  The 
  same 
  scheme, 
  with 
  the 
  addition 
  of 
  two 
  or 
  four 
  equivalents 
  of 
  oxygen, 
  re- 
  

   presents 
  also 
  the 
  mode 
  in 
  which 
  opianic 
  and 
  hemipinic 
  acids 
  respectively 
  are 
  

   derived 
  from 
  narcotine, 
  much 
  more 
  simply 
  than 
  it 
  has 
  been 
  by 
  Blyth* 
  in 
  his 
  

   paper 
  on 
  the 
  action 
  of 
  bichloride 
  of 
  platinum 
  on 
  narcotine, 
  who 
  gives 
  a 
  scheme 
  

   involving 
  the 
  evolution 
  of 
  carbonic 
  acid. 
  The 
  appearance 
  of 
  this 
  gas, 
  which 
  was 
  

   actually 
  observed 
  by 
  Blyth 
  during 
  the 
  action, 
  has, 
  however, 
  always 
  appeared 
  to 
  

   me 
  to 
  be 
  the 
  result 
  of 
  a 
  secondary 
  decomposition 
  ; 
  and 
  this 
  view, 
  I 
  think, 
  receives 
  

   confirmation 
  from 
  the 
  production 
  of 
  teropiammon, 
  where 
  nitric 
  acid 
  acts 
  even 
  in 
  

   the 
  most 
  feeble 
  manner 
  on 
  narcotine, 
  and 
  the 
  formation 
  of 
  which 
  must, 
  of 
  neces- 
  

   sity, 
  be 
  attended 
  by 
  the 
  evolution 
  of 
  carbonic 
  acid. 
  

  

  If 
  we 
  pursue 
  the 
  relations 
  of 
  opianyl 
  to 
  narcotine, 
  we 
  shall 
  find 
  that 
  these 
  

   also 
  are 
  of 
  a 
  very 
  interesting 
  nature. 
  By 
  subtracting 
  an 
  equivalent 
  of 
  cotarnine 
  

   from 
  one 
  of 
  narcotine,

  we 
  find 
  that 
  the 
  substance 
  coupled 
  with 
  cotarnine 
  to 
  form 
  narcotine 
  may 
  be 
  con- 
  

   sidered 
  as 
  a 
  hydruret 
  of 
  opianyl, 
  or 
  a 
  substance 
  bearing 
  to 
  opianyl 
  a 
  relation 
  simi- 
  

   lar 
  to 
  that 
  which 
  alloxantin 
  bears 
  to 
  alloxan, 
  and 
  the 
  preparation 
  of 
  which 
  in 
  a 
  

   separate 
  form 
  would 
  be 
  most 
  interesting. 
  The 
  attempts 
  which 
  I 
  have 
  made 
  to 
  

   obtain 
  it 
  have, 
  however, 
  as 
  yet 
  proved 
  abortive. 
  I 
  have 
  tried 
  the 
  action 
  of 
  sul- 
  

   phuretted 
  hydrogen 
  upon 
  opianyl, 
  but 
  no 
  change 
  took 
  place, 
  and 
  also 
  the 
  fer- 
  

   mentation 
  of 
  narcotine, 
  but 
  with 
  equally 
  little 
  success. 
  Although 
  this 
  hydruret 
  

   of 
  opianyl 
  has 
  not 
  been 
  obtained 
  in 
  a 
  separate 
  form, 
  we 
  have 
  a 
  corresponding 
  

   compound 
  in 
  the 
  sulphopianic 
  acid 
  of 
  Wohler, 
  which 
  may 
  be 
  considered 
  as 
  hydru- 
  

   ret 
  of 
  opianyl, 
  in 
  which 
  the 
  two 
  equivalents 
  of 
  hydrogen 
  are 
  replaced 
  by 
  sulphur.

  and 
  in 
  this 
  point 
  of 
  view 
  the 
  latter 
  substance 
  deserves 
  a 
  further 
  investigation. 
  It 
  

   bears 
  certain 
  analogies 
  in 
  properties 
  to 
  opianyl, 
  and 
  especially 
  gives 
  a 
  purple 
  

   colour 
  when 
  heated 
  with 
  sulphuric 
  acid 
  ; 
  but 
  it 
  appears 
  to 
  possess 
  acid 
  proper- 
  

   ties, 
  although 
  they 
  are 
  certainly 
  very 
  feeble.

  — 
  On 
  one 
  occasion, 
  in 
  acting 
  upon 
  narcotine 
  with 
  nitric 
  

   acid, 
  there 
  was 
  obtained 
  a 
  substance 
  which 
  closely 
  resembled 
  opianyl, 
  but 
  differed
