FORMULAE  FOR  THE  FLUID  EXTRACTS  IN  REFERENCE  TO 
THEIR  MORE  GENERAL  ADOPTION  IN  THE 
NEXT  PHARMACOPEIA. 
By  William  Procter,  Jr. 
(From  the  Proceedings  of  the  American  Pharmaceutical  Association,  Boston,  1859.) 
Having  accepted  at  the  annual  meeting  of  the  Association 
for  1858  the  subject  of  Improved  Formulae  for  the  Fluid  Ex- 
tracts, I  have  occupied  no  inconsiderable  portion  of  time  in 
carrying  on  the  investigations  required  in  giving  a  rational  so- 
lution to  the  questions  involved. 
After  some  reflection  it  was  determined  to  consider  in  groups 
the  several  drugs  appropriate  for  fluid  extracts,  the  generic 
character  of  which  was  to  be  derived  from  an  analogy  of  com- 
position or  of  behaviour  with  solvents,  by  which  the  same  pro- 
cess could  be  employed  for  each  member  of  a  group  ;  leaving 
all  those  drugs  which  possessed  some  peculiarity  of  constitution, 
rendering  it  necessary,  to  be  treated  by  special  processes. 
In  the  formulae  adopted,  it  has  not  been  designed  to  retain  in 
solution  all  the  matter  dissolved  by  the  menstruum  from  each 
drug,  as  suggested  by  some  ;  nor  to  reject  all  not  usefully  medi- 
cinal as  sought  by  others  ;  but  to  extract  as  far  as  possible  all 
the  valuable  ingredients,  and  to  condense  them  into  the  required
