  Opianyl 
  thus 
  bears 
  a 
  very 
  interesting 
  relation 
  to 
  opianic 
  and 
  hemipinic 
  acids, 
  

   provided 
  we 
  assume 
  for 
  the 
  former 
  the 
  formula 
  as 
  corrected 
  by 
  Berzelius. 
  and, 
  

   for 
  the 
  latter, 
  an 
  atomic 
  weight 
  twice 
  as 
  high 
  as 
  that 
  assigned 
  to 
  it 
  by 
  Wohler, 
  

   both 
  of 
  which 
  assumptions 
  are 
  consistent 
  with 
  analyses 
  which 
  will 
  be 
  detailed 
  in 
  

   the 
  sequel. 
  The 
  three 
  substances 
  then 
  stand 
  as 
  follows 
  :

  Opianyl,

  and 
  appear 
  as 
  three 
  successive 
  degrees 
  of 
  oxidation 
  of 
  the 
  same 
  radical. 
  I 
  have 
  

   not 
  attempted 
  to 
  convert 
  opianyl 
  into 
  opianic 
  acid 
  by 
  oxidation, 
  as 
  the 
  quantity 
  

   at 
  my 
  disposal 
  was 
  not 
  sufficiently 
  large 
  to 
  admit 
  of 
  an 
  accurate 
  experiment, 
  but 
  

   no 
  reasonable 
  doubt 
  can 
  be 
  entertained 
  on 
  that 
  subject. 
  

  

  The 
  derivation 
  of 
  opianyl 
  from 
  narcotine 
  is 
  abundantly 
  simple. 
  Two 
  equiva- 
  

   lents 
  of 
  hydrogen 
  are 
  oxidised 
  by 
  the 
  nitric 
  acid, 
  and 
  the 
  narcotine 
  splits 
  up 
  into 
  

   opianyl 
  and 
  cotarnine, 
  as 
  is 
  expressed 
  in 
  the 
  following 
  scheme 
  :
