﻿AND 
  SULPHATE 
  OF 
  ETHERINE.

  employed 
  in 
  the 
  process 
  for 
  generating 
  hydric 
  ether, 
  a 
  series 
  of 
  

   tubulated 
  retorts, 
  of 
  which 
  the 
  beaks 
  were 
  recurved 
  downwards 
  

   in 
  such 
  a 
  manner 
  that 
  the 
  beak 
  of 
  the 
  first 
  communicated 
  with 
  

   a 
  perpendicular 
  tube, 
  passing 
  through 
  an 
  open-necked 
  cylindrical 
  

   receiver, 
  so 
  as 
  to 
  enter 
  the 
  tubulure 
  of 
  the 
  second 
  retort, 
  of 
  which 
  the 
  

   beak 
  was 
  in 
  like 
  manner 
  inserted 
  into 
  a 
  tube 
  passing 
  through 
  a 
  receiver 
  

   in 
  a 
  third 
  retort, 
  and 
  this 
  communicated 
  in 
  like 
  manner 
  with 
  a 
  fourth 
  

   retort. 
  The 
  second, 
  third 
  and 
  fourth 
  retorts, 
  and 
  the 
  tubes 
  entering 
  

   them, 
  were 
  all 
  refrigerated, 
  the 
  first 
  with 
  ice, 
  the 
  second 
  with 
  ice 
  and 
  

   salt, 
  and 
  the 
  third 
  with 
  ice 
  and 
  chloride 
  of 
  calcium. 
  

  

  By 
  these 
  means, 
  on 
  subjecting 
  to 
  distillation 
  in 
  the 
  first 
  retort 
  48 
  

   ounces 
  of 
  alcohol 
  of 
  830, 
  and 
  a 
  like 
  weight 
  of 
  sulphuric 
  acid, 
  besides 
  

   the 
  ethereal 
  sulphurous 
  sulphate 
  of 
  etherine 
  usually 
  resulting 
  from 
  the 
  

   process, 
  and 
  condensing 
  in 
  the 
  first 
  receiver, 
  it 
  was 
  found 
  that 
  in 
  the 
  

   other 
  retorts 
  severally, 
  there 
  were 
  liquids 
  of 
  various 
  degrees 
  of 
  volati- 
  

   lity. 
  That 
  in 
  the 
  last 
  boiled 
  at 
  28°, 
  but 
  the 
  boiling 
  points 
  rose 
  gradu- 
  

   ally 
  as 
  the 
  quantity 
  of 
  the 
  residual 
  liquid 
  diminished. 
  

  

  In 
  order 
  to 
  ascertain 
  the 
  nature 
  of 
  the 
  sulph-acids 
  abstracted 
  

   from 
  the 
  ethereal 
  sulphurous 
  sulphate 
  of 
  etherine 
  by 
  the 
  ammonia 
  

   employed, 
  chloride 
  of 
  barium 
  was 
  added 
  in 
  excess 
  to 
  the 
  resulting 
  am- 
  

   moniacal 
  solution, 
  until 
  no 
  further 
  precipitate 
  would 
  ensue. 
  The 
  

   liquid 
  having 
  been 
  rendered 
  quite 
  clear 
  by 
  filtration, 
  soon 
  became 
  

   milky. 
  By 
  evaporation 
  to 
  dryness, 
  and 
  exposure 
  to 
  a 
  red 
  heat, 
  a 
  

   residuum 
  was 
  obtained 
  which 
  proved 
  partially 
  insoluble 
  in 
  chlorohydric 
  

   acid, 
  and 
  by 
  ignition 
  with 
  charcoal, 
  yielded 
  sulphide 
  of 
  barium. 
  It 
  

   appears, 
  therefore, 
  that 
  a 
  hyposulphate 
  of 
  barytes 
  existed 
  in 
  the 
  liquid 
  

   after 
  it 
  was 
  filtered 
  ; 
  as 
  I 
  believe 
  that 
  the 
  hyposulphuric 
  acid 
  is 
  the 
  only 
  

   oxacid 
  of 
  sulphur 
  which 
  is 
  capable 
  of 
  forming 
  with 
  barytes 
  a 
  soluble 
  

   compound, 
  susceptible, 
  by 
  access 
  of 
  oxygen, 
  of 
  being 
  converted 
  into 
  an 
  

   insoluble 
  sulphate, 
  and 
  precipitating 
  in 
  consequence. 
  

  

  It 
  must 
  be 
  evident 
  from 
  the 
  facts 
  which 
  I 
  have 
  narrated, 
  that 
  the 
  

   yellow 
  liquid 
  obtained 
  by 
  distilling 
  equal 
  measures 
  of 
  sulphuric 
  acid 
  

   and 
  alcohol, 
  consists 
  of 
  oil 
  of 
  wine 
  held 
  in 
  solution 
  by 
  sulphurous 
  

   ether, 
  composed 
  of 
  nearly 
  equal 
  volumes 
  or 
  weights 
  of 
  its 
  ingredients; 
  

   also, 
  that 
  the 
  affinity 
  between 
  the 
  ether 
  and 
  the 
  acid 
  is 
  analogous 
  to 
  

   that 
  which 
  exists 
  between 
  alcohol 
  and 
  water.
