PHARMACEUTICAL  NOTES. 
(Contributed  by  the  School  of  Pharrnacy  of  Purdue  University.) 
Introduction. — Contributions  for  the  advancement  of  science 
may  be  expected  from  an  institution  engaged  in  purely  scientific  in- 
struction ;  and  a  school  devoted  to  pharmaceutical  education  should 
likewise  do  what  is  possible  to  advance  the  interests  of  the  profession 
by  investigating  the  character  of  the  drugs  supplied  in  trade,  the 
processes  best  adapted  for  their  preparation,  and  the  methods  of  test- 
ing their  genuineness  and  purity.  Pharmaceutical  students  should 
learn  their  own  responsibility  for  the  advancement  of  their  chosen 
profession,  and  should  be  taught  how  to  conduct  such  investigations 
as  may  be  within  their  reach.  Articles  not  otherwise  credited  are  by 
the  undersigned. 
The  following  notes  represent  an  effort  to  do  what  we  could.  As 
far  as  practicable  the  work  of  students  has  been  credited  to  their 
several  names ;  but  the  theses  have  been  freely  condensed  by  the 
compiler.  The  seven  members  of  our  first  graduating  class  are  all 
represented  by  name,  while  the  work  of  juniors  also  will  be  found 
under  "  Potassii  Bitartras." 
Some  remarks  upon  the  standard  of  purity  prescribed  for  "Potassii 
Nitras"  will  apply  to  many  other  salts. 
Hoping  to  continue  this  work  from  year  to  year,  the  Faculty  will 
gladly  receive  suggestions  from  any  persons  interested  in  pharmacy 
upon  such  topics  as  may  need  investigation.
