principles he inculcated, not only in science but in daily life, 

 as a man and a citizen, still mould the thoughts and feelings of 

 his friends and students. His science is better today, not only 

 by what he did, but still more by the influence he exerted and 

 the high ideal of character he left behind him. This is a 

 precious heritage which can never be lost.
