The  reports  on  scientific  queries  being  called  for,  it  was 
found  that  Numbers  10,  11,  12,  27,  31,  33,  34,  39,  42,  43  and 
46  were  not  replied  to. 
Henry  W.  Lincoln,  of  Boston,  read  a  long  essay  on  query 
13,  relative  to  Oleum  Theobronwe,  illustrated  by  specimens  of 
the  fruit  and  oil,  pure  and  adulterated,  with  samples  of  choco- 
lates. 
Prof.  Wadgymar,  of  St.  Louis,  did  not  reply  to  query  21,  on 
Kicinus  communis,  but  offered  in  place  of  it  a  reply  to  query 
27  of  1865,  on  Hyosciarnia,  which  had  not  been  reported  on 
last  year,  owing  to  ill  health.  Professor  Bedford  read  this 
paper,  which  was  accepted,  and  referred  for  publication. 
Query  22,  on  the  physiological  properties  of  the  leaves  of 
Eicinus  communis,  was  continued  to  Mr.  Heydenreich,  of 
Brooklyn,  his  experiments  having  not  yet  been  completed. 
Query  26  was,  for  a  similar  reason,  continued  to  Mr.  Markoe. 
Query  45,  on  the  best  form  of  apparatus  for  making  pills, 
was  replied  to  by  Ferris  Bringhurst,  of  Wilmington,  Del.  In 
connection  with  this  subject,  the  author  called  the  attention  of  the 
Association  to  a  pill  machine  on  exhibition  by  Mr.  A  .H.  Wirz, 
of  Philadelphia.  Mr.  Bringhurst  also  alluded  to  the  great  con- 
venience of  a  tin  box  loaded  with  shot,  as  a  counterpoise  in 
shop  weighing ;  and  exhibited  a  bottle  for  keeping  volatile 
oils,  the  bottle  being  encased  with  tin,  some  filtering  paper  be* 
ing  placed  beneath  the  bottle,  to  absorb  the  oil  which  might 
escape  over  the  lip.  The  same  member  exhibited  a  copper 
funnel,  with  movable  conical  wire  frame,  for  facilitating  filtra- 
tion, the  whole  to  replace  glass  funnels  for  many  uses. 
A  general  discussion  ensued  on  filters  and  filtration. 
The  Executive  Committee  proposed  the  name  of  Edward  H. 
Heinitsh,  of  Columbia,  S.  C,  for  membership,  when  a  ballot 
was  ordered,  and  he  duly  elected. 
The  Business  Committee  presented  a  communication  from  the 
East  Biver  Medical  Association,  relative  to  physicians'  prescrip- 
tions, which,  from  the  lateness  of  the  session,  was,  by  motion  of 
Mr.  Tufts,  laid  over  as  unfinished  business  until  next  session. 
Mr.  Markoe  exhibited  a  model  of  a  powdering  mill,  on  a  new 
principle.
