SYRUP  OF  BROMIDE  OF  IRON. 
By  M.  H.  Stiles,  M.P.S. 
"^I  noticed  in  a  recent  number  of  the  Journal  a  formula  for  syrup  of 
bromide  of  iron,  taken  from  a  French  paper  on  the  subject.  About 
six  weeks  ago,  I  had  occasion  to  prepare  some  of  the  syrup  for  a  pre- 
scription. This  was  made  to  contain  three  grains  of  bromide  of  iron 
in  each  fl.^i.,  which,  from  inquiries  I  have  since  made,  is  the  strength 
usually  recommended  in  this  country. 
1 1  The  syrup  made  by  M.  Prince  is  only  about  one-seventh  this  strength, 
and  is  scarcely  in  accordance  with  English  ideas  of  what  such  a  pre- 
paration should  be.    The  following  is  the  process  I  adopted  : 
Take  of — 
Thin  Iron  Wire,  free  from  rust,      .       .  .        J  oz. 
Bromine,      .......       320  grs. 
Distilled  Water,       .       .       .       .       .  .       1  oz. 
Put  the  wire  and  water  in  an  8-oz.  flask,  the  lower  portion  of  which 
is  placed  in  a  vessel  of  cold  water,  add  the  bromine  gradually,  cork- 
ing the  flask  after  each  addition,  and  taking  care  that  one  portion  is 
neutralized  before  another  is  poured  in.  When  all  the  bromine  has 
been  added,  heat  the  flask  gently  until  the  brown  color  disappears, 
and  filter  the  solution,  whilst  hot,  through  paper  ;  wash  the  wire  with 
a  little  distilled  water,  filter  the  washings,  add  them  to  the  filtrate, 
and  make  the  resulting  liquid  measure  fl.3 ii.  Mix  this  with  fl.^xvi. 
of  syrup.    One  fluid-drachm  contains  three  grains  of  FeBr2. 
If  the  flask  be  not  kept  cool,  and  the  process  controlled  in  the  man- 
ner directed,  the  action  becomes  so  violent  that  a  considerable  por- 
tion of  the  bromine  is  lost. 
Bromide  of  iron  is  also  given  in  combination  with  bromide  of  qui- 
nia or  bromide  of  strychnia,  or  with  both,  the  amount  of  these  in  fl.gi 
of  the  syrup  being  one  grain  and  3^  grain  respectively. — Pharm.  Journ,

Some  time  ago,  a  sample  of  coca  leaves,  weighing  several  pounds,
