  THE 
  PRODUCTS 
  OF 
  THE 
  

  

  with 
  the 
  aid 
  of 
  heat. 
  The 
  filtered 
  fluid, 
  on 
  cooling, 
  deposited 
  a 
  few 
  tabular 
  

   crystals 
  mixed 
  with 
  a 
  little 
  sal-ammoniac, 
  which 
  was 
  got 
  rid 
  of 
  by 
  a 
  second 
  filtra- 
  

   tion 
  ; 
  and 
  the 
  filtrate, 
  when 
  treated 
  with 
  animal 
  charcoal 
  and 
  further 
  concen- 
  

   trated, 
  solidified, 
  on 
  cooling, 
  into 
  a 
  mass 
  of 
  large 
  foliated 
  crystals. 
  

  

  These 
  crystals 
  are 
  long, 
  transparent, 
  and 
  colourless 
  plates, 
  entirely 
  without 
  

   odour, 
  and 
  with 
  a 
  pungent 
  and 
  bitter 
  taste. 
  In 
  moist 
  air 
  they 
  deliquesce 
  rapidly. 
  

   Solid 
  potash 
  added 
  to 
  their 
  concentrated 
  solution 
  causes 
  the 
  immediate 
  escape 
  of 
  

   a 
  gaseous 
  base 
  resembling 
  ammonia, 
  but 
  distinguished 
  by 
  its 
  peculiar 
  putrid 
  

   odour. 
  This 
  gas 
  dissolves 
  readily 
  in 
  water, 
  and 
  gives 
  a 
  powerfully 
  alkaline 
  solu- 
  

   tion. 
  It 
  gives 
  with 
  corrosive 
  sublimate 
  a 
  fine 
  white 
  precipitate, 
  soluble 
  in 
  hot 
  

   water 
  or 
  spirit, 
  and 
  deposited 
  on 
  cooling 
  in 
  fine 
  silvery 
  plates 
  ; 
  and 
  its 
  hydro- 
  

   chlorate 
  gives, 
  with 
  bichloride 
  of 
  platinum, 
  a 
  soluble 
  salt, 
  depositing 
  from 
  its 
  hot 
  

   saturated 
  solutions 
  in 
  beautiful 
  golden-yellow 
  scales. 
  I 
  selected 
  this 
  salt 
  as 
  a 
  

   means 
  of 
  determining 
  the 
  constitution 
  of 
  its 
  base.

  with 
  which 
  it 
  and 
  its 
  salts 
  agree 
  in 
  

   all 
  respects. 
  

  

  The 
  oily 
  bases 
  which 
  had 
  been 
  separated 
  from 
  their 
  solution 
  in 
  water 
  by 
  

   means 
  of 
  potass, 
  were 
  dried 
  by 
  the 
  addition 
  of 
  successive 
  portions 
  of 
  that 
  sub- 
  

   stance, 
  as 
  long 
  as 
  it 
  continued 
  to 
  become 
  moist. 
  The 
  dry 
  oil, 
  which 
  was 
  very 
  

   dark 
  coloured, 
  was 
  then 
  introduced 
  into 
  a 
  large 
  retort, 
  furnished 
  with 
  a 
  thermo- 
  

   meter 
  and 
  a 
  tubulated 
  receiver 
  kept 
  cold 
  by 
  ice, 
  and 
  connected 
  first 
  with 
  a 
  U 
  tube 
  

   immersed 
  in 
  a 
  freezing 
  mixture, 
  and 
  then 
  with 
  a 
  large 
  vessel 
  of 
  water, 
  in 
  order 
  

   to 
  collect 
  the 
  gaseous 
  bases 
  which 
  began 
  to 
  escape 
  with 
  effervescence 
  almost 
  as 
  

   soon 
  as 
  heat 
  had 
  been 
  applied. 
  At 
  a 
  temperature 
  under 
  150° 
  Fahr. 
  drops 
  began 
  to 
  

   condense 
  in 
  the 
  neck 
  of 
  the 
  retort, 
  and 
  the 
  fluid 
  entered 
  into 
  rapid 
  ebullition. 
  At 
  

   212° 
  the 
  receiver 
  was 
  changed, 
  and 
  the 
  oil 
  distilling 
  above 
  that 
  temperature 
  was 
  

   collected 
  in 
  receivers, 
  which 
  were 
  changed 
  at 
  every 
  ten 
  degrees. 
  

  

  The 
  quantity 
  of 
  bases 
  which 
  distilled 
  under 
  212° 
  was 
  much 
  less 
  than 
  I 
  had 
  anti-
