history of the science; and no student could come in contact with 

 this serene and impartial mind without feeling profoundly its influence 

 in all his future studies of nature. 



In his personal character the same great qualities were apparent. 

 Unassuming in manner, genial and kindly in his intercourse with his 

 fellow-men, never showing impatience or irritation, devoid of personal 

 ambition of the baser sort or of the slightest desire to exalt himself, 

 he went far toward realizing the ideal of the unselfish, Christian 

 gentleman. In the minds of those who knew him, the greatness of 

 his intellectual achievements will never overshadow the beauty and 



dignity of his life.
