766 DISEASES OF CATTLE. 



Care must be taken to avoid a rush of air into the chest. A 

 probe or piece of iron must be used to remove obstructive plugs of 

 lymph, which sometimes enter the canula. A solution of carbolic 

 acid, 1 dram to 10 oz. of blood-warm water, is frequently used to 

 rinse the cavity. 



SPORADIC PEEITRO-PNEITMOMIA. 



This is often confounded with the epizootic form, but it is a dif- 

 ferent disease, and not contagious. 



Symptoms. — A shivering fit will 

 be noticed, and soon after the se- 

 cretion of milk is arrested. Acute 

 symptoms quickly succeed, and 

 pulse becomes rapid, firm, and 

 hard, the friction sound of pleurisy

gives pain. The bowels are con- 

 stipated, urine scanty and high-colored, and there is a discharge from 

 the eyes and nose. The membranes are injected, the legs, horns, 

 and ears are cold, the coat stares, and the skin becomes harsh and 

 dry. (See Fig. 1004.) 



Treatment. — Let a correct diagnosis be made, to distinguish the 

 nature of the disease. The, treatment must be prompt, skillful, and 

 energetic. The measures directed for pneumonia and pleurisy are 

 applicable here. Diuretics, stimulants, and tonics are called for, 

 and blisters should be used, under the same precautions. 



ASTHMA-EMPHYSEMA. 



This is an inflammation of the muscular coat of the bronchial 

 tubes, and is very apt to mislead the inexperienced. Few animals 

 present a more pitiable appearance than cows suffering from this 

 affliction. The symptoms are mainly negative. In fact, the animal 

 is usually past recovery when the definite symptoms of, this disease 

 have appeared. 



The first thing to attract notice is a diminution of milk. The 

 udder appears small, soft, and flaccid, and the teats are long and 

 pendulous. There is considerable wasting of the flesh, a staring 

 coat and dirty skin. The animal eats little, and rumination is irreg- 

 ular. The head is carried low, the back arched, and tender under 

 pressure, and weakness is evident in walking. 



In the second stage there is increased debility, very irregular
