Powdered  Medicinal  Extracts. 
Having  recently  enlarged  and  made  valuable  improvements  in  our  appa- 
ratus for  the  preparation  of  Powdered  Medicinal  Extracts,  we  respectfully 
ask  the  attention  of  Pharmacists  to  the  following  features  of  this  line  of 
pharmaceutical  specialties : 
1st.  The  solid  extracts  are  prepared  from  strictly  pure  drags  by  reperco 
lation,  and  only  the  concentrated  tinctures  are  used  for  evaporation. 
2d.  Each  officinal  extract  is  reduced  to  a  pilular  consistence  and  assayed 
for  the  percentage  of  water  contained  therein. 
3d.  The  pilular  extracts  are  exsiccated  in  thin  layers  at  a  temperature 
not  exceeding  140°  F. ;  and  special  precautions  are  exercised  with  those 
extracts  having  volatile  alkaloids,  or  active  principles  liable  to  dissociation 
by  exposure  to  prolonged  and  high  temperatures. 
4th.  The  loss  of  water  in  drying  of  pilular  extracts,  as  found  by  accurate 
assay,  is  compensated  by  the  addition  of  sugar  of  milk. 
5th.  Our  Powdered  Medicinal  Extracts  are  standardized  in  accordance 
with  the  strength  of  the  pilular  extracts  of  the  U.  S.  Pharmacopoeia,  and 
may  be  prescribed  in  precisely  tlie  same  doses. 
Gtli.  Every  package  emanating  from  our  Laboratory  is  labeled  so  that 
the  weight  of  the  crude  drug  represented  by  each  grain  of  the  powdered 
extract  may  be  seen  at  a  glance. 
Having  Originated  this  Class  cf  Pins  Prescription  Preparations^ 
end  knowing  the 'marked  fa  v^or  they  have  met  with  in  the  dispensing  de- 
l)artnienls  of  our  best  Pharmacists,  we  do  not  deem  it  necessary  to  extol 
their  merits  on  the  score  of  convenience  or  reliability.
