TEACHING. 



All of the courses announced in the Program of Courses of Instruction 

 have been given and have been well attended. 



At the beginning of the present college year, the work of the depart- 

 ment was expanded by the addition of a course in General Biology. 

 Professor James George Needham, who for several years had held a 

 privately-supported Chair of Limnology in this University, was added 

 to the staff as Assistant Professor of Limnology and General Biology. 

 That the establishment of this course in General Biology met a pressing 

 need was shown by the fact that, although provision was made for 

 300 students, we are forced to refuse admission to 85 other students. To 

 aid in carrying on the work in General Biology, Mr. Robert Matheson 

 and Air. John Thomas Lloyd, both graduates of this University, were 

 appointed Assistants in Biology. 



In addition to the new course in General Biology, two new courses have 

 been given by Assistant Professor W. A. Riley, one during the first half- 

 year on Animal Parasites and Parasitism and one during the second 

 half-year on the Relations of Insects to Disease. 



The sum of the nmnbers of students attending courses in this depart- 

 ment during the past year is 443. Some students attended more than one 

 course. The number of different individuals were as follows : 



Undergraduates 384 



Graduates 17 



Total 401 



INVESTIGATION. 



There was published during the year a Text Book of General Biology 

 by Assistant Professor Needham. This book has been so well received 

 that it has been necessary to publish a second edition. 



A manual of the Arachnida of North America upon which the writer 

 has been engaged for ten years is now nearly completed. He hopes to 

 have it ready for publication in the course of a few months. The results 

 of an investigation of the morphology of the palpi of male spiders, made
