APPOINTED PROFESSOR: STUDIES IN PHILADELPHIA. 105 



The temptation was strong to attend other courses of 

 lectures, and I attempted it ; but soon found that I must 

 confine my attention mainly to my own pursuits, and there-

 the class, but that for myself I had other occupations on 

 the day proposed, and if that were to be the time, I must 

 lose the instruction. After a moment's pause, the Pro-
