Dissolve  the  Iodoform  in  the  Acetone,  add  the  Eucalyptol,  Oleic 
Acid  and  the  Liquid  Petroxolin  and  mix  the  ingredients. 
Despite  the  statements  in  the  books  3  per  cent,  of  iodoform 
cannot  be  dissolved  in  Liquid  Petrox  alone ;  even  if  heat  be  used, 
only  a  portion  will  dissolve  and  this  largely  crystallizes  out  on 
cooling.  Consequently,  one  of  the  solvents  for  iodoform  must  be 
made  use  of  and  for  this  purpose  we  selected  acetone.  The  dis- 
agreeable odor  of  iodoform  is  modified  and  largely  overcome  by 
the  combination  of  eucalyptol  and  lavender. 
Dissolve  the  Menthol  in  the  Liquid  Petroxolin  by  agitation. 
The  Br.  Ph.  Codex  makes  this  only  2  per  cent. ;   we  have 
followed  the  trade  lists  in  making  it  5  per  cent.
