A  New  Incompatibility  with  Resorcin  and  Liquid  Petrolatum. 
L.  L.  Walton. 
The  following  prescription  was  presented  as  having  occasioned 
difficulty  in  compounding  which  was  found  to  be  insurmountable : 
Menthol  3  grains. 
Bucalyptol  3  minims. 
Resorcinol  2  grains. 
Petrolatum,  liquid  y2  fluidounce. 
Ft.  Sol. 
Used  as  a  nasal  spray. 
The  insolubility  of  resorcinol  in  liquid  petrolatum  was  at  once 
recognized,  but  its  property  of  liquefying  when  rubbed  with  menthol, 
it  was  thought  might  possibly  overcome  the  difficulty.  A  turbid 
looking  mixture  resulted,  which  afterwards  separated  a  yellow 
colored  resinous  precipitate  which  gave  the  characteristic  color 
reaction  for  resorcinol  when  separated  and  tested.  Additional  ex- 
periments were  tried,  using  ether,  acetone,  absolute  alcohol  and 
acetic  ether,  without  obtaining  any  satisfactory  results,  so  that  the 
author  was  unable  to  dispense  the  prescription  at  all  as  a  permanent 
solution.  He  therefore  presented  the  paper  in  the  hope  that  some- 
body would  make  a  suggestion  which  would  assist  him  in  overcoming 
the  difficulty.
