Remarks. — The  powders  for  this  class  of  extracts  should  be, 
at  least,  so  fine  as  to  pass  through  a  sieve  60  meshes  to  the  linear 
inch,  and  even  dusted  Jalap  and  Ipecacuanha  may  be  employed 
with  advantage.  To  test  the  extracts,  all  that  was  contained  in 
the  original  tinctures,  including  the  sediment  caused  by  the 
evaporation,  was  retained  in  the  vials  without  filtration  as  di- 
rected in  the  recipe,  so  as  to  observe  the  effects  of  keeping.  In 
the  case  of  Jalap  a  very  slight  deposit  of  resinous  matter  adhered 
to  the  bottom.  In  the  Cimicifuga  and  Podophyllum  a  little 
more  of  a  pulverulent  and  flocculent  consistence  separated,  but 
in  quantity  too  small  to  materially  affect  the  activity  of  the  pre- 
parations, even  if  resinous  in  its  nature.  The  Fluid  Extract  of 
Ipecac  will  be  the  proper  means  of  making  the  Syrup,  and  pro- 
perly diluted  it  affords  a  very  energetic  emetic.  The  alcoholic 
strength  of  these  fluid  extracts  is  about  50  per  cent.

EXTRACTUM  COLCHICI  RADICIS  FLUIDUM. 
Take  of  Colchicum  Root  in  powder,  (No.  50,)  16  ounces,

Mix  the  Colchicum  powder  with  four  fluid  ounces  of  the 
diluted  alcohol,  pack  it  closely  in  a  percolator,  cover  the  surface
