nal Aqua  0  amphorae  ? 
Answered  by  Mr.  G.  F.  H.  Markoe,  of  Boston. 
This  elicited  considerable  remark,  in  which  the  formula  of  the 
new  British  Pharmacopoeia  was  alluded  to. 
Query  6th. — Does  the  Aqueous  Extract  prepared  from  Jalap,  that  has 
been  previously  exhausted  by  alcoholic  process,  have  any  medicinal  prop- 
erties, or  does  the  alcoholic  extract  of  Jalap  fully  represent  its  virtues  ? 
Answered  by  Mr.  A.  B.  Taylor,  of  Philadelphia. 
Query  7th. — Does  the  volatile  oil  of  Matico  possess  the  power  of  stop- 
ping haemorrhage,  or  does  that  property  of  the  drug  reside  in  some  other 
ingredient  or  in  the  physical  structure  of  the  leaf? 
Answered  by  a  note  from  Mr.  Higgins,  who  was  unable  to  pro- 
cure proper  materials  to  operate  with. 
Query  8th. — On  the  pharmaceutist  as  a  merchant,  and  on  commercial 
education  in  relation  to  the  successful  prosecution  of  the  pharmaceutic 
art  ? 
Answered  by  Mr.  F.  Stearns,  of  Detroit. 
Query  9th. — Stramonium  is  abundant  in  the  United  States,  and  its 
alkaloid  Daturia  is  alleged  to  be  identical  with  Atropia  in  Belladonna. 
If  this  be  true,  in  what  relative  proportions  do  these  plants  contain 
this  principle,  and  why  may  not  Stramonium  be  used  as  a  source  of 
Atropia  ? 
No  reply  was  received  from  Mr.  F.  F.  Mayer,  by  whom  it  was 
accepted. 
Query  10th. — It  is  now  known  that  Storax  is  a  production  of 
Liquidamb  ;r  Orientale,  a  tree  closely  resembling  L.  styraciflua  of  the 
United  States.  It  is  also  well  known  that  our  indigenous  Liquidambar 
yields  in  warm  latitudes  a  balsamic  exudation,  analogous  to  storax  in 
odor  and  to  tolu  in  consistence  ;  and  contains  cinnamic  and  benzoic  acids. 
Query. — Will  this  tree  yield  a  product  identical,  or  nearly  so,  with  com- 
mercial storax,  if  it  is  treated  in  the  same  manner  ? 
Partially  answered  by  Professor  Procter,  who  asked  to  have  it 
continued  to  him  another  year. 
On  motion  of  Mr.  A.  B.  Taylor  it  is  ordered,  that  in  all  cases, 
where  Queries  were  not  answered  or  heard  from  at  the  time  of 
meeting,  they  be  continued  another  year  to  the  same  person.
