REPORT OF THE DEPARTMENT OF ZOOLOGY AND PHYSIOLOGY. 



To the President:

 of Zoology and Physiology for the year ending June 30, 1902 : 



The schedule of classes for the year was as follows :

 al, required, 47 students. Anatomy and Physiology for sophomore

 Geology for senior women, elective, 4 students. Anatomy and Physiology 

 for sophomore agricultural, required, 40 students. Anatomy and Physi- 

 ology for sophomore women, required, 30 students. Physical Geography 

 for sub-freshman 5-year mechanicals, required, 62 students. Entomology 

 for fruit course specials, 6 students. Total for term, 165 students. 



Spring Term. — Entomology for senior agricultural, elective, 13 stu- 

 dents, Entomology for junior horticultural (horticulture 6a), 10 students.

TEACHING FORCE AND EQUIPMENT. 



At the close of last year Mr. William T. Shaw, instructor in zoology, 

 resigned in order to accept a position in the Iowa Agricultural College, 

 and his place was filled by the election of Mr. Jesse J. Myers, a graduate 

 of the University of Illinois, who came well recommended and has justi- 

 fied all that was said of him. Mr. Myers gives his whole time to the work 

 of this department : Mr. R. H. Pettit, instructor in zoology, has continued 

 to give about half his time to this work, the remainder being given to 

 entomological work for the Experiment Station. Thus for the first time 

 in eight years the force of the department has been fairly sufficient for the 

 work expected of it. The class work has never been so satisfactory as 

 during the past year, and it has been possible, moreover, to carry out 

 some needed improvements in the laboratory and museum. The entire 

 supply of anatomical and zoological teaching material has been over- 

 hauled, sorted and arranged for convenient reference, while some of the 

 gaps in the illustrative series in the museum have been filled. Numerous 

 lantern slides have been prepared as well as a large number of micro- 

 scopic mounts for the laboratory classes. In addition to the regular 

 classes instruction has been given to a few students in taxidermy and 

 methods of preserving specimens, but such work has been entirely volun- 

 tary on the part of the students and the number necessarily has been small. 



COLLEGE EXTENSION WORK. 



In the way of College Extension Work the Department has not been idle. 

 Besides answering hundreds of letters from farmers, school teachers and 

 others in regard to all manner of things biological and geological, the
