Sozoiodol  dusting-powder,  composed  of  sozoiodol,  10,  and  pow- 
dered starch  or  talc,  90  parts,  is  recommended  by  Dr.  Ostermayer 
{Deutsche  Mediz.  Uochensch.)  in  burns  caused  by  direct  flame,  hot 
steam  or  chemicals,  like  caustic  alkalies.  The  powder  is  odorless, 
not  poisonous,  allays  pains  and  prevents  suppuration. 
Catarrh  Snuffs. — The  Jour,  de  Med.  de  Paris  gives  the  following 
in  chronic  coryza :  Alum,  2;  borax,  2;  zinc  tannate,  3;  bismuth 
tannate,  3 ;  lycopodium,  8  ;  menthol,  o-2  gm. 
In  scrofulous  complications,  the  snuff  is  prepared  of  zinc  sulpho- 
phenate,  o-2 ;  zinc  tannate,  2  ;  iodol,  3  ;  bismuth  salicylate,  4,  and 
powdered  tobacco,  10  gm. 
Another  formula  directs  naphthaline  25  ;  boric  acid,  25,  and 
camphor,  1  part. 
Ammonium  carbonate,  given  in  frequently  repeated  and  rather 
large  doses,  is  stated  by  Dr.  B.  Robinson  to  be  one  of  the  best  agents 
for  aborting  a  coryza. 
Suppositories  of  chloral  are  recommended  by  Yvon  to  be  combined 
with  belladonna  to  prevent  irritation,  as  follows  :  Chloral  hydrate, 
0-5  ;  extr.  belladonna,  0-3  ;  cacao  butter,  3-0  gm. — Rev.  de  Clinique. 
Quinine  and  Antipyrine. — Greuel  (Apoth.  Ztng.,  1889,  P-  1 3^5) 
again  draws  attention  to  the  fact  that  quinine  is  rendered  more 
soluble  by  the  addition  of  antipyrine.  He  states  further  that  such 
a  solution  does  not  give  the  thalleioquin  reaction,  but  yields  a  flesh- 
colored  precipitate,  which  crystallizes  from  alcohol  in  needles.  This 
indicates  that  a  chemical  reaction  has  taken  place  between  the  two 
compounds,  but  the  product  has  not  as  yet  been  studied. 
Carbolic  Acid  and  Bromine. — Sehrwald  (Rundschau,  Prag)  found 
in  carbolic  acid  an  agent  for  counteracting  the  effects* of  bromine. 
Inhalations  of  phenol  are  stated  to  allay  the  pain  resulting  from  the 
inhaling  of  bromine  vapors.  A  2  per  cent,  solution  of  phenol  is 
beneficial  in  treating  bromine  burns  on  the  skin. 
Caoutchouc  plasters  are  prepared  by  Dr.  Schneegans  and  M. 
Corneille  (Jour.  d.  Phar.  v.  Elsass-Lothr.,  Feb.,  1890,  p.  33,)  from 
a  mass  consisting  of  lanolin,  benzoinated  tallow,  caoutchouc  and 
dammar  resin,  the  last  two  ingredients  being  employed  merely  in 
sufficient  quantity  to  insure  adhesiveness.  The  addition  of  a  little 
glycerin  prevents  the  plaster  from  becoming  dry  and  brittle.  Sheet 
caoutchouc  is  agitated  with  and  macerated  in  5  times  its  weight  ot 
benzol ;  at  first  it  swells  and  in  about  3  or  4  days  it  dissolves.
