exhaustion and Inflammation of the visible mucous mem- 

 branes. Preventive measures are very important. Care- 

 ful nursing, comfortable quarters and light diet are about 

 as valuable as medicines. Counter irritants, stimulants 

 and tonics may be used to advantage in the convalescent 

 period. The bowels should be kept open at all times. 

 Pneumonia is generally associated with pleurisy, an in- 

 flammation of the serous membrane lining the chest 

 cavity. The causes, symptoms and treatment are similar 

 to those for pneumonia. 



Another disease of swine affecting primarily the res- 

 piratory organs, but often extending to other parts, such 

 as the intestines, brain and lymph glands, is tuberculosis. 



It is not very common in the South, but is probably 

 becoming more prevalent. The common source of in- 

 fection in swine is from cattle by way of the skim milk, 

 manure, or through the eating of offal from slaughtered 

 tubercular cattle. Pulmonary tuberculosis is accom- 

 panied by symptoms similar to those manifested in cases 

 of chronic bronchitis. Methods of possible infection and 

 predisposing causes should be removed, and all suspected 

 animals and those known to have the disease should be 

 isolated or destroyed. 



Swine plague is another disease of swine afifecting the 

 respirator}' system. It is often confused with both hog 

 cholera and pneumonia. It occurs in both chronic and 

 acute forms. The preventive treatment is about the same 

 as that employed in hog cholera and pneumonia. This 

 disease does not occur often in the southern states.
