December,  1894.  Von  Prof.  Emer.  Dr.  G.  Dragendorff.    St.  Petersburg,  1895. 
In  this  Journae,  1885,  p.  318,  is  a  review  of  a  former  publication  of  this  kind, 
reporting  the  progress  of  the  Pharmaceutical  Institute  of  the  University  of 
Dorpat,  under  the  direction  of  Professor  Dragendorff,  from  1865  to  1885.  The 
present  pamphlet  of  23  pages  continues  that  account  down  to  the  close  of  1894, 
which  was  about  the  time  he  retired.  It  shows  an  increase  in  the  attendance  of 
students  much  greater  than  that  of  its  predecessor.  In  1885  the  annual  attend- 
ance of  pharmaceutical  and  medical  students  amounted  to  341,  and  in  1894, 
634.  During  this  time  the  number  of  pharmaceutical  students  has  more  than 
quadrupled,  while  the  number  of  medical  students  has  decreased  somewhat. 
A  concise  account  of  the  investigations  conducted  by  the  students  is  included, 
followed  by  a  list  of  the  dissertations  and  other  publications.
