PHARMACEUTICAL  BACTERIOLOGY. . 
By  Albert  Schneider. 
The  author  said  that  students  of  pharmacy  should  be  taught  the  relation  of 
bacteria  to  the  deterioration  of  the  various  drugs  and  preparations,  and  that  they 
should  possess  such  a  knowledge  of  the  subject  as  will  enable  them  to  examine 
various  commercial  products.  On  the  other  hand,  an  endeavor  should  not 
be  made  to  teach  students  of  pharmacy  bacteriological  diagnosis. 
THE  ALKALOIDS  OF  SAMBUCUS  CANADENSIS. 
By  W,  C.  Alpers. 
The  presence  of  a  hitherto  undiscovered  alkaloid  in  the  bark  of  this  plant 
was  reported  by  the  author.  The  principle  responded  to  various  of  the  alka- 
loidal  reagents  and  appeared  to  possess  the  characteristics  of  coniine.  It  was  not, 
however,  submitted  to  ultimate  analysis.  The  bark  was  the  only  part  of  the 
plant  examined,  and  it  was  recommended  to  use  the  fresh  article,  as  the  odor 
entirely  disappeared  on  keeping.

EXAMINATION  OF  URINE,  SPUTUM  AND  BLOOD. 
By  F.  W.  F.  Stedem. 
The  author  gave  some  general  directions  for  the  work  indicated  by  the  above 
title,  and  mentioned  a  number  of  reference  books  which  he  had  found  useful. 
A  lengthy  paper,  answering  various  queries  proposed  by  the  Scientific  Sec- 
tion and  reporting  on  the  examination  of  numerous  drugs  and  preparations  of 
the  market,  was  read  by  E.  L.  Patch,  and  was  referred  to  the  Committee  on 
Revision  of  the  U.S.P. 
WILD  CHERRY  BARK  AND  ITS  PREPARATIONS. 
By  A.  B.  Stevens. 
During  the  course  of  his  work  the  writer  made  over  250  estimations.  Ex- 
periments were  made  to  ascertain  which  portion  of  bark  contained  the  gluco- 
side,  and  it  was  found  that  the  inner  layer  contained  practically  all  of  this  prin- 
ciple, not  much  being  found  in  the  middle  layer  and  none  in  the  outer  layer. 
The  fact  was  also  revealed  that,  there  being  more  of  the  green  layer  of  bark  on 
the  north  side  of  the  tree,  more  of  the  glucoside  was  found  in  this  portion  than 
that  on  the  south  side.  Experiments  with  the  fluid  extract  showed  the  phar- 
macopceial  method  to  be  unsatisfactory,  in  that  the  amount  of  menstruum  is 
too  small  and  also  owing  to  the  fact  that  evaporation  does  not  leave  a  trace  of 
acid.  With  regard  to  the  syrup  the  author  said  that  maceration  should  be  car- 
ried on  in  the  percolator  in  which  the  drug  is  to  be  percolated,  and  percolated 
directly  upon  the  sugar.
