PLATE XV. 



FIG. i. Bacillus anthracis. 



Bacteridie du charbon. 



Bacillus of splenic fever, woolsorters disease or 

 malignant pustule. 



The bacillus of anthrax grows very rapidly on sterilised 

 potato, especially when placed in the incubator at 

 the temperature of the blood. The growth forms a 

 creamy-yellow layer, with copious spore formation. 



FIG. 2. Bacterium indicum. 



Micrococcus indicus. 

 Bacillus indicus. 



Sterilised potato inoculated with a pure growth obtained 

 by successive cultivations. Unless the growth is 

 quite free from the presence of other bacteria, the 

 brilliant red colour is not obtained.
