8 DISCOVERY OH. 



Davy might have made a fortune by his discovery, 

 by taking out a patent for the invention of the safety- 

 lamp, but he refused to do so. One of his friends, Mr. 

 John Buddie, who urged him on one occasion to secure 

 this recompense for his investigations and their result, 

 said : "I felt that he did not contemplate any pecuniary 

 reward ; and in a private conversation I remonstrated 

 with him on the subject. I said ' You might as well

 institute of which he is the head, although he is 

 relatively a poor man. The founder of the prize, M. 

 Osiris, one day asked him why he had given the money 

 to the institute. "All that I am," replied Dr. Roux, 

 " I owe to the Pasteur Institute, for all my experiments 

 and discoveries have been made there. Besides, the 

 Institute is very poor, for we have no income except 

 what we make by the sale of serums, and though that 

 brings in enough to keep the establishment going, some 

 fresh remedy may any day be discovered, in which case 

 I fear the Institute would have to close its doors for 

 want of funds." The millionaire said nothing at the 

 time, but at his death, it was found that he had left 

 the bulk of his wealth, amounting to nearly one and a 

 quarter million pounds, to the Pasteur Institute, as a
