pletely broken clown that he was oUHfied to give up his regular work. 

 Then followed a weary chase after health. A journey to Europe 

 that summer did no good, nor was he more fortunate in the next winter 

 spent on lea\e of absence, or in the following sununer. In the autunui 

 of 1911, although no better, he took up his teaching again, for his 

 physicians decided that, if work were forbidden, the longing for it 

 would do him more harm than the work itself. Accordingly he began 

 to lecture in spite of agonizing attacks of pain, gi\ing us the spectacle 

 of duty triumphing over suffering, as before it had led him to disregard 

 his own ease and adxantage; but this heroism was in vam, the attacks 

 grew more frequent, until in the middle of the year lecturing became 

 impossible; but even then, as before, he filled up every cranny of his 

 life with work on his papers feeling that rest was impossible, while 

 anything remained undone, until death found him working at his 

 post on February 25, 1912. The faitlifulness, which had moulded 

 tvery action of his life, reached a fitting climax in the heroic devotion 

 to duty to its close.
