PHARMACY  OF  THE  CINCHONAS. 
in  alkaloids.  Occasionally  a  package  of  Cinchona  is  met  with 
which  yields  a  permanently  transparent  preparation.  But  in 
general  a  small  deposit  occurs  as  soon  as  the  liquid  becomes 
cold,  and  this  increases  in  quantity  slowly  as  long  as  the  prepa- 
ration is  kept,  requiring  that  it  should  be  shaken  up  when  dis- 
pensed or  used.  This  preparation  is  not  too  thick  for  convenient 
use,  and  is  very  bitter  and  aromatic,  but  generally  acceptable  to 
the  stomach. 
The  objections  to  this  preparation  are  exactly  the  same  in 
kind  as  to  the  officinal  Fluid  Extract,  though  by  no  means  the 
same  in  degree.  It  is  however  susceptible  of  the  same  improve- 
ment with  the  same  prominent  advantages  to  be  gained,  and 
therefore  the  following  formula  is  offered  as  a  substitute : 
Extractwn  Cinchonce  Flavce  Fluidum — Fluid  Extract  of 
Calisaya,  with  Aromatics. 
Take  of  Yellow  Cinchona,  in  fine  powder,  sixteen  troyounces. 
Glycerin,  eight  fluidounces,  or  nine  troyounces  and  two 
hundred  and  eighty  grains. 
Aromatic  Fluid  Extract,  (see  further  on,)  a  sufficient 
quantity. 
Alcohol,  six  pints  and  ten  fluidounces. 
Water,  a  sufficient  quantity. 
The  process  and  management  are  precisely  the  same  as  in  the 
Extractum  Cinchonse  Fluidum  Compositum,  see  page  517,  and 
the  preparation  is  the  same  except  in  the  kind  of  aromatics  used, 
and  the  Cinchona  restricted  to  the  Calisaya  or  Yellow  variety. 
The  name  here  proposed  is  objectionable  because  it  is  inconveni- 
ently long,  and  yet  does  not  express  the  compound  character  of 
the  preparation.  The  title  Extractum  Calisaya  Fluidum  would 
be  better,  but  it  is  not  consistent  with  the  Pharmacopoeia  nomen- 
clature, and,  therefore,  should  it  be  accepted  for  the  Pharma- 
copoeia the  name  would  have  to  be  changed. 
The  dose,  mode  of  administration,  etc.,  are  the  same  as  in  the 
simple  fluid  extract. 
The  aromatics  used  here  are  those  which  in  long  service  have 
proved  so  acceptable  in  the  officinal  Pulvis  Aromaticus,  and  it  is 
highly  probable  that  a  better  combination  of  better  aromatics
