within  described  Process  of  producing  Concentrated  Fluid  Extracts,  by 
bringing  the  crude  drug  gradually  in  contact  with  the  desired  measure  of 
Liquid  to  be  represented  by  the  extract,  and  exposing  it  after  each  appli- 
cation of  liquid,  to  a  heavy  pressure — substantially  as  set  forth  ;  where- 
by extracts  of  uniform  strength  can  be  made,  and  both  heat  and  evapo- 
ration avoided.

[Note. — The  process  of  Mr.  Thomas  noticed  above,  merits  the  careful 
attention  of  our  Colleges  of  Pharmacy,  as  guardians  of  the  interests  of 
medicine  and  pharmacy.  If  the  claims  made  for  the  process  are  true, 
within  practicable  limits,  we  esteem  it  of  great  value,  for  the  reasons  given 
in  the  paper  by  the  author ;  but  if  it  be  not  true, — or  at  least  not  true  in 
practice — that  a  drug  may  be  thus  exhausted  of  its  valuable  medicinal  con- 
stituents, measures  should  be  taken  by  our  Colleges  to  prevent  the  inno- 
vation from  being  recognized  as  a  proper  and  efficient  method  ;  at  least 
so  far  as  relates  to  the  officinal  fluid  extracts.  It  is  the  interest  of  the  in- 
ventor, therefore,  to  submit  his  process  as  early  as  practicable  to  a  com- 
mittee of  pharmaceutists,  that  its  claims  may  be  tested.  Mr.  Thomas  is 
a  graduate  in  Pharmacy,  and  has  had  considerable  practical  experience 
in  making  pharmaceutical  preparations. — Ed.  Am.  Jour.  Pharm.]
