  Sulphate 
  of 
  Narceine 
  is 
  deposited 
  from 
  its 
  solution 
  in 
  tufts 
  of 
  silky 
  needles, 
  

   not 
  differing 
  much 
  in 
  appearance 
  from 
  the 
  base 
  itself. 
  It 
  is 
  of 
  rather 
  sparing

  of

  of 
  platinum 
  

   is 
  added 
  to 
  hydrochlorate 
  of 
  narceine, 
  the 
  double 
  compound 
  is 
  deposited 
  sometimes 
  

   in 
  prismatic 
  crystals 
  of 
  small 
  size, 
  and 
  sometimes 
  as 
  a
