generally  acceptable  and  satisfactory.  The  appointments,  however, 
according  to  the  by-laws,  were  confirmed  by  the  General  Com- 
mittee and  Board  of  Trustees.  Each  sub-committee  then  proceeded 
to  elect  its  chairman,  the  election  being  finally  approved  by  the 
General  Committee  and  Board  of  Trustees. 
Executive  Committee. — By  common  consent,  it  was  then  decided 
that  the  chairman  of  sub -committees  would  constitute  the  Executive 
Committee,  the  general  chairman  presiding  according  to  the  by- 
laws. This  plan  has  been  very  effective,  as  the  Executive  Com- 
mitte  has  thus  consisted  of  representatives  from  every  sub-com- 
mittee and  naturally,  being  chairman,  they  were  all  active  workers. 
Method  of  Revision. —The  following  plan  of  procedure  was  then 
adopted:  The  Sub-committee  on  Scope  decided  very  promptly 
upon  the  majority  of  the  substances  to  enter  the  new  Pharma- 
copoeia. This  list,  over  which  there  was  no  difference  of  opinion, 
was  immediately  placed  in  the  hands  of  the  other  sub-committees 
for  their  consideration,  while  the  Sub-committee  on  Scope  proceeded 
with  the  further  consideration  of  drugs,  chemicals  and  preparations, 
over  which  there  was  some  question  concerning  admission.  As 
these  were  decided  they  were  reported  to  the  Executive  Committee, 
with  the  vote  in  the  Sub-committee  on  Scope  and  finally,  if  ad- 
mitted, referred  to  the  proper  Sub-committee  for  revision.  As  a 
preparation,  drug  or  chemical,  or  possibly  a  process,  was  referred  to 
a  sub -committee,  the  chairman  was  given  entire  liberty  of  action 
and  two  different  methods  were  in  general  use,  depending  upon  the 
preference  of  the  presiding  officer.  In  one  instance,  the  chairman 
compiled  all  available  data  on  each  subject,  and  submitted  it  to  his 
sub-committee  for  their  consideration  and  comment.  Having  com- 
pleted this  step,  and  any  necessary  experiments  or  tests,  he  then 
prepared  a  tentative  text,  embodying  the  desired  changes,  as  indi- 
cated by  his  own  experience  and  experiments,  and  the  recom- 
mendations of  members  of  his  sub-committee.  The  text  was  then 
submitted  to  the  sub-committee  and  again  subject  to  their  criticism. 
When  finally  satisfactory  to  the  sub-committee,  the  revised  text 
was  sent  to  the  chairman  of  the  Executive  Committee  who  modified 
the  wording,  if  necessary,  to  bring  it  into  harmony  with  the  editorial 
style  decided  for  the  new  book,  and  then  submitted  it  to  the  Executive 
Committee  for  their  comment. 
The  other  plan  used  by  some  sub-committee  chairmen  was  to
