WINE  OF  CITRATE  OF  IRON  AND  QUINIA. 
By  Samuel  Campbell. 
This  preparation  is  ordinarily  prepared  bj  dissolving  the  salt 
in  "pure  Sherry  wine,"  with  the  aid  of  heat,  the  strength  vary- 
ing from  2  to  5  grains  in  each  teaspoonful. 
From  the  fact  of  my  having  met  with  a  dissimilarity  in  the 
commercial  salt,  in  appearance,  taste  and  solubility,  I  would 
propose  the  following  formula,  as  being  an  eligible  and  a  reliable 
one  for  extemporaneous  prescription,  hoping  that  it  will  prove 
acceptable  to  the  profession  in  general.

Rub  the  quinia  salt  until  perfectly  miscible  with  four  ounces 
of  distilled  water,  then  add  the  diluted  acid  to  form  a  clear 
solution,  pour  it  into  a  decanting  vessel,  and  add  gradually  the 
solution  of  ammonia  until  it  ceases  to  form  a  precipitate,  being 
careful  not  to  have  the  alkaline  solution  in  too  great  an  excess. 
The  precipitate  is  to  be  carefully  washed  with  distilled  water 
until  the  washings  cease  to  evince  any  further  evidence  of  an 
alkaline  reaction  upon  a  piece  of  litmus  paper  previously  red- 
dened with  an  acid.    The  hydrated  quinia  is  then  incorporated 
with  the  citric  acid  and  citrate  of  iron  previously  dissolved  in 
three  ounces  of  boiling  distilled  water.    When  completely  dis- 
solved, add  sufficient  distilled  water  to  make  the  whole  measure 
thirteen  fluid  ounces.   Each  fluid  drachm  of  this  solution  contains 
eight  grains  of  the  double  salt.    In  order  to  prepare  the  wine 
of  the  citrate  of  iron  and  quinia,  it  may  be  readily  done  by 
mixing  two  fluid  drachms  of  the  above  solution  with  six  fluid 
drachms  of  pure  Sherry  wine ;  so  that  each  teaspoonful  will 
contain  two  grains  of  the  salt,  or  the  strength  can  be  varied  to 
meet  the  wants  of  the  physician.
