sample  made  at  the  same  time  as  the  first,  with  dihited  alcohol,  has- 
likewise  only  a  moderate  precipitate,  but  there  is  on  the  sides  of 
the  bottle,  above  the  fluid  extract,  a  considerable  coating  of  yellowish 
substance;  in  other  respects  this  sample  is  in  moderately  good  condition^ 
but  the  stronger  menstruum  is  evidently  the  best  for  this  preparation. 
ExTRACTUM  Stramonii  Fluidum. — Fluid  Extract  of  Stramonium^ 
This  is  one  of  the  eleven  fluid  extracts  added  to  the  list  by  the  Com- 
mittee of  Revision;  it  is  directed  to  be  made  from  the  powdered  stra- 
monium seed  with  a  menstruum  composed  of  three  parts  of  alcohol 
and  one  part  of  water;  the  product  no  doubt  well  represents  the  drug,, 
but  having  this  preparation,  the  oflicinal  tincture  of  stramonium 
a})pears  to  be  entirely  superfluous,  and  if  the  same  menstruum  had  been 
directed,  the  solid  extract  might  have  been  very  conveniently  obtained 
from  the  fluid. 
ExTRACTUM  Taraxaci  Fluidum. — Fluid  Extract  of  Taraxa- 
cum.— For  this  preparation  the  Pharmacopoeia  of  1870  directed  a 
menstruum  composed  of  eight  fluidounces  of  alcohol,  three  fluidounce& 
of  glycerin,  and  five  fluidounces  of  water,  finishing  the  percolatiou 
with  diluted  alcohol,  and  adding  one  fluidounce  of  glycerin  to  the 
dilute  percolate  before  evaporation.  The  present  Pharmacopoeia  directs 
two  parts  of  alcohol  and  three  parts  of  water,  and  the  Philadelphia 
College  of  Pharmacy  recommended  the  same  menstruum,  with  ten 
per  cent,  of  glycerin  in  the  first  one  hundred  parts.  A  sample  thus 
prepared  in  January,  1880,  now  contains  only  a  very  slight  precipitate, 
and  is  in  all  other  respects  in  most  excellent  condition ;  two  other 
samples  were  recently  prepared,  one  the  same  as  the  above,  and  the 
other  with  the  oflicinal  menstruum ;  the  first  has  undergone  no  change 
whatever,  the  second  contains  a  slight  flocculent  precipitate,  but  if  no 
further  change  occurs  it  will  be  evident  that  glycerin  serves  no  useful 
purpose  in  this  preparation. 
ExTRACTUM  Tritici  Fluidum. — Fluid  Extract  of  Triticum. — For 
this  newly-introduced  preparation  the  Pharmacopoeia  directs  one  hun- 
dred grammes  of  finely-cut  triticum,  to  be  percolated  with  boiling 
water  until  it  is  exhausted  ;  the  percolate  is  to  be  evaporated  to 
eighty  cubic  centimeters,  to  which  is  to  be  added  twenty  cubic 
centimeters  of  alcohol,  and  then  after  being  set  aside  for  forty- 
eight  hours,  it  is  to  be  filtered,  and  to  the  filtrate  is  added  enough  of  a 
mixture  of  four  parts  of  water  and  one  part  of  alcohol  to  make  the 
fluid  extract  measure  one  hundred  cubic  centimeters.    The  Phila-
