522  PHARMACY  OF  THE  CINCHONAS. 
bat  feeble  tonics/their  properties  as  stomachic  aromatics  simply, 
would  hardly  warrant  their  selection  as  best  adapted  to  these 
preparations  of  Cinchona,  and  the  writer  has  long  thought  it 
would  be  judicious  to  abandon  them  in  favor  of  more  effective 
stimulant  aromatics,  and  in  the  early  part  of  the  late  war,  when 
called  upon  to  devise  a  good  vegetable  tonic  for  general  army 
use,  did  not  hesitate  to  abandon  these,  notwithstanding  the 
many  years  of  accumulated  experience  with  the  well-known 
Huxham's  Tincture.  The  Serpentaria  being  regarded  as  scarce- 
ly more  than  an  aromatic  in  the  small  quantity  used,  Calamus, 
Cardamon  and  Ginger  were  substituted  for  the  three  with  sup- 
posed advantage,  and  Calisaya  or  Yellow  Cinchona  was  substi- 
tuted for  Red  Cinchona,  as  being  a  more  uniform  Bark,  the  good 
varieties  of  which  were  more  easily  accessible,  and  as  containing 
a  larger  proportion  of  the  most  important  alkaloid,  and  there- 
fore better  adapted  as  a  tonic  to  the  miasmatic  localities  in  which 
it  would  be  often  used.  The  name  adopted  for  it  at  the  time  it 
was  devised  and  first  used  in  the  Army  was  Extractum  Cinchonse 
Fluidum.  But  when  the  Committee  of  Final  Revision  of  the 
Pharmacopoeia  declined  to  adopt  it,  and  adopted  the  present 
officinal  fluid  extract  by  this  name,  which  was  far  more  appro- 
priate to  the  simple  officinal  preparation  than  to  this  compound 
preparation,  it  became  necessary  to  change  the  name  in  order  to 
avoid  confusing  interference  with  the  Pharmacopoeia.  It  was 
then  changed  to  Extractum  Calisayse  Fluidum,  by  which  title  it 
is  now  somewhat  largely  and  perhaps  favorably  known.  During 
the  war  more  than  10,000  pounds  of  it  were  dispensed  from  the 
Army  Purveying  Depots.  The  recent  Revising  Board  still  re- 
tained it  upon  the  Army  Supply  Table,  and  its  reputation  in 
civil  practice  seems  still  pretty  well  sustained  in  use,  and  there 
can  be  little  doubt  that  when  made  from  good  materials  it  is 
an  efficient  and  valuable  preparation.  Since  the  first  publica- 
tion of  the  formula  it  lias  been  twice  slightly  modified, — once 
when  presented  to  the  Committee  of  Revision,  and  once  since. 
Both  changes  are  believed  to  have  been  adopted  by  the  Army 
Laboratories,  and  the  formula  now  to  be  given  has  been  in  use 
since  September,  1865.
