  Couerbe's 
  formula 
  agrees 
  extremely 
  well 
  with 
  his 
  analytical 
  results, 
  but 
  it, 
  

   as 
  well 
  as 
  Pelletier's, 
  is 
  entirely 
  unsupported 
  by 
  determination 
  of 
  the 
  atomic 
  

   weight, 
  which 
  neither 
  of 
  them 
  seem 
  to 
  have 
  attempted, 
  owing 
  to 
  the 
  impression 
  

   they 
  derived 
  from 
  their 
  experiments, 
  that 
  narceine 
  does 
  not 
  possess 
  basic 
  proper- 
  

   ties, 
  an 
  opinion 
  which 
  I 
  have 
  found 
  to 
  be 
  altogether 
  incorrect.

  Analysis 
  of 
  Narceine. 
  

  

  The 
  analysis 
  of 
  narceine 
  was 
  made 
  upon 
  a 
  quantity 
  which 
  had 
  been 
  purified 
  

   by 
  repeated 
  solution 
  both 
  in 
  water 
  and 
  alcohol, 
  and 
  which 
  was 
  absolutely 
  white. 
  

   It 
  loses 
  its 
  water 
  with 
  great 
  difficulty 
  at 
  212°, 
  and 
  it 
  is 
  most 
  convenient 
  to 
  dry 
  it 
  

   at 
  230°.
