 not cease to be a considerable draught upon his 

 time. 



With the condition of the departments of knowl-

 every reason to be gratified. Among the pleasing 

 occurrences in the latter years of his life, was the 

 liberal endowment of the Scientific School, in the 

 origin and progress of which he had been intimately 

 concerned. 



Previously to 1842, there had been no means pro- 

 vided for the instruction of advanced students in the 

 physical sciences, either at Yale College or at any 

 of the other Institutions in the United States. Up to 

 that time the academical students had been instructed 

 in chemistry almost exclusively by lectures. Pro- 

 fessor Silliman had been long in the habit of receiv- 

 ing into his laboratory a very limited number of per- 

 sons who were fitting themselves to become teachers 

 of the departments of science under his care. This 

 number rarely exceeded two or three persons at one 

 time. There were no recitations ; the art of manipu- 

 lation, the management of chemical processes, and

 chief subjects of attention. Among these gentlemen

 these departments. In 1842, Mr. Silliman, Jr., being 

 then professional assistant to his father, made arrange-
