﻿AND 
  SULPHATE 
  OF 
  ETHERINE.

  time 
  over 
  liquid 
  ammonia, 
  yielded 
  only 
  seven-eighths 
  of 
  a 
  grain 
  of 
  sul- 
  

   phate. 
  

  

  About 
  a 
  drachm 
  of 
  Hennel's 
  oil 
  of 
  wine 
  was 
  subjected 
  to 
  distillation 
  

   with 
  strong 
  liquid 
  ammonia 
  ; 
  fourteen 
  and 
  a 
  half 
  grains 
  came 
  over, 
  re- 
  

   taining 
  the 
  appropriate 
  fragrance 
  and 
  flavour. 
  This 
  yielded, 
  by 
  the 
  

   process 
  above 
  described, 
  only 
  two 
  grains 
  of 
  sulphate 
  of 
  barytes. 
  After 
  

   all 
  the 
  water 
  and 
  ammonia 
  had 
  distilled, 
  the 
  receiver 
  was 
  changed, 
  and 
  

   fourteen 
  grains 
  of 
  oil, 
  devoid 
  of 
  the 
  fragrance 
  and 
  flavour 
  of 
  the 
  oil 
  of 
  

   wine, 
  were 
  obtained. 
  This 
  yielded 
  one 
  and 
  one-eighth 
  grains 
  of 
  sulphate. 
  

   A 
  carbonaceous 
  mass, 
  replete 
  with 
  sulphuric 
  acid, 
  remained 
  in 
  the 
  

   retort. 
  

  

  Hennel 
  states 
  that 
  when 
  oil 
  of 
  wine 
  was 
  heated 
  in 
  a 
  solution 
  of 
  potash, 
  

   an 
  oil 
  was 
  liberated 
  which 
  floated 
  upon 
  water, 
  having 
  but 
  little 
  fluidity 
  

   when 
  cold 
  ; 
  and 
  which, 
  in 
  some 
  cases, 
  partially 
  crystallized. 
  When 
  

   gently 
  heated, 
  it 
  became 
  clear, 
  and 
  of 
  an 
  amber 
  colour. 
  The 
  vapour 
  

   had 
  an 
  agreeable, 
  pungent, 
  aromatic 
  smell. 
  This 
  oil 
  must 
  have 
  been 
  

   pure 
  etherine. 
  

  

  It 
  is 
  not 
  improbable 
  that 
  this 
  oil, 
  which 
  may 
  be 
  considered 
  as 
  devoid 
  

   of 
  sulphuric 
  acid, 
  is 
  more 
  or 
  less 
  liberated 
  in 
  evolving 
  oil 
  of 
  wine, 
  

   according 
  to 
  the 
  nature 
  of 
  the 
  process 
  employed 
  ; 
  and 
  that 
  the 
  oil 
  al- 
  

   luded 
  to 
  by 
  Thenard, 
  and 
  those 
  procured 
  by 
  me 
  by 
  simple 
  distillation, 
  

   ebullition, 
  or 
  distillation 
  with 
  ammonia 
  or 
  potassium, 
  are 
  mixtures 
  of 
  the 
  

   etherine 
  with 
  its 
  sulphate 
  in 
  various 
  proportions. 
  As 
  it 
  is 
  well 
  known 
  

   that 
  the 
  odour 
  of 
  the 
  essential 
  oils 
  is 
  rendered 
  more 
  active 
  by 
  dilution, 
  

   the 
  livelier 
  smell 
  of 
  the 
  solutions 
  may 
  be 
  consistent 
  with 
  a 
  diminished 
  

   proportion 
  of 
  the 
  odoriferous 
  matter. 
  

  

  Oil 
  of 
  wine 
  cannot 
  be 
  distilled 
  per 
  se 
  without 
  partial 
  decomposition, 
  

   which 
  does 
  not 
  take 
  place 
  below 
  the 
  temperature 
  of 
  300. 
  When 
  

   subjected 
  to 
  the 
  distillatory 
  process, 
  over 
  potassium, 
  at 
  a 
  certain 
  tem- 
  

   perature, 
  a 
  brisk 
  reaction 
  ensued, 
  and 
  the 
  oil 
  and 
  metal 
  agglutinated 
  

   into 
  a 
  gelatinous 
  mass. 
  By 
  raising 
  the 
  temperature 
  the 
  mass 
  liquefied, 
  

   and 
  a 
  colourless 
  oil 
  came 
  over, 
  which 
  retained 
  the 
  odour 
  of 
  oil 
  of 
  wine. 
  

   Meanwhile 
  some 
  of 
  the 
  potassium 
  remained 
  unchanged, 
  and 
  appeared 
  

   within 
  the 
  liquid 
  in 
  the 
  form 
  of 
  pure 
  metallic 
  globules. 
  On 
  pouring 
  

   into 
  the 
  retort 
  a 
  portion 
  of 
  nitric 
  acid 
  in 
  order 
  to 
  remove 
  the 
  caput 
  

   mortuum, 
  ignition 
  took 
  place 
  from 
  the 
  presence 
  of 
  the 
  potassium.
