  under 
  a 
  bell 
  over 
  water. 
  

  

  Both 
  retorts 
  were 
  about 
  half 
  full 
  of 
  liquid 
  ammonia, 
  and 
  surrounded 
  

   with 
  ice. 
  The 
  apparatus 
  being 
  thus 
  arranged, 
  about 
  a 
  thousand 
  grains 
  

   of 
  the 
  ethereal 
  sulphurous 
  sulphate 
  of 
  etherine 
  were 
  poured 
  into 
  the 
  

   funnel, 
  and 
  thence 
  gradually 
  allowed 
  to 
  descend 
  into 
  the 
  ammonia 
  in 
  

   the 
  first 
  retort. 
  Notwithstanding 
  the 
  refrigeration, 
  much 
  heat 
  was 
  

   perceptible, 
  and 
  a 
  copious 
  evolution 
  of 
  vapour, 
  which, 
  passing 
  into 
  the 
  

   second 
  retort, 
  was 
  there 
  absorbed 
  or 
  condensed, 
  none 
  being 
  observed 
  

   to 
  reach 
  the 
  bell 
  glass. 
  At 
  the 
  close 
  of 
  the 
  operation, 
  hydric 
  ether, 
  

   holding 
  oil 
  of 
  wine 
  in 
  solution, 
  floated 
  upon 
  the 
  ammonia 
  in 
  the 
  first 
  

   retort, 
  and 
  pure 
  ether, 
  of 
  the 
  same 
  kind, 
  floated 
  on 
  the 
  ammonia 
  in 
  

   the 
  second. 
  

  

  The 
  ammonia 
  in 
  both 
  retorts 
  gave 
  indications 
  of 
  the 
  presence 
  of 
  sul- 
  

   phurous 
  acid, 
  on 
  the 
  addition 
  of 
  sulphuric 
  acid. 
  From 
  these 
  results, 
  

   I 
  inferred 
  that 
  a 
  chemical 
  compound 
  of 
  sulphurous 
  acid 
  and 
  hydric 
  

   ether 
  formed 
  the 
  principal 
  portion 
  of 
  the 
  yellow 
  liquid, 
  and 
  might 
  be 
  

   separated 
  by 
  distillation. 
  Accordingly, 
  by 
  means 
  of 
  retorts 
  arranged 
  

   and 
  refrigerated 
  as 
  above 
  described, 
  I 
  procured 
  a 
  portion 
  of 
  sulphu- 
  

   rous 
  ether, 
  which 
  boiled 
  at 
  44°, 
  and 
  which, 
  when 
  agitated 
  with 
  am- 
  

   monia 
  in 
  a 
  bottle, 
  produced 
  so 
  much 
  heat 
  and 
  consequent 
  vapour, 
  as 
  to 
  

   expel 
  the 
  whole 
  contents 
  in 
  opposition 
  to 
  the 
  pressure 
  of 
  my 
  thumb. 
  

   By 
  employing 
  the 
  same 
  distillatory 
  apparatus,!
