Bromide  of  Iron. — The  solution  of  this  salt  does  not  keep  well, 
and  is  at  once  made  up  into  syrup  or  pills.  It  is  made  by  using  40 
grams  of  iron  filings,  216  grams  distilled  water  and  80  grams  bromine, 
and  contains  one-third  its  weight  of  ferrous  bromide. 
Pills  of  Ferrous  Bromide.  —  15  grams  of  the  preceding  solution 
and  10  grams  powdered  iron  are  evaporated  in  a  porcelain  capsule,  until 
the  water  has  been  driven  off" ;  the  mass,  while  still  hot,  is  transferred 
to  a  warm  mortar,  mixed  with  sufficient  powdered  gum  arabic  and 
licorice  root  until  a  mass  is  obtained,  which  is  divided  into  100  pills  ; 
they  are  to  be  rolled  in  lycopodium  or  covered  with  a  mixture  of  gum 
and  sugar. 
Syrup  of  Ferrous  Bromide. — 15  grams  of  the  solution  are  mixed  with 
985  grams  of  syrup  of  gum,  flavored  with  orange-flower  water. 
Ferrous  chloride  is  made  by  dissolving  iron  in  hydrochloric  acid 
and  evaporating  the  filtered  solution  rapidly  to  dryness. 
Syrup  of  Ferrous  Chloride. — -Dissolve  5  grams  of  dry  ferrous  chlor- 
ide in  20  grams  of  orange-flower  water,  and  add  800  grams  syrup 
of  gum  and  175  grams  syrup  of  orange-flower. 
Pills  of  Ferrous  Chloride. — Dry  ferrous  chloride,  powdered  marshmal- 
low-root,  each  10  grams,  mucilage  sufficient.  Make  into  100  pills, 
which  are  to  be  silvered. 
Dialyzed  Oxide  of  Iron. — 100  grams  solution  of  ferric  chloride  of 
30°B.,  are  mixed  in  small  quantities  with  35  grams  ammonia  water  of 
22°B.  The  precipitate  dissolves  at  first  rapidly,  afterwards  very  slowly. 
When  the  liquid  has  become  transparent  it  is  introduced  into  a  dialysa- 
tor,  and  this  placed  in  distilled  water,  which  is  to  be  frequently  renewed, 
until  the  liquid  is  no  longer  precipitated  by  nitrate  of  silver  and  is  des- 
titute of  acid  reaction.  It  still  contains  a  small  quantity  of  hydro- 
chloric acid,  which  may  be  recognized  by  precipitating  with  ammonia, 
acidulating  with  nitric  acid  and  testing  with  silver  nitrate.  10  cc.  of 
the  liquid,  which  is  entirely  free  from  disagreeable  ferruginous  taste, 
are  evaporated,  and  from  the  weighed  residue  the  amount  of  water  is 
calculated  which  must  be  added  to  obtain  a  solution  containing  in  100  cc. 
1  gram  of  solid  matter. 
Syrup  of  Ferrous  Chlorhydro-phosphate. — Ferrous  chloride, 
medicinal  phosphoric  acid,  of  each  5  grams  ;  distilled  water  350  grams  ; 
sugar  640  grams.     Make  a  syrup.
