  great 
  abundance. 
  I 
  have 
  not 
  yet 
  determined 
  the 
  whole 
  circumstances 
  under 
  

   which 
  this 
  change 
  takes 
  place, 
  but 
  reserve 
  this 
  for 
  a 
  future 
  communication.* 
  

  

  I 
  have 
  likewise 
  examined 
  the 
  action 
  of 
  iodine 
  on 
  codeine, 
  which 
  yields 
  a 
  mag- 
  

   nificent 
  crystalline 
  compound 
  presenting 
  the 
  phenomena 
  of 
  pleochroism 
  in 
  a 
  re- 
  

   markable 
  manner. 
  Difficulties 
  connected 
  with 
  the 
  analysis 
  have, 
  however, 
  pre- 
  

   vented 
  my 
  hitherto 
  completing 
  its 
  investigation.

  The 
  action 
  of 
  nitric 
  acid 
  on 
  the 
  organic 
  alkalies, 
  in 
  this 
  point 
  of 
  view, 
  is. 
  now 
  under 
  investigation 
  

   in 
  my 
  laboratory. 
  Narcotine 
  has 
  been 
  found 
  to 
  undergo 
  a 
  precisely 
  similar 
  change, 
  yielding 
  a 
  compound, 
  

  

  by 
  ebullition 
  with 
  potash, 
  and 
  a 
  whole 
  series 
  of 
  other 
  substances, 
  the 
  con- 
  

  

  stitution 
  of 
  which 
  will 
  be 
  detailed 
  so 
  soon 
  as 
  the 
  investigations 
  are 
  completed.
