Extraction  Galisayce  Fluidum — Compound  Fluid  Extract  of 
Calisaya  containing  Aromatics. 
The  design  is  to  have  a  fluid  extract  of  which  each  minim  shall 
represent  half  a  grain  of  the  Cinchona,  and  in  which  the  aroma- 
tics  should  have  the  fixed  proportion  of  10  per  cent,  of  the 
weight  of  the  Cinchona,  and  the  sugar  60  per  cent.  Upon  this 
basis  the  formula  was  constructed. 
Take  of  Yellow  Cinchona,  in  fine  powder,  sixteen  troyounces. 
Calamus,  in  fine  powder, 
Cardamon,  in  fine  powder, 
Ginger,  in  fine  powder,  of  each  two  hundred  and 
fifty-six  grains. 
Sugar,  nine  troyounces  and  two  hundred  and  eighty- 
eight  grains. 
Alcohol, 
Diluted  Alcohol, 
Water,  of  each  a  sufficient  quantity. 
Moisten  the  Cinchona  with  twelve  fluidounces  of  Diluted 
Alcohol :  pack  it  firmly  in  a  glass  funnel  prepared  for  percola- 
tion, and  pour  upon  it,  as  required,  three  and  a  half  pints  of 
Diluted  Alcohol,  following  this  with  water  after  the  last  of  the 
Diluted  Alcohol  has  disappeared  from  the  surface,  until  the  per- 
colate becomes  cloudy  and  makes  a  precipitate  in  the  receiving 
flask.  The  percolate  should  measure  about  four  pints.  Reserve 
the  first  pint  received,  and,  having  recovered  the  Alcohol  from 
the  remainder  by  distillation,  boil  the  residue  down  to  six  fluid- 
ounces.  To  this  add  the  sugar,  and,  having  stirred  the  mixture 
until  the  sugar  is  entirely  dissolved,  add  the  reserved  percolate, 
stir  well,  and  strain  while  hot. 
Mix  the  aromatics,  moisten  the  powder  with  half  a  fhiidounce 
of  Alcohol,  pack  it  in  a  small  funnel  prepared  for  percolation, 
and  percolate  it  with  Alcohol  until  the  percolate  obtained  when 
added  to  the  fluid  extract  be  sufficient  to  make  the  measure  up 
to  two  pints. 
This  finished  fluid  extract  is  of  a  very  dark  reddish  brown, 
nearly  black,  color  and  more  or  less  turbid  from  some  undiscover- 
ed differences  in  different  lots  of  Cinchona  of  the  same  richness
