ExTRAcn^UM  Krameri^  Fluidum. — Fluid  Extract  of  Krameria. — 
For  this  preparation  the  Pharmacopoeia  of  1870  directed  a  menstruum 
composed  of  eight  fluidounces  of  alcohol,  three  fluidounces  of  glycerin^ 
and  five  fluidounces  of  water,  finishing  the  percolation  with  diluted 
alcohol,  and  adding  one  fluidounce  of  glycerin  to  the  dilute  percolate 
before  evaporation.  The  present  Pharmacopoeia  directs  diluted  alcohol^ 
with  twenty  per  cent,  of  glycerin  in  the  first  one  hundred  parts  of  the 
menstruum,  and  the  Philadelphia  College  of  Pharmacy  recommended 
the  same.  A  sample  thus  made  in  December,  1879,  has  kept  tolerably 
well,  has  almost  no  precipitate,  is  quite  thick  but  not  gelatinized,  is  of 
a  deep  red  color,  and  not  quite  transparent  in  thin  layers ;  another 
sample  made  at  the  same  time,  but  with  only  ten  per  cent,  of  glycerin, 
is  also  without  precipitate,  is  comparatively  thin,  of  a  deep  red  color, 
and  perfectly  transparent  in  thin  layers.  It  would  therefore  seem  that 
the  officinal  formula  would  be  improved  by  the  use  of  ten  per  cent,  of 
glycerin  instead  of  twenty. 
ExTRACTUM  Lactucarii  Fluidum. — Fluid  Extract  of  Lactu- 
carium. — This  is  one  of  the  eleven  fluid  extracts  added  to  the  list  by 
the  Committee  of  Revision.  The  Pharmacopoeia  directs  a  most  elab- 
orate and  complicated  procedure,  which,  if  carefully  worked  out,  yields 
a  fluid  extract  that  will,  when  mixed  with  syrup,  furnish  that  much- 
desired  preparation,  a  permanently  clear  syrup  of  lactucarium  ;  although 
there  is  considerable  demand  for  this  syrup,  it  seems  a  pity  that  so 
much  pharmaceutical  skill  and  labor  should  be  required  for  the  prep- 
aration of  a  drug,  of  which  a  recognized  medical  authority  speaks  of  as 
being  possibly  desirable  for  persons  with  whom  faith  in  a  remedy  sup- 
plies its  want  of  intrinsic  efficiency. 
ExTRACTUM  Left ANDR^  Fluidum. — Fluid  Extract  of  Leptandra. 
— This  is  one  of  the  newly -introduced  fluid  extracts;  the  Pharma- 
copoeia directs  a  menstruum  composed  of  diluted  alcohol,  with  fifteen 
per  cent,  of  glycerin  in  the  first  one  hundred  parts,  and  the  Phila- 
delphia College  of  Pharmacy,  two  parts  of  alcohol,  and  one  part  of 
water;  a  sample  thus  made  in  November,  1879,  contains  now  only  a 
moderate  precipitate,  about  the  one-eighth  of  an  inch  deep  in  a  four-
