ECONOMY  IN  THE  USE  OF  ALCOHOL  IN  PERCOLATION. 
On  the  preparation  and  use  of  Resin  of  Podophyllum. 
By  Edward  R.  Squibb,  M.  D. 
The  following  paper  is  an  addition  to  the  series  published 
during  the  past  few  years,  as  researches  upon  the  process  of 
percolation  as  applicable  to  practical  pharmacy,  and  with  especial 
reference  to  economy  in  the  use  of  alcohol ;  and  it  adds  one  more 
typical  drug  to  those  which  have  been  specially  and  individually 
investigated  in  this  direction. 
The  officinal  (U.  S.  P.)  formula  for  Resin  of  Podophyllum*  is

so  commonly  refuse  to  this  substance  its  proper  and  correct  name,  and 
adhere  to  the  inaccurate  and  otherwise  objectionable  name  of  Podophil- 
lin,  and  this  latter  name  is  particularly  objectionable  and  vulgar  when 
pronounced  with  the  accent  on  the  final  syllable.  Beside,  this  name  and 
its  peculiar  pronunciation  belong  where  they  originated,  namely,  to  a 
substance  of  au  almost  proprietary  character  as  made,  sold  and  used  by 
the  sect  of  so-called  "Eclectics,"  by  processes  not  publicly  known,  and 
probably  differing  in  the  hands  of  different  makers.  Those  accustomed 
to,  and  desiring  to  use  this  article  are  quite  right  in  adhering  to  its  name 
and  the  pronunciation  of  it,  but  those  who  would  use  the  officinal  sub- 
stance had  better  use  the  officinal  title.  The  termination  in  has  long 
been  applied  to  certain  proximate  principles  of  a  neuter  character  and
