Preparations  of  Bromide  of  Iron. — Mr.  Prince  proposes  a  standard 
solution,  containing  one-third  of  its  weight  of  the  bromide,  and  which 
is  prepared  by  pouring  into  a  quart  llask  100  grams  iron  filings,  free 
from  rust;  768  grams  water,  and  210  grams  bromine,  the  latter  to  be 
added  in  five  portions;  loss  of  bromine  evaporation  is  avoided  by 
keeping  the  orifice  closed  with  a  cork.  After  combination  has  been 
effected,  the  contents  of  the  flask,  including  the  iron,  are  transferred 
to  a  suitable  bottle,  which  is  kept  well  stopped.  Of  the  clear  liquid, 
30  grams  are  rapidly  evaporated  to  dryness,  and  the  residue  should 
weigh  exactly  10  grams. 
Troches  of  Bromide  of  Iron  are  made  by  evaporating  18  grams  of 
the  standard  solution  to  one-half,  and  incorporating  it  with  an  inti- 
mate mixture  of  1*5  grm.  powdered  tragacanth  and  100*5  grm.  sugar  "7 
the  mass  to  be  divided  into  120  troches. 
For  Pills  of  Bromide  of  Iron ,  12  grm.  of  the  standard  solution  and 
0*1  grm.  powdered  iron  are  evaporated  to  expel  all  the  water,  and  the 
residue  while  still  hot  is  rapidly  mixed,  in  a  warm  and  dry  mortar, 
with  sufficient  powdered  liquorice  root  and  gum  arabic ;  the  mass  to 
be  divided  into  80  pills.  Each  lozenge  and  pill  contains  0*05  grm.? 
or  f  gr.  of  ferrous  bromide. 
A  Sprup  of  Bromide  of  Iron  is  proposed  to  be  made  by  mixing  12 
grm.  of  the  standard  solution  with  620  grm.,  or  half  a  litre  of  gum 
syrup  flavored  with  orange-flower  water. — U  Union  Pharmac,  1874,, 
July. 
Syrup  of  Hypophosphite  of  Iron  is  recommended  by  P.  Carles  to  be 
made  by  dissolving  15  grm.  of  ferrous  sulphate  in  20  grams,  and  9*14 
grm.  of  crystallized  hypophosphite  of  calcium  in  330  grm.  of  hot  dis- 
tilled water;  the  mixed  solutions  are  forcibly  agitated,  after  fifteen 
minutes  the  magma  is  thrown  upon  a  linen  strainer,  expressed,  the 
liquid  filtered  through  paper,  and  enough  water  added  to  make  the 
weight  of  the  filtrate  360  grams,  in  which  660  grams  of  sugar  are  to 
be  dissolved  by  the  aid  of  a  moderate  heat. 
The  syrup  should  be  kept  in  bottles,  well  filled.  Each  tablespoonful, 
weighing  25  grams,  contains  0*25  grams  of  the  hypophosphite.  If 
mixed  with  an  equal  quantity  of  orange-flower  syrup,  it  has  a  very 
agreeable  taste. — Ibid.
