88 LIFE OF BENJAMIN SILLIMAN. 



of that office, and remained in the instruction and govern- 

 ment of the Institution until 1 853, when I fully resigned, 

 Laving made an overture for a resignation in 1850, which 

 was not accepted. During this period, on two different 

 occasions, I passed nearly two years abroad. By invitation 

 of the Corporation and Faculty of the College, I continued 

 to give the chemical lectures to the termination of the 

 course of 1853, and the lectures on mineralogy and geol- 

 ogy until the termination of the academic year of 1855. 

 My personal knowledge of Yale College has covered more 

 than sixty years, and therefore, as to historical facts, I may

In the first century of Yale College, a single room was 

 appropriated to apparatus in physics. It was in the old
