LOUIS PASTEUP. 

 N'evee has the world been called upon to 

 lament the death of one whose life was so 

 full of gifts to humanity as that of Louis 

 Pasteur. Others have lived with equal 

 genius, others there have been whose influ- 

 ence upon thought has been equal or greater. 

 Others have achieved an equal reputation 

 from achievements of various kinds; but no 

 other man in the history of the world has 

 given to mankind so many valuable gifts as 

 those which have come from the labors of 

 Pasteur. That Pasteur possessed great ge- 

 nius is manifest, but yet it was not wholly 

 genius that explains his marked preemi- 

 nence, for a certain modicum must be attrib- 

 uted to the timeliness of his work. His 

 greatness w^as due in a measure to the fact 

 that early in life he had the fortune to have 

 presented to his attention and the wisdom 

 to seize upon great problems for solution. 

 He early seized for his own an almost new 

 field of research and brought to this new 

 field an equipment entirely different from 

 that which any other scientist had pos- 

 sessed. Pasteur is regarded as the father 

 of modern bacteriology, but we must re- 

 member that he was not a pioneer in these 

 lines of work. There was hardly a prob- 

 lem that he studied which had not been al- 

 ready recognized, and even studied to a 

 greater or less extent by his predecessors ; 

 but at the same time there was not a single 

 problem which Pasteur undertook to solve
