surface  of  the  ammonium  hydroxid  solution.  Add  20  mils  of  0.1  N  silver 
nitrate  solution  to  the  distillate,  set  aside  over  night,  heat  to  boiling  on  a  water 
bath  (in  order  to  agglomerate  the  silver  sulphid),  cool,  make  up  to  100  mils 
with  water,  and  filter.  Acidify  50  mils  of  the  filtrate  with  about  5  mils  of 
concentrated  nitric  acid  and  titrate  with  0.1  N  ammonium  thiocyanate,  using 
5  mils  of  10  per  cent,  ferric  ammonium  sulphate  solution  for  an  indicator. 
Each  mil  of  0.1  N  silver  nitrate  consumed  equals  0.004956  grain  of  allyliso- 
thiocyanate.  (Service  and  Regulatory  Announcements,  U.  S.  Dept.  of

Stramonium  Leaves  Substitute. — Examination  of  samples 
of  importations  of  "  stramonium  leaves  "  has  disclosed  that  Xan- 
thium  strumarium  L.  has  been  substituted  in  some  instances  for  the 
true  material.  The  examination  further  showed  the  absence  of  the 
alkaloids  characteristic  of  the  drug  of  the  genuine  stramonium 
leaves,  Datura  stramonium  L.,  official  in  the  United  States  Phar- 
macopoeia. The  department  will  recommend  the  exclusion  from  the 
United  States  of  any  shipment  labeled  "  stramonium  leaves "  but 
consisting  wholly  or  in  part  of  Xanthium  strumarium.  (Service

PHILADELPHIA  COLLEGE  OF  PHARMACY. 
Minutes  of  the  Semi-annual  Meeting. 
The  semi-annual  meeting  of  the  Philadelphia  College  of  Phar- 
macy was  held  September  24,  1917,  at  4  P.  M.  The  President, 
Howard  B.  French,  presiding.  The  minutes  of  the  quarterly  meet- 
ing held  June  25  were  read  and  approved.  The  minutes  of  the 
Board  of  Trustees  for  June  were  read  by  the  Registrar,  J.  S.  Beetem, 
and  approved. 
The  report  of  the  Committee  on  Nominations  was  read  and  or- 
dered entered  and  filed.  Mr.  George  M.  Beringer  for  the  delegates 
to  the  Conference  of  Pharmaceutical  Faculties  held  at  Indianapolis, 
August,  1917,  reported  verbally.  President  Lyman's  address  was 
of  great  interest ;  higher  standards  for  pharmacy  were  largely  dwelt 
upon.  Four  years'  high-school  course  was  made  a  requirement  for 
college  entrance  from  1923.  The  Conference  suggested  that  teach- 
ers in  colleges  of  pharmacy  should  be  required  to  carry  on  a  certain 
amount  of  research  work  and  to  prepare  one  or  two  papers  each
