ATROPA  BELLADONNA,  OR  SCOPOLA  CARNIOLICA. 
By  A.  R.  L,.  Dohme  and  Hermann  Kngelhardt. 
(Read  by  Charles  Caspari,  Jr.) 
The  authors  said  that  according  to  the  medical  profession  the  scopola  alka- 
loids are  more  efficient  than  are  those  of  atropa.  Triplicate  assays  of  these 
drugs  were  made,  using  Professor  Keller's  method,  and  the  results  showed 
Scopola  to  be  richer  in  alkaloids  than  Atropa. 
NOTES  ON  INDIGENOUS  PLANTS. 
By  Caswell  A.  Mayo. 
The  writer  said  that  in  the  early  history  of  Virginia  frequent  allusions  were 
made  to  the  indigenous  drugs.  He  gave  a  number  of  extracts  from  the  writ- 
ing of  Colonel  William  Byrd,  Captain  John  Smith,  Hugh  Jones,  and  others  of 
the  early  Colonial  period,  stating  that  these  records  were  for  the  most  part  in 
such  form  as  not  to  be  available  for  the  uses  of  the  student  of  botanical 
history.

WHAT  REPRESENTATIVE  PHARMACISTS  AND  PHYSICIANS  THINK 
ABOUT  PLASTERS. 
By  Seward  W.  Williams. 
The  paper  embodied  a  classification  of  replies  to  queries  bearing  on  the 
question:  "  To  what  extent  are  official  plasters  employed  in  the  practice  of 
medicine  and  pharmacy  ? ' '  The  replies  were  from  members  of  the  American 
Medical  Association  and  the  American  Pharmaceutical  Association,  and  indi- 
cated that,  for  the  most  part,  the  official  plasters  are  being  superseded  by  the 
rubber-combination  plasters.

By  George  W.  Boyd. 
(Read  by  Charles  Caspari,  Jr.) 
The  author  commented  upon  the  unsatisfactory  character  of  the  compound 
spirit  of  ether  and  said  that  the  difference  in  names  leads  to  confusion. 
THE  NATURE  OF  COMMERCIAL  SANGUINARINE  NITRATE. 
BY  J.  O.  SCHLOTTERBECK. 
The  writer's  experiments  led  to  the  conclusion  that  the  so-called  sanguinarine 
of  the  market  is  largely  composed  of  chelerythrine.  He  therefore  thought 
that  the  matter  should  be  cleared  up  by  the  Pharmacopoeia.
