Indeed,  in  both  France  and  England,  the  recognition  of  phar- 
macists as  investigators  has  been  notably  greater  than  in  any  other 
country.  The  finest  chemical  laboratory  in  London,  namely,  that 
of  the  Imperial  College  of  Science  and  Technology,  had  as  its  first 
professor  of  chemistry,  one  -who  had  the  responsibility  of  con- 
structing the  newly  established  laboratory,  the  late  Sir  William 
Tilden,  who  began  as  an  apothecary,  and  for  many  years  was  con- 
nected with  the  chemical  laboratory  of  the  Pharmaceutical  Society 
of  Great  Britain.  He  published,  in  1916,  a  most  interesting  and 
valuable  book  covering  the  whole  range  of  chemical  activity,  the 
title  of  which  is  "Chemical  Discovery  and  Invention  in  the  Twen- 
tieth Century,"  which  book  is  one  of  the  most  suggestive  and 
readable  books  to  those  desiring  to  get  the  survey  of  the  broad 
scope  of  chemistry  and  its  applications  that  can  be  found  at  the 
present  time. 
With  this  survey  of  the  history  of  the  relations  of  pharmacists 
to  the  development  of  chemistry  in  earlier  times,  as  well  as  in 
recent  times  in  Europe,  we  can  now  come  to  consider  how  far  this 
relation  has  existed  in  this  country. 
Speaking  in  this  hall  of  the  Philadelphia  College  of  Pharmacy, 
and  in  connection  with  an  anniversary  of  the  founding  of  this 
institution,  it  seems  very  proper  for  us  to  consider  what  illustration 
of  our  subject  we  may  find  right  here  in  our  past  history  as  an 
Institution. 
Among  the  most  cherished  memories  of  this  Institution  are 
those  of  some  of  its  earliest  workers,  and  in  that  connection  we 
may  call  attention  to  the  fine  record  of  one  of  the  earlier  professors 
of  this  Institution,  namely  William  Procter,  Jr.,  who,  though  a  busy 
practicing  apothecary  and  a  teacher,  yet  found  time  to  carry  on 
many  investigations  which  advanced  chemical  knowledge  very 
notably.  The  value  of  these  was  also  recognized  in  much  wider 
circles,  and  gained  for  him  recognition  on  the  part  of  foreign  chemi- 
cal authorities.  His  discovery  of  the  composition  of  winter-green 
oil,  and  of  the  characters  of  the  salicylic  acid  derived  from  the 
same,  were  recognized  as  furnishing  the  earliest  knowledge  on  this 
subject. 
We  may  also  refer  to  the  long  series  of  contributions  to  chemi- 
cal knowledge  that  have  appeared  in  the  American  Journal  of 
Pharmacy  published  by  this  College  for  nearly  a  century  past. 
Coming  down  to  the  present  time,  we  still  have  very  active
