lodol—  Value  in  Laryngeal  Ulceration, — Dr.  Hajek  uses  iodol  in  laryn-
geal ulceration  of  tubercular  origin,  applying  it  directly  to  the  parts.  Its
slight  solubility  allows  the  powder  to  adhere  to  the  ulcerated  surfaces,  and
it  acts  as  a  marked  detergent ;  under  its  influence  the  ulcer  assumes  the
appearance  of  a  granular  wound.  As  it  adheres  for  three  or  four  days  to
the  surface,  two  insufflations  a  week  will  generally  suffice. — Pharm.  Journ.,

Raphanol — A  Volatile  Crystalline  Body  from  Raphanus  Niger, — H.
Moreigne  has  obtained  a  new  volatile  crystalline  body,  which  he  calls
raphanol,  by  subjecting  the  roots  of  Raphanus  niger  to  slow  distillation
with  water.     It  passes  over  with  volatile  oil,  from  which  it  is  separated  by

recrystallization  from  ether.  Pure  raphanol  forms  white,  pearly,  odorless,
microscopic  crystals,  m.  p.  62^^,  insoluble  in  water,  in  alkali  and  in  weak
acids,  but  readily  soluble  in  ether  and  chloroform,  and  also  in  the  volatile
oil  with  which  it  is  associated.  In  its  ultimate  composition  it  is  found  to
have  the  molecular  formula  C29H56O4,  and  in  its  general  behavior,  deter-
mined as  far  as  the  small  amount  of  material  would  permit,  it  corresponds
to  lactone — a  body  which  has  been  found  by  the  author  in  other  crucifers,
such  as  the  radish,  turnip,  water-cress,  and  scurvy  grass. — Pharm.  Jour.,
