A HISTORY OF SCIENCE 



for this attempted conquest, where the brilliant assist- 

 ants he had gathered about him, and their successors 

 in turn, might take a share in this great struggle, un- 

 hampered by the material drawbacks which so often 

 confront the would-be worker in science. 



He desired also that the institution should be a cen- 

 tre of education along the lines of its work, adding thus 

 an indirect influence to the score of its direct achieve- 

 ments. In both these regards the institution has 

 been and continues to be worthy of its founder. The 

 Pasteur Institute is in effect a school of bacteriology, 

 where each of the professors is at once a teacher and a 

 brilliant investigator. The chief courses of instruction 

 consist of two series each year of lectures and labora- 

 tory demonstrations on topics within the field of bac- 

 teriology. These courses, at which all the regular staff 

 of the institution assist more or less, are open to phy- 

 sicians and other competent students regardless of na- 

 tionality, and they suffice to inculcate the principles of 

 bacteriology to a large band of seekers each year. 



But more important, perhaps, than this form of edu- 

 cational influence is the impetus given by the institute 

 to the researches of a small, select band of investigators 

 who have taken up bacteriology for a life work, and 

 who come here to perfect themselves in the final nice- 

 ties of the technique of a most difficult profession. 

 Thus such men as Calmette, the discoverer of the serum 

 treatment of serpent-poisoning, and Yersin, famous for 

 his researches in the prevention and cure of cholera 

 by inoculation, are "graduates" of the Pasteur In- 

 stitute. Indeed, almost all the chief laborers in this 

 field in the world to-day, including the directors of
