Delafond in the year 1845 first showed the vegetable rod-Hke bodies or 

 bacilli anthracis peculiar to anthrax. In our last article on glanders we 

 spoke of the so-called germs, and showed of what great importance they 

 were in many diseases. They gain entrance into the body by direct 

 inoculation, or through the mouth, or through the air passages. These 

 bacilli of anthrax (of which we append drawings) are now almost universally 

 ^believed to be the actual exciting cause of anthrax. Either these bacilli 

 themselves or their spores are always present in enormous numbers in the 

 blood of animals suffering from anthrax fever or splenic fever. The bacilli 

 may be separated and washed with distilled water, alcohol, and ether, and 

 dried, yet they still cause anthrax fever when introduced into animals. 

 I'ure cultivation of this germ through fifty generations may be made with 

 the same result. The germ always gives rise to anthrax fever, and never to 

 any other. Therefore in it we recognise the direct cause of the malady.
