tincture  of  cinchona.  Liq.  ferri  citratis  f  3 j  may  be  used  as  a  substitute 
for  the  rather  insoluble  salt.  The  dose  is  a  teaspoonful,  containing  two 
grains  of  citrate  of  iron. 
The  citric  acid  breaks  up  any  tan n ate  of  iron  as  soon  as  formed,  and  it  is 
reproduced  on  the  addition  of  an  alkali.  There  is  a  liability  to  considerable 
precipitate  of  cinchonic  red,  but  very  little  iron  is  thrown  down.
