The  precipitate  of  cinchona  red,  and  resinous  matter,  which 
is  discarded  in  most  formulas,  or  only  partially  incorporated,  is 
of  particular  importance  ;  and  the  presence  of  the  small  amount 
of  alcohol  renders  less  sugar  necessary,  for  preservation,  than

Each  fluid-ounce  will  represent  one  half  an  ounce  of  the  crude 
material  (which  is  the  proportion  recognized  in  most  of  the  for- 
mulas I  have  seen ;)  medium  dose,  one  drachm. 
The  fluid  extract  is  advantageously  used,  also,  in  the  prepara- 
tion of  the  infusions,  and  decoctions, — and  in  addition  to  other 
mixtures. 
The  following  articles  I  have  manufactured  for  some  time,  and 
fchey  have  met  with  a  favorable  reception  from  many  : — 
Tincture  of  Calisaya — Aromatic. 
jj.    Calisaya  Bark,  coarsely  powdered,    one  lb.  avoird. 
Ceylon  Cinnamon,       .  " 
Cardamom  Seeds,        .  " 
Jamaica  Ginger,         .        "         of  each  1 J  drs. 
Purest  deodorized  Spirits,  five  pints. 
Macerate  and  displace,  and  add— 
Sherry  Wine,  ....        two  pints. 
Tincture  Angelica,  .       .       .        one  fluid-drachm. 
Simple  Syrup,        .       .       .        one  pint. 
Allow  it  to  stand  a  few  days,  decant  and  filter. 
Dose — one  half  to  one  table-spoonful. 
This  is  an  efficient  preparation,  and  pleasantly  taken. 
Wine  of  Peruvian  Bark. 
r.    True  Red,  or  Calisaya  Bark,  well  bruised,    six  oz. 
Sherry  Wine,  four  pints.

filter. 
Dose — one-half  to  one  wine-glassful. 
It  may  be  sweetened  to  suit  the  taste,  when  taken.  This  was 
intended  as  a  substitute  for  the  wine  and  bark  so  frequently  used, 
and  possesses  the  advantages  of  elegant  appearance,  with  equal 
and  determinate  strength. — Medical  Independent,  Sept.,  1857.
