mended  to  prepare  it  by  decocting  the  drug  two  or  three  times  in  water, 
evaporating  and  adding  honey,  and  that  the  entire  root  was  used.  Pro- 
fessor Maisch  thought  that  the  bark  was  probably  the  efficacious  part  of  the 
drug,  since  the  woody  part  of  the  root  was  nearly  tasteless.  Mr.  Schrceter 
stated  that  the  whole  root  had  been  employed  in  his  experiments.  Profes- 
sor Maisch  in  reply  to  a  query,  stated  that  the  Hydrangea  arborescens  was 
indigenous  to  this  country  and  grew  wild  in  the  neighborhood  of  Philadel- 
phia ;  but  that  the  ornamental  garden  flower  was  the  Hydrangea  hortensis, 
a  Chinese  plant,  the  natural  color  of  whose  flowers  was  pink,  the  bluish 
shade  frequently  seen  being  due  to  the  absorption  of  iron  in  the  soil.  The 
paper  of  Mr.  Schrceter  was  illustrated  with  a  number  of  samples,  showing 
the  reactions  of  hydrangin  with  different  tests. 
The  third  paper  was  by  Mr.  F.  B.  Quackenbush,  of  the  present  senior 
class  upon  Asdepias  Cornuti  and  A.tuberosa;  and  Dr.  Lowe  read  a  short  paper 
upon  immature  cubebs.  All  these  papers  were  referred  to  the  Publication 
Committee.  In  answer  to  a  question  Professor  Maisch  stated  that  the  ovary 
of  the  cubeb  flower  was  at  first  sessile,  but  later  on,  probably  after  fertiliza- 
tion produced  the  so-called  stalk. 
Dr.  Lowe  stated  that  he  was  not  yet  prepared  to  make  a  report  upon  the 
question  referred  to  him  last  month;  relative  to  the  quality  of  the  tar  now 
supplied,  but  some  enquiries  had  been  made  and  enough  had  been  learned 
to  show  that  nearly  all  that  is  offered  to  the  trade  is  a  mixture  of  wood  tar 
with  coal  tar. 
There  being  no  further  business  a  motion  to  adjourn  was  put  and  carried.

The  Alumni  Association  of  the  Philadelphia  College  of  Pharmacy  will  cele- 
brate their  25th  anniversary  by  holding  in  the  College  Hall  an  exhibition 
representing  the  progress  made  in  pharmacy,  and  allied  arts  and  sciences, 
by  its  members.  The  exhibition  will  be  held  on  the  13th,  14th  and  15th  of 
March,  during  the  day  and  evening,  from  10  A.  M.  to  10  P.  M.,  and  from 
the  number  of  graduates  and  members  who  have  already  engaged  space 
there  will  certainly  be  an  interesting  exhibition.  It  is  also  the  intention  to 
place  upon  the  tables  many  objects  illustrating  the  pharmacy  of  the  past.

mained uncorrected  in  proofreading  of  his  paper  published  in  our  February 
number.  By  substituting  the  word  millimeters  for  centimeters  on  page  74, 
and  the  designation  mm.  for  cm.  referring  to  the  illustrations  on  page  75,  the 
dimensions  will  be  more  correctly  indicated. 
Mr.  Claassen  also  states,  that  it  will  be  found  advantageous  in  many  cases 
to  again  fold  the  narrow  strip  (indicated  in  the  figures  by  dotted  lines)  by 
bringing  its  lower  end,  commencing  at  the  angle,  over  to  the  inner  crease, 
thus  forming  a  small  triangle  ;  and  in  case  the  neck  of  the  funnel  should  be
