LOUIS PASTEUR 



the militant attack which has a method in doubting and 

 whose rule of conduct has the motto " More light." 



It is a pleasure once more to acknowledge the helpfulness 

 of the aid given me by Messrs. Chamberland and Roux 

 during the studies I have just recorded. I wish also to 

 acknowledge the great assistance of M. Doleris.
