meeting  it  could  not  be  hoped  that  the  best  results  would  be  attained 
and  that  the  member  most  gifted  as  an  orator  would  be  able  to  exer- 
cise the  most  influence  over  a  large  number  of  uninformed  delegates. 
As -ah  illustration  of  the  desirability  of  preliminary  publication  of 
reports  of  subcommittees/ he  pointed  out  that  the  figures  placed  on 
the  board  relating  to  the  report  of  the  Subcommittee  on  Botany 
and  Pharmacognosy  were  as  new  to  him  as  to  the  majority  of  per- 
sons- present.  He -felt  that  the -publication  of  such  a  report  at  the 
time  would  no  doubt  have  been  an  incentive  for  work  along  this; 
particular  line  by  others.  Mr.  Wilbert  stated  that  he  did  not  hold 
the  Chairman  of  the  Revision  Committee  responsible  for  the  work  of 
the  committee,  and  that  after  all  was  said  and  done  a  good  Pharma- 
copoeia was  all  that  was  wanted. 
Professor  Kraemer  said  that  the  difficulty  connected  with  the 
publication  of  the  final  reports  of-  the  subcommittees  in  the  pharma- 
ceutical journals  could  be  obviated  by  having  the  matter  copy- 
righted in  advance. 
Mr.  Otto  Raubenheimer,  of  Brooklyn,  read  an  interesting  paper 
on  the  "  History  of  Maceration  and  Percolation." 
In  opening  the  discussion  on  this  paper  Mr.  Beringer  stated  that 
the  subject  of  maceration  had  been  brought  to  the  attention  of  the 
American  Pharmaceutical  Association  by  President  Oldberg  and  the 
method  recommended  as  having  advantages  over  that  of  percolation. 
Mr.  E.  H.  Gane,  of  New  York,  in  commenting  on  the  paper  said 
that  Mr.  Raubenheimer  had  covered  the  subject  quite  well.  He 
said  that  the  universal  adoption  of  the  method  of  percolation  showed 
its  superiority,  and  that  it  is  also  cheaper  when  applied  on  a  large 
scale. 
Mr.  Beringer  said  that  the  chapter  on  "  Percolation  "  in  the 
present  Pharmacopoeia  is  an  improvement  over  that  in  the  previous 
edition,  and  that  the  process  is  in  reality  a  maceration-percolation 
process.  He  stated  that  maceration  is  directed  in  the  preparation 
of  twenty  of  the  official  tinctures  which  are  mostly  resinous,  the  tinc- 
ture of  arnica  being  an  exception. 
Prof.  I.  V.  S.  Stanislaus  was  of  the  opinion  that  where  the  drug 
contains  less  than  50  per  cent,  of  extractive  percolation  should  be 
used,  but  in  the  case  of  larger  percentages  of  extractive  digestion  is 
to  be  preferred. 
Mr.  Wilbert  said  that  while  the  Brussels  Conference  adopted 
a  resolution  to  make  all  tinctures  of  potent  drugs  by  means  of  per-
