by a tick. The disease shows itself in cattle by fever, 

 bloody urine, dropsy, deficiency of blood, loss of appe- 

 tite, stoppage of milk secretion and rumination, rapid 

 wasting and death; post-mortems show the spleen 

 enlarged, as is the liver. The only effective treatment 

 is of the preventive character, by inoculation with the 

 blood serum of an affected animal. (Francis and Con-

Anthrax is a rapidly fatal disease of cattle and other

 all carcasses or sprinkle with quicklime, handle as little 

 as possible, as this disease is more or less deadly to the 

 human being, hence one should never hold a post-mor- 

 tem on such a case, neither should the animal be skinned; 

 tanners and wool sorters sometimes become infected with 

 this disease through hides and fleeces. 



Lumpy jaw (actinomycosis) is due to the invasion of 

 the tissues by the ray fungus. This disease is quite com- 

 mon in cattle, usually showing itself in those animals by 

 enlargements of the lower jaw, in the early stages the 

 lumps are quite movable, later on the jaw bone becomes 

 affected; occasionally the upper jaw is affected or the 

 tumors are found on the skin of the head and neck; may
