 leading men in the professional and intellectual life of Philadelphia, 

 and he could not have been elected and reelected as their presiding 

 officer if he had not been a man of great accomplishment, of sound 

 learning, and of upright character. 



Prof. John Bassett Moore, of New York, read a paper on " Con-
