menstruum  by  percolation,  being  left  in  the  marc,  the  same  can  be 
expressed,  distilled,  or  displaced  by  water. 
In  my  experience  the  percolation  process,  and  especially  the 
improved  macero-percolation  method  of  our  U.S.P.  VIII,  although 
the  same  cannot  be  used  for  the  exhaustion  of  all  drugs,  decreases 
the  labor  and  saves  time  and  is  a  scientific  method  par  excellence. 
When  properly  carried  on  all  the  advantages  of  maceration  are 
obtained  and  furthermore  it  is  superior  to  maceration,  inasmuch  as 
no  strong  menstruum  is  retained  in  the  marc. 
In  conclusion  I  want  to  state  that,  although  percolation  has  been 
originated  in  a  foreign  country,  American  pharmacists  have  greatly 
perfected  this  process  and  American  pharmacy  can  justly  be  proud 
of  it.

MAHLON  N.  KLINE. 
Mahlon  N.  Kline,  President  of  the  Smith,  Kline  &  French  Co., 
wholesale  druggists,  Philadelphia,  died  suddenly  of  heart  failure 
on  Saturday  evening,  November  27,  while  attending  a  meeting 
of  the  Brotherhood  of  St.  Andrew  at  the  Church  of  the  Saviour, 
Philadelphia.  Mr.  Kline  was  so  long  and  so  intimately  associated 
with  the  drug  trade,  both  wholesale  and  retail,  and  did  such 
excellent  work  in  connection  with  drug  and  pharmaceutical  matters 
that  his  death  will  be  felt  as  a  distinct  loss  to  the  industry. 
Of  all  his  other  affiliations  it  may  truly  be  said  that  none  were 
of  more  deep  concern  to  him  that  his  relations  with  the  Philadelphia 
College  of  Pharmacy,  and  his  work  as  a  member  and  officer  reflects 
credit  alike  on  his  ability  and  loyalty  to  its  interests.  He  was 
elected  an  active  member  in  1886  and  a  member  of  its  Board  of 
Trustees  in  1897,  of  which  latter  body  he  became  Chairman  in 
1901.    He  was  elected  First  Vice-president  of  the  College  in  1905,
