Calendula  Oil. — What  is  called  calendula  oil,  or  more  correctly 
calendulated  oil,  is  a  soothing  application  to  catarrhal  surfaces,  and 
is  obtaining  favorable  notice  and  use  among  specialists  in  treatment 
of  throat  and  nose  as  a  final  spray  or  dressing  after  the  treatment 
with  an  aqueous  liquid  such  as  Seiler's  solution.

pyroxylon  and  dissolve,  and  finally  the  castor  oil  and  sufficient
