Dissolve  the  sulphate  of  iron  in  seven  ounces  of  boiling  water,  and 
the  phosphate  of  soda  in  twelve  ounces  of  boiling  water ;  mix  them 
in  a  precipitating  jar  and  carefully  wash  the  precipitated  phosphate 
of  iron;  add  the  phosphoric  acid  to  sxx  of  distilled  wafer,  apply 
gentle  heat  on  a  sand-bath  until  dissolved,  then  introduce  the  nitric 
acid,  and  continue  the  application  of  heat  until  the  solution  is  reduced 
to  the  measure  of  seventeen  ounces,  or  until  the  fumes  of  nitric  acid 
cease  to  be  evolved  ;  dissolve  the  quiniae  by  aid  of  the  dilute  sulphuric 
acid  in  four  ounces  of  water,  and  precipitate  the  alkaloid  by  aqua 
ammoniae  slowly  added,  and  carefully  wash  ;  dissolve  the  phosphate  of
