strengths  of  menstruum  were  experimented  with,  but  in  each  case  the 
product  separated  into  two  clear  layers,  which  became  milky  when 
shaken  together. 
ExTRACTUM  Scutellaria  Fi^vibvm.— Fluid  Extract  of  Scutel- 
laria.— This  is  one  of  the  newly-introduced  fluid  extracts;  the  Phar- 
macopoeia directs  a  menstruum  composed  of  one  part  of  alcohol  and 
two  parts  of  water ;  the  Philadelphia  College  of  Pharmacy  recom- 
mended diluted  alcohol ;  a  sample  thus  prepared  in  December,  1879, 
now  has  some  oily  matter  on  the  sides  of  the  bottle  above  the  fluid 
extract,  and  also  contains  quite  a  large  precipitate,  which  is  divided 
into  two  equal  layers,  the  lower  of  a  bright  green,  and  the  upper  of 
a  dull  brown  color,  the  fluid  extract  otherwise  is  in  rather  bad  con- 
dition ;  diluted  alcohol  is  evidently  not  suited  for  this  preparation,  but 
the  remedy  would  seem  to  be  more  in  the  direction  of  a  stronger  men- 
struum than  a  weaker  one,  such  as  the  officinal.
