■Oct. 1901. Annual Report of the Director. 9 



Lecture Courses. — The usual two courses have been given, but 

 unfortunately a decrease in the attendance has to be noted. This 

 lack of interest may be accounted for by the fact that a casual review 

 of the syllabuses would indicate by the titles of the lectures more 

 technical discourses than had obtained in previous courses. Further- 

 more, the great increase in the number of lectures given by 

 different institutions in Chicago has probably tended to diminish the 

 interest in any course of free lectures. Following is a list of the lec- 

 tures given during the year:
