ExTEACTUM  AuRANTii  Amari  Fluidum. — Fluid  Extract  of  Bitter 
Orange  Peel. — This  is  also  a  newly-introduced  fluid  extract ;  it  wa& 
recommended  by  tlie  Philadelphia  College  of  Pharmacy,  with  alcohol 
of  the  specific  gravity  '822  as  the  menstruum ;  the  Committee  of" 
Revision  have  directed  a  menstruum  composed  of  two  parts  of  alcohol 
and  one  part  of  water,  instead;  without  having  had  an  opportunity  of 
testing  it,  I  am  inclined  to  think  favorably  of  the  weaker  menstruum. 
This  fluid  extract  is  to  be  made  from  the  orange-peel  in  ribbons  or 
quarters,  with  the  epidermis  of  a  dark  brownish-green  color,  such  as  is 
known  in  commerce  as  Curacoa  orange-peel ;  it  yields  a  preparation 
very  much  su})erior  to  that  made  from  the  ordinary  bitter  orange-peel. 
The  Philadelphia  College  of  Pharmacy  also  recommended  a  fluid 
extract  of  sweet  orange-peel,  made  from  the  recently  dried  yellow 
portion  of  the  peel  of  sweet  oranges,  using  alcohol  as  the  menstruum 
the  Committee  of  Revision,  perhaps  unwisely,  rejected  this  and  directed 
a  tincture  containing  twenty  parts  of  the  peel  in  one  hundred,  also 
using  alcohol  as  the  menstruum. 
ExTRACTUM  Belladonn.e  Fluidum. — FIuhI  Extract  of  Bella- 
doyma. — This  was  oflicinal  in  the  Pharmacopceia  of  1870,  under  the 
name  of  fluid  extract  of  belladonna  root,  and  was  so  recommended  hj 
the  Philadelphia  College  for  the  present  Pharmacopoeia;  as  the  bella- 
donna leaves  are  still  oflicinal,  and  the  tincture  and  alcoholic  extract 
are  directed  to  be  made  from  them,  it  would  certainly  have  been  more 
definite  to  have  retained  the  former  title.  The  menstruum  directed  in 
the  Pharmacopceia  of  1870,  was  alcohol  s.  g.  '835  twelve  fluidounces, 
glycerin  three  fluidounces,  water  one  fluidounce,  finishing  the  percola- 
tion with  diluted  alcohol  s.  g.  '941.  The  menstruum  directed  in  the 
present  Piiarmacopoeia  is  alcohol,  that  recommended  by  the  Philadelphia 
C^ollege  of  Pharmacy  was  alcohol  three  parts,  water  one  part.  Without 
doubting  the  superiority  of  the  product  of  the  oflicinal  process,  it  may 
be  stated  that  the  opinion  of  several  previous  investigators  has  been  in 
favor  of  a  weaker  menstruum. 
ExTRACTUM  Brayer.e  Fluidum. — Fluid  Extract  of  Brayera. — 
The  desirability  of  a  permanent  liquid  preparation  of  koosso  has  long 
been  manifest.  For  this  newly  introduced  fluid  extract,  alcohol  i& 
directed  as  the  menstruum;  various  weaker  alcohols  were  tried  alone 
and  with  glycerin,  but  they  all  precipitated  badly,  even  the  sides  of 
the  bottles  being  covered  with  waxy  resinous  matter.  The  menstruum 
adopted  furnishes  a  good  preparation  with  comparatively  a  slight
