an  iodated  iodide  of  potassium  prepared  after  the  following  formula  : 
Iodine,  10  gm. ;  iodide  of  potassium,  10  gm. ;  water,  1,000  gm.  The 
reagent  should  not  be  used  in  excess.  The  liquor  should  always  be 
allowed  to  retain  a  little  of  the  sulphate  of  cinchonine.  The  product 
is  placed  on  a  filter,  and  is  washed  with  water  until  the  latter  no 
longer  contains  iodine,  after  which  it  should  be  dried  in  the  open 
air.  The  iodosulphate  of  cinchonine  is  a  well-defined  product, 
which  contains  50  per  cent,  of  iodine.  It  may  be  obtained  crystal- 
lized, but  for  medical  uses  it  is  best  made  in  accordance  with  the 
formula  described. 
Chloroformic  Digitalin. — In  a  long  article  on  the  active  prin- 
ciples of  digitalis,  Dr.  Bardet  {Nouv.  Rem.,  July  24)  presents  his 
conclusions  as  follows:  1.  In  order  to  feel  assured  that  we  may 
obtain  a  product  of  even  activity,  we  should  always  prescribe  chloro- 
formic digitalin.  2.  All  chloroformic  digitalins  should  be  totally 
soluble  in  chloroform.  3.  There  is  an  equality  of  action  between 
crystallized  digitalin  and  amorphous  chloroformic  digitalin.  German 
digitalin,  or  digitalein,  are  products  having  so  great  an  inequality 
of  action,  that  they  should  be  excluded  absolutely  from  thera- 
peutics. 
Aristol  Plasters. — M.  Cavailles  makes  these  for  the  Hopital 
Saint-Louis  by  mixing  finely  powdered  aristol  with  a  small  quantity 
of  oil,  and  adding  to  a  mass  of  lanolin  and  caoutchouc  plaster,  pre- 
viously cooled  and  made  very  fluid  by  the  addition  of  benzin.  The 
benzin  is  evaporated  to  a  sufficient  degree  to  leave  a  preparation 
suitable  for  spreading  upon  muslin.  The  plasters  are  said  to  possess 
the  full  antiseptic  properties  of  aristol  applied  in  other  ways.  The 
author  makes  plasters  of  iodol,  iodoform,  salol  and  chrysarobin  in 
the  same  manner. — L  Union  Phar.,]u\y. 
Burns  from  Hydrofluoric  Acid. — M.  Desvignes  (R'epert.  de 
Phar.,  Sept.  10)  describes  the  case  of  an  engraver  on  glass  whose 
skin  was  burned  while  handling  hydrofluoric  acid.  The  treatment 
recommended  is  to  wash  the  burned  parts  with  a  largely  diluted 
milk  of  lime  or  magnesia.  Ammonia  is  used,  but  is  usually  made 
too  strong,  considering  the  small  quantity  of  hydrofluoric  acid 
present,  and  the  excess  of  ammonia  has  too  caustic  an  action  on  the 
burned  skin. 
Rapid  Preparation  of  Mercurial  Ointment. — M.  Passerieux 
proposes  a  method,  which  consists  of  putting  a  small  quantity  of
