I 2 MEMORIAL OF JOSEPH HENRY. 



late to choose. < >ne result of clue deliberation was that he rarely 

 had to change his mind. When he had taken his course, he held 

 Id it. His patience and kindness under demands upon his. time 

 were something wonderful. Some men are thus patient from easy 

 good-nature; Henry was so from principle. A noticeable part of 

 the Secretary's correspondence was with a class of men — mure 

 numerous than would be supposed — who thought they had discov- 

 ered new laws of nature or new applications of them, and who 

 appealed to him to make their discoveries known. The Secretary 

 never returned a curt answer to such appeals or inquiries, whether 

 made personally or by letter. Many are the hours which lie would 

 conscientiously devote to such paradoxical schemes — sometimes of 

 wonderful ingenuity — and to the dictation of elaborate replies to 

 them. Detecting far down in the man's mind the germs of the 

 fallacy which had misled him, he would spare no pains to present 

 it and its consequences so plainly to his bewildered correspondent 

 that he could find his own way out of it ; while at the same time he 

 awarded credit and encouragement for whatever was true, probable, 

 or ingenious. 



Although of sensitive spirit and with a just sense of what was 

 due to himself, Professor 1 1 enry kept free from controversy. Once 

 he took up the pen, not because his discoveries were set at naught, 

 but because his veracity was impliedly assailed. His dignified 

 recital of undeniable facts ( in his Annual Report for 1857 ) was all 

 that was necessary, and not even a word of indignant comment was 

 added. 



He left his scientific work to form its part of the history of science 

 and to be judged by scientific men. The empiric lie once senten- 

 tiously defined to be "one who appeals his cause to an incompetent 

 tribunal." He never courted publicity; not from fastidious dislike, 

 still less from disdain of well-earned popular applause, but simply 

 because he never thought of it.
