Extracts,  Fluid.  ^».  Extbaota  vluida,
KxTUAOTA  LIQUIDA,  L.  This  name  has  been
applied  in  modern  pharmacy  to  Tarious  prepa-
rrttious  difl'ering  materially  from  each  other  in
Ihuir  degree  of  fluidity  and  concentration,
tiome  of  these  have  been  already  noticod,  and
others  will  be  found  under  one  or  other  of
their  s.Tnonyms.  Much  confusion  would  be
avoided  by  confining  the  name  '  jluid  ei-
TBAOT '  to  those  preparations  only  which  differ
from  the  -ordinary  ofiicinal  extracts  in  being
in  the  liquid  form  ;  whilst  others  of  a  like  cha-
racter, but  of  less  consistence  or  concentra-
tion, might  bo  conveniently  classed  under  the
general  denomination  of  liquobb'  (liqitobeb,
L.).  The  various  condensed  preparations  of
vegetable  substances,  now  common  in  trade,
professedly  several  times  stronger  than  the
common  DEOOOIIONB,  INHTSIOHS,  and  tino-
TVBSB,  might  be  simply  and  advantageously
distinguished  by  the  addition  of  '  CONOBM-
TBATED  '  to  their  names.  Tinctures  made  with
rectified  spirit,  and  of  (say)  at  least  8  times
the  usual  strength,  might  be  appropriately
termed  '  kssenc  es.'  See  Deoociiok.  Essbmcb,

SACCnAEO,  L.  Prep.  1.  Ordimiry  soft  ox-
tract  of  the  drug,  4  piirts ;  white  sugar  (in
powder),  1  part;  mix,  and  dry  by  exposure  in
a  warm  situation ;  histly,  reduce  the  mass  to
powder,  and  if  it  weighs  loss  than  4  parts,  tri-
turate it  with  more  powdered  sugar  until  its
weight  is  equal  to  the  original  weight  of  the
extiiut  used  in  its  preparatiou.  The  strength
of  the  extract  thus  continues  unchanged.
2.  (Ph.  Bor.)  As  the  last,  but  using  pow-
dered sugar  of  milk,  in  lieu  o(  cane  sugar.
