 ANOTHER VIEW OF THE NORWEGIAN FLAT-BREAD BAKERY

 the malady. 



At that time the world did not know 

 that infectious diseases were caused by 

 germs. A little later the science of bac- 

 teriology began to develop, and the great 

 French savant Pasteur finally succeeded 

 in demonstrating that anthrax fever is 

 caused by a definite germ. After deter- 

 mining the cause of the disease, he un- 

 dertook to work out the problem of com- 

 batting it. 



He found that the germ of anthrax 

 fever, when cultivated in chicken broth 



for several generations, loses its ability 

 to produce the disease. Not only this — 

 he proved that when this bacillus loses its 

 ability to produce disease, it gains a new 

 quality, that of rendering animals immune 

 from the attacks of uncultivated bacilli. 

 With these facts in hand he announced 

 that he could render sheep and cattle im- 

 mune against anthrax by inoculation. 



ONE OF THE MOST DRAMATIC SPECTACEES 

 OF HISTORY

 was greeted by a storm of derision on
