ON  FLUID  EXTRACTS  OF  ERYTHROXYLON  AND 
CINCHONA. 
By  Professor  Joseph  P.  Remington,  Ph.M. 
From  the  Proceedings  of  the  American  Pharmaceutical  Association^  July  16. 
During  the  past  winter  the  writer  has  been  engaged  in  examining 
practically  the  various  menstrua  for  the  official  fluid  extracts  and 
the  results  of  these  labors  may  be  summarized  as  follows  :  The  mens- 
truum for  Fluid  Extract  of  Erythroxylon  in  the  present  Pharmaco- 
poeia contains  more  alcohol  than  is  necessary ;  the  best  results  were 
obtained  from  menstrua  made  by  mixing  one  part  of  alcohol  with 
two  parts  of  water,  both  by  volume.  This  made  a  fluid  extract  in 
which  the  very  slight  precipitate  was  found-to  be  of  inert  matter. 
In  the  case  of  the  Fluid  Extract  of  Cinchona,  the  menstruum  which 
yields  the  best  results  was  one  which  was  composed  of  four  parts 
of  alcohol  and  one  of  glycerin,  both  by  volume,  finishing  the  per- 
colation with  a  mixture  of  four  parts  alcohol  and  one  of  water,  both 
by  volume. 
This  menstruum  yields  a  fluid  extract,  which  though  exposed  for 
six  months  to  a  lower  temperature  than  that  prevailing  at  the  time 
of  its  percolation,  has  not  produced  any  precipitate  whatever.

This  shrub  is  commonly  called  "  stagger  bush."  It  belongs  to 
the  natural  order  of  Ericaceae  and  grows  in  low,  sandy  places, 
throughout  New  Jersey  and  southward  near  the  coast.  The  leaves 
are  said  to  be  poisonous  to  lambs  and  calves. 
A  proximate  analysis  of  the  leaves  yielded  the  following  results:
