The  loss  of  alkaloid  in  the  official  method  is  26*8  per  cent.,  but  by  this  pro- 
cess it  is  reduced  to  87  per  cent. 
TINCTURE  OF  LOBELIA. 
BY  J.  F.  I/IVERSEEGE. 
In  the  British  Pharmacopoeia  it  is  stated  that  lobelia  should  be  reduced  to 
No.  40  powder  for  preparing  the  tincture,  but  the  author  found  that  only  about 
40  per  cent,  could  be  made  to  pass  through  a  No.  40  sieve,  working  on  the 
small  scale,  and  with  a  pestle  and  mortar.  In  view,  therefore,  of  the  fact  that 
pharmacists  might  be  in  doubt  whether,  under  the  circumstances,  they  should 
use  the  specified  quantity  of  the  drug  powdered  as  finely  as  possible,  or  take  a 
larger  quantity  and  make  up  the  full  weight  from  the  powder  that  passes 
through  the  sieve,  he  investigated  the  point  whether  the  latter  would  yield 
stronger  tincture  or  not.  As  a  result  of  experiments,  it  was  found  that  a  tinct- 
ure prepared  from  the  fine  powder  contained  rather  more  than  one  and  a  half 
times  as  much  extractive  and  alkaloid  as  one  prepared  from  the  stalks  left  on 
the  sieve.  It  was  suggested,  therefore,  that  the  official  instructions  should  be 
so  far  modified  as  to  permit  of  the  tincture  being  prepared  by  pharmacists,  on 
the  small  scale,  with  ordinary  appliances.  The  same  suggestion  was  also 
applied  to  the  formulas  of  the  other  B.  P.  tinctures. 
GLYCERIN  TINCTURE  OF  CINCHONA. 
By  Frederick  Davis. 
The  purport  of  this  paper  was  merely  to  show  by  experimental  data  that  a 
better  tincture  of  cinchona  may  be  prepared  by  using  glycerin  with  alcohol  for 
the  exhaustion  of  the  bark  than  by  employing  alcohol  alone. 
The  reading  of  papers  having  been  disposed  of,  after  occupying  nearly 
four  sessions,  the  question  of  next  year's  meeting  was  brought  up,  and  it  was 
decided  that  the  Conference  should  meet  at  Liverpool  in  1896.  The  following 
officers  were  then  elected  : 
President,  William  Martindale;  Vice-presidents,  Michael  Carteighe,  J.  Laid- 
law  Ewing,  W.  Hayes  and  M.  Conroy;  Treasurer,  John  Moss;  Honorary  General 
Secretaries,  W.  A.  H.  Naylor  and  F.  Randsom;  Honorary  Local  Secretary,  T.  H. 
Wardleworth;  Executive  Committee,  F.  C.  J.  Bird,  E.  H.  Farr,  E.  M.  Holmes, 
Stewart. Hardwick,  W.  F.  Wells,  Edmund  White,  R.  Wright,  George  Coull  and 
J.  Smith.  
AMERICAN  PHARMACEUTICAL  ASSOCIATION. 
The  forty-third  annual  meeting  of  the  American  Pharmaceutical  Association 
was  held  in  Denver,  Col.,  from  Wednesday,  August  14th,  to  Wednesday,  August 
2i,  1895. 
On  Tuesday,  August  13th,  members  of  the  organization  and  their  accompany- 
ing friends  began  to  arrive  in  Denver  from  all  parts  of  the  United  States,  with 
the  exception  of  the  Pacific  Coast  ;  this  section  being  poorly  represented,  pro- 
bably because  of  the  inability  of  the  Transportation  Committee  to  secure  a 
reduction  in  railroad  rates. 
En  route  to  their  destination,  the  several  parties  of  delegates,  which  traveled 
mostly  by  special  train,  were  tendered  entertainments  by  the  pharmacists  of  the 
cities  through  which  the  route  lay.    Notable  among  the  special  attentions
