SEMI-CENTENITIAL  ANNIVEESAKY 
OF  THE 
PHILADELPHIA  COLLEGE  OE  PHARMACY. 
At  the  College  Hall,  February  23d,  1871. 
At  the  meeting  of  the  Board  of  Trustees,  held  on  Tuesday,  the  7th  of  Feb- 
ruary, a  committee  of  three,  consisting  of  Wm.  C.  Bakes,  James  T.  Shinn  and 
Thomas  S.  Wiegand,  were  appointed,  to  take  all  measures  necessary  for  cele- 
brating, in  a  suitable  manner,  the  approaching  fiftieth  anniversary  of  the  first 
meeting  of  the  College,  at  the  Hall  on  the  23d  instant. 
In  pursuance  of  this  duty,  the  Committee  issued  tickets  of  invitation  to  a 
large  number  beside  the  members,  including  several  pharmaceutists  in  other 
cities. 
On  the  23d  of  February,  at  7^  P.  M.,  the  members  and  invited  guests  gath- 
ered, to  the  number  of  tv^o  hundred  and  fifty,  in  the  lecture-room,  second  story. 
On  the  tables  a  number  of  objects,  interesting  for  their  antiquity  and  calcu- 
lated to  show  a  contrast  with  similar  articles  of  the  present  day,  were  arranged. 
Among  them  an  old  rose-water  still  and  an  exhausting  apparatus,  the  modern 
elastic  clyster  apparatus,  with  the  old  pipe-and-bladder  arrangement,  old  chemi- 
cals, labels  and  books,  with  quite  a  display  of  the  best  chemicals  of  the  present 
day  from  the  laboratory  of  liosengarten  &  Sons.  It  was  pleasant  to  observe 
so  many  friends,  whose  interest  in  the  Institution  had  brought  them  to  the 
meeting.  Among  them  we  observed  Prof.  Moore,  Mr.  Thompson  and  Mr. 
Sharp,  of  Baltimore,  Mr.  Bedford,  of  New  York,  Mr.  Heinitsh,  of  Lancaster, 
and  Mr.  Lemberger,  of  Lebanon,  Pa.  Prominent  among  the  medical  gentlemen 
present,  were  Professors  Rogers  and  Leidy,  of  the  University  of  Pennsylvania, 
and  Professors  Gross  and  Rand,  of  the  Jefferson  College  ;  Dr.  W.  L.  Atlee  and 
Dr.  Ruscheuberger,  U.  S.  N.,  of  Philadelphia;  Prof.  Carson,  Prof.  Wood  and 
the  venerable  Prof.  Sam.uel  Jackson,  all  ex-professors  of  the  College,  were  pre- 
vented from  coming.  After  more  than  half  an  hour  spent  in  conversational  in- 
tercourse. President  Dillwyn  Parrish  called  the  meeting  to  order  in  a  few 
remarks,  and  invited  Peter  Williamson,  Esq.,  who  officiated  at  the  initial  meet- 
ing as  its  secretary,  fifty  years  ago,  to  preside.  Mr,  Williamson,  in  taking  the 
chair,  addressed  the  meeting  as  follows  : — 
"  Gentlemen  :  I  return  you  my  thanks  for  this  expression  of  your  desire  that 
I  should  preside  on  this  interesting  occasion — an  occasion,  gentlemen,  which, 
with  its  pleasant  memories,  is  not  unmingled  with  its  thoughts  of  sadness.  These 
naturally  force  themselves  upon  me  as  I  look  around  and  see  but  few  of  those
