PROCEEDINGS  OF  THE 
of  Philadelphia,  not  being  reported  on,  were,  on  motion,  continued  to  him 
for  another  year. 
On  motion,  Dr.  Antisell,  of  Georgetown  College,  was  invited 
to  a  seat  in  the  Convention. 
15.  What  are  the  present  sources  of  senega,  spigelia,  and  other  prominent 
American  roots,  etc.,  as  supplied  by  commerce  ? 
Prof.  Guthrie,  to  whom  this  question  was  continued  last  year? 
stated  that  he  had  not  prepared  the  report,  and  asked  permission 
to  read  a  paper  on  another  subject  in  lieu  thereof,  which  was 
granted ;  and  it  was  referred  to  the  Executive  Committee  to 
publish  at  their  discretion. 
As  several  of  the  members  had  volunteer  papers  which  they 
were  anxious  to  read,  so  as  to  be  able  to  leave  the  city  before 
the  close  of  the  meeting,  precedence  was  granted  to  them  before 
the  remaining  regular  papers. 
Two  communications  from  Henry  A.  Tilden,  of  New  Lebanon, 
New  York,  were  presented  and  read  by  Dr.  Guthrie.  They  were 
referred  to  the  Executive  Committee  to  publish  at  their  discre- 
tion. 
Dr.  Henry  Thayer,  of  Cambridgeport,  Mass.,  was  then  invited 
to  read  his  papers  ;  the  first  on  concentrated  medicines,  and  the 
second  on  the  comparative  value  of  sugar  and  alcohol  as  preser- 
vative agents  in  fluid  extracts ;  both  of  which  were  accepted  and 
referred  for  publication. 
Dr.  Edward  R.  Squibb  having  prepared  a  volunteer  paper 
entitled  "  Suggestions  in  regard  to  the  revision  of  the  United 
States  Pharmacopoeia,"  he  was  invited  to  read  it,  which  he  con- 
tinued to  do  until  near  the  time  for  adjournment  arrived,  when  the 
remainder  was  left  till  the  morning  sitting. 
Dr.  Guthrie  offered  the  following  preamble  and  resolution, 
which  was  carried,  viz  : — 
Inasmuch  as  this  Association  has  heretofore  recognised  the 
law  of  Congress,  commonly  known  as  the  drug  law,  as  beneficial 
in  its  results,  and,  when  fully  carried  out,  a  protection  to  the  com- 
munity against  adulteration  and  sophistications,  and  believing 
that  law  to  be  imperfect  and  requiring  amendment,  therefore, 
"  Resolved,  That  the  memorial  prepared  by  a  committee  of 
this  Association  for  presentation  to  Congress,  be  also  placed  in
