 tered upon the idea with unusual vivacity, and even expressed joy 

 that he had at last discovered the means of distracting his mind. 

 But all of a sudden he completely collapsed, and with a sad look 

 and groan he uttered : "It will be of no use ; it will remind me 

 even more irrepressibly of my severe loss ; for, whenever I had 

 found anything new or interesting during my researches, I would

 last years of his life, and with failing health, he would not refuse 

 his professional services to those who claimed them even at late 

 hours of the night. He often said to me, ''How can I refuse to 

 go, when they send for me?"
