Delafond in the year 1845 first showed the vegetable rod-like 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, 
Pure 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.
