which each student was required to make thirty quantitative determinations in 

 alkahmetry and acidimetry. 



The assistant in chemistry gave a short course of lectures on blowpipe analy- 

 sis, and under his charge each student was required to make an analysis of twenty 

 different substances in the dry way. 



The class spent two hours a day either in attending lectures or in practical 

 laboratory work. The total number of students in these classes was forty-six. 



FALL TERM. 



Junior Class. — The Junior Class completed the study of cliemical physics, 

 and I am now delivering a course of lectures on meteorology. I have given two 

 evening lectures with illustrations on the subject of electricity. Total number 

 of students in attendance in this class is sixteen. 



Sojjhomore Class. — The Sophomore Class are engaged in qualitative chemical 

 analysis, spending three hours a day in laboratory work, each one making his 

 own investigation into the composition of unknown substances under the direc- 

 tion of the Professor and his assistants. The whole number of students in 

 analysis this term is thirty-eight. 



In addition to the regular students in the course, three resident graduates have 

 given their attention to higher chemistry, manipulation, etc. The total num- 

 ber of students that have received instruction in this department during the year 

 is seventy-one. 



OUTSIDE WORK. 



It is difficult for a teacher in a public institution to confine himself entirely to 

 class-room work. Tlie public claim (and justly) a certain amount of his time and 

 energy. The amount of this outside work should be considered in estimating a 

 teacher's work for the year. The public often pass lightly over what is really 

 one of the most laborious parts ot a teacher's work. While this is cheerfully 

 performed by the public-spirited teacher, it is none the less worh. 



Farmers'' Institutes. — I need not speak at length of the Farmers' Institutes 

 of 1876, for the history and results of these meetings are already before you in 

 the Eeport of your Board for 1875. Besides assisting in the organizing of these 

 Institutes, I attended and took part in the Institutes at Allegan, Decatur, 

 Adrian, and Coldwater. I also took part in an extra Institute at Ypsilanti. At 

 the request of this Board I have prepared and had printed a circular in regard 

 to the Institutes of 1877, and have sent copies of this circular to each member 

 of the Board. 



American Ifedical Association. — Having been appointed Chairman of tlio 

 Section of State Medicine and Public Hygiene in the American Medical Associa- 

 tion, I attended the meeting of that body in June at Philadelphia, and presided 

 at the meetings of the Section named. In preparing the work for that Section 

 much labor in the way of correspondence and circulars was involved, but as the 

 results of such work are for the benefit of the whole mass of the people, I felt 

 justified in devoting a part of my time to this work. As Chairman of the Sec- 

 tion, I gave a public address before the Association on The Two Great Natural 

 Purifiers, viz. : Air and Water. In the Section I read an extended report on 

 The Water Supply of Michigan, 



State Board of Health. — As member of the State Board of Health, I have 

 attended all its meetings except the one in Januar}-, from which I was absent 

 on account of the Farmers' Institutes, which occurred at the same time. I
