  Hydriodate 
  of 
  Codeine 
  is 
  obtained 
  by 
  dissolving 
  codeine 
  in 
  hot 
  hydriodic 
  

   acid, 
  and 
  allowing 
  the 
  solution 
  to 
  cool. 
  It 
  is 
  deposited 
  in 
  long 
  slender 
  needles, 
  

   which 
  fill 
  the 
  whole 
  fluid, 
  if 
  it 
  have 
  been 
  sufficiently 
  concentrated. 
  It 
  is 
  of 
  rather 
  

   sparing 
  solubility 
  in 
  cold 
  water, 
  requiring 
  about 
  60 
  times 
  its 
  weight, 
  but 
  is 
  much 
  

   more 
  soluble 
  in 
  boiling 
  water. 
  Its 
  saturated 
  cold 
  solution 
  is 
  precipitated 
  by 
  am- 
  

   monia 
  on 
  standing. 
  No 
  difficulty 
  was 
  experienced 
  in 
  its 
  analysis.
