President James C. Greenough. 



Sir : — The course of instruction given durinc: the past 

 year, in the chemical department, has been in the main the

 agriculture, will be taught hereafter in the second senior

The Senior, Junior and Sophomore classes have taken 

 part in the exercises. The Sophomore class has received 

 instruction during two terms in the chemistry of non-metallic 

 and metallic elements, with practical illustration of the best 

 modes for their recos^nition. The Junior class has been 

 engaged wuth practical chemical work in the laboratory, for 

 two terras in succession. During the first term they have 

 studied the chaiactcristics of the common metallic elements, 

 by ways of the blowpipe, and humid analysis. The second 

 term has been occupied with learning the properties of the 

 most important mineral acids and their principal combina-

The Senior class has devoted one term of laboratory work 

 to the examination of prominent products of various branches 

 of chemical industry, and of refuse material employed for 

 manurial purposes, besides analyzing commercial fertilizers,
