 cember 27, 1822, one who was to become one of 

 the foremost scientists of this century, which is so 

 great in science, and who has by his admirable 

 labors added to the glory of his country and de-

 of Dole! 



Amid all the praises which Pasteur received 

 from his grateful countrymen, there were several 

 attacks which lent at least variety to his eventful

 of great service to bacteriology, because it makes 

 it possible to isolate particular strains of bacteria 

 from an originally mixed culture. At the medical 

 congress held at Geneva, in which Pasteur defended 

 his position, Koch failed to reply to the challenge
