unimportant,  such  as  each  reader  would  readily  correct  when 
noticed,  and  a  list  of  errata  has  been  published  to  enable  the  pur- 
chasers of  the  first  edition  to  correct  them.  The  plates  have  at 
once  been  corrected  so  that  the  errors  are  eliminated  from  the  later 
copies. 
Since  the  publication  of  the  Pharmacopoeia  the  committee  of 
revision  has  not  been  idle.  Its  active  chairman,  Dr.  Charles  Rice, 
with  the  consent  of  all  of  the  members,  has  organized  "  Research  " 
committees  to  engage  in  preparatory  work  in  aid  of  the  next  revi- 
sion.   Thus  far,  four  such  committees  have  been  organized  : 
Research  Committee  A.  Subject,  The  feasibility  of  devising 
practical  methods  of  assay  for  drugs  containing  no  sharply  defined 
proximate  principles  capable  of  being  separated  in  a  sufficiently 
pure  state  (such  as  ergot,  digitalis,  rhubarb,  etc.). 
Chairman  :    Dr.  W.  M.  Mew. 
Research  Committee  B.  Subject,  Revision  of  the  description  and 
tests  of  inorganic  chemicals,  including  salts  of  inorganic  bases  with 
organic  acids.  Revision  of  the  volumetric  assays  of  the  U.  S.  P. 
Study  of  the  proper  limits  of  purity  or  strength  of  chemicals,  now 
official,  or  likely  to  become  so  hereafter. 
Chairman  :    Dr.  Charles  O.  Curtman. 
Research  Committee  C.  Subject,  Inquiry  into  the  feasibility  of 
incorporating  into  the  U.  S.  P.  methods  of  identifying  such  drugs  as 
may  be  found  to  permit  of  it,  in  a  powdered  condition. 
Chairman  :    Dr.  H.  H.  Rusby. 
Research  Committee  D.    Subject,  Revision  of  the  description 
and  tests  of  organic  chemicals. 
Chairman  :    Dr.  Charles  Rice. 
The  members  of  these  committees  are  to  be  selected  hereafter 
and  other  committees  are  to  be  organized  as  occasion  may  arise. 
The  results  of  the  researches  of  these  committees  are  to  be  reported 
to  the  whole  committee  of  revision  and  may  be  published  by  the 
authors,  provided  they  state  that  the  papers  are  reports  of  U.  S.  P. 
Research  Committees.  This  will  secure  to  the  profession  an  early 
knowledge  of  these  researches  and  an  opportunity  to  repeat  the 
experiments  and  verify  or  controvert  them. 
In  conclusion  the  undersigned  would  urge  this  association  to  take 
early  action  in  considering  all  matters  connected  with  the  next  revi- 
sion of  the  U.  S.  Pharmacopoeia.    Neither  the  pharmaceutical  nor
