Moisten  the  cinchona  with  the  dilute  alcohol,  and  pack  in  a  glass 
funnel,  in  the  neck  of  which  sufficient  tow  (free  from  tar)  has  been 
placed  to  act  as  a  filter ;  cover  the  surface  with  a  piece  of  perforated 
paper,  and  pour  on  alcohol  previously  mixed  with  an  equal  volume  of 
syrup  until  it  has  reached  the  tow  and  the  surface  of  the  powder  is 
covered  ;^,cork  the  neck  of  the  funnel  and  allow  it  to  macerate  forty- 
eight  hours  ;  then  remove  the  cork  and  continue  the  percolation  with

Moisten  the  cinchona  with  f^iss  of  dilute  alcohol,  and  pack  in  per- 
colator (with  tow  in  the  neck  to  act  as  filter),  and  pour  on  dilute

sugar  in  the'/tincture  by  agitation. 
This  contains  fifteen  grains  red  Peruvian  bark  in  each  fluiddrachm. 
I  prefer  the  first  process  for  exhausting  the  bark,  for  the  reason  that 
the  alcohol  is  stronger,  being  diluted  with  syrup  instead  of  water.
