The following changes, substitntions aiul addilioiis were made in the 

 scheduled work in physics during the ])ast year: 



(a) Physics Id — Two hours laboratory work per week was sub- 

 stituted for a one hour quiz period per week. This has 

 proved a wise change. 



(b) Physics J{C which has previously dealt with the theory of 

 internal combustion engines, automobiles and farm light- 

 ing plants, was changed to a course in Telephonology this 

 year to meet the needs of the forestry ''rangers." Several 

 trips were made by the class to nearby exchanges, starting 

 with the simple manual switchboard (e. g., Haslett, 

 Okemos, etc.) and finally making a careful study of the 

 more complex types of switc]d)oards, such as the one at 

 the Bell Telephone Company's Central Station at Lansing. 

 I wish to express my gratitude to the Bell Company for the 

 assistance rendered us. 



(c) Physics 5, a required live hour course for Freshman Vet- 

 erinary students, spring term, Avas added this year at 

 the request of the Dean of Veterinary Science. This neces- 

 sitatecl the working out of a special course suited to the 

 needs of medical students — much abridged. 



The total enrollment in the Physics department for the year 191G-17, 

 was 889. The tabulation below shows the courses taught, and the num- 

 ber of students enrolled in each. Each course is a five-credit subject, 

 excepting Physics 4a, 4b and 4c which are three credit subjects.
