sively  introduced  into  the  United  States  ;  can  their  flowers,  as  has  been 
repeatedly  asserted,  be  made  available  for  destroying  insects,  and  may 
they  be  regarded  as  a  substitute  for  the  so-called  "  Persian  Insect 
Powder,"  which  is  derived  from  the  nearly  allied  genus  Pyrethrum  ? 
Partially  answered  by  Mr.  G.  F.  H.  Markoe,  who  presented 
some  dried  specimens  of  the  plant.  Mr.  Markoe  asked  to  have 
the  same  subject  continued  to  him  another  year,  which  was 
granted. 
Query  22d. — Pumpkin  seeds  have  acquired  some  reputation  as  a  reme- 
dy in  taenia.  Does  their  curative  power  reside  solely  in  a  fixed  oil? — if 
so,  what  is  the  best  process  of  extracting  it,  and  of  dispensing  it  for  in- 
ternal use  ? 
Mr.  C.  A.  Tufts,  of  Dover,  N.  H.,  who  accepted  this  query, 
informed  the  Association  that  he  had  had  no  opportunity  of  try- 
ing any  experiments,  and  asked  to  have  the  subject  continued, 
which  was  granted. 
Query  23d. — An  essay  on  gas-heating  apparatus  adapted  to  the  various 
purposes  of  the  apothecary,  so  as  %o  enable  him  to  conduct  his  processes 
in  or  near  the  shop ;  which  shall  combine  efficiency  with  economy ;  illus- 
trated by  figures  or  specimens. 
Mr.  Bedford,  of  New  York,  asked  to  have  this  subject  con- 
tinued to  him,  as  he  had  been  unable  to  finish  his  investigations 
in  time  for  this  meeting. 
Query  24th. — Valerianate  of  Ammonia.  The  crystalline  salt  made  by 
the  process  of  B.  J.  Crew  is  apt  to  have  adhering  valerianic  acid,  which 
renders  it  disagreeably  odorous  and  moist,  What  is  the  best  means  of 
obtaining  a  dry,  neutral  salt  ? 
No  answer  was  received  from  Mr.  Bullock,  to  whom  it  was 
referred,  in  reply  to  this  question,  but  he  explained  through  Mr. 
Bedford  why  he  had  not  answered  it.    This  query  was  dropped. 
Query  25th. — What  is  the  best  formula  for  Elixir  of  Valerianate  of 
Ammonia,  which  shall  be  nearly  free  from  valerianic  odor  and  elegantly 
aromatized  ? 
Continued  to  Mr.  J.  Roberts,  of  Baltimore,  by  whom  it  was 
accepted. 
Query  26th. — Is  there  a  reliable  test  for  the  active  resin  from  Cannabis 
sativa  of  the  East  Indies,  whereby  the  genuineness  of  Extract  of  Indian 
Hemp  may  be  satisfactorily  and  easily  ascertained  by  the  pharmaceutist  ? 
Replied  to  by  Mr.  Procter,  at  length,  in  a  paper  read  by  him.
