DISEASES OF THE DIGESTIVE ORGANS. 19 



ACTINOMYCOSIS OF THE JAWBONES (BIG JAW OE LUMPY JAW). 



[See Actinomycosis p. 430.] 

 INFLAMMATION OF MUCOUS MEMBRANE OF MOUTH (STOMATITIS). 



The membrane of the mouth may be become inflamed by cattle eating 

 some irritating substance or plant, or little vesicles may form in the 

 mouths of calves when they are affected with indigestion, constitu- 

 ting what is termed aphtha. 



Symptoms. — The saliva dribbles from the mouth, and when the 

 mouth is examined the surface of the tongue and other parts will 

 appear red and inflamed. When young animals are affected with 

 the form of disease termed aphtha, small red elevations will be observed 

 on the tongue and other parts of the mouth, having little white points 

 on their centers, which consist of the epithelium of the mucous mem- 

 brane raised into vesicles. These white patches are succeeded by 

 ulcerated surfaces, which are caused by the shedding of the white 

 patches of epithelium. 



Treatment. — When there is merely a reddened and inflamed condi- 

 tion of the mucous membrane of the mouth, it will suffice to syringe 

 it out several times a day with 4 ounces of the following solution : 

 Alum, 1 ounce; water, 2 pints. When the edges of the tongue and 

 other parts of the mouth are studded with ulcers, these should be 

 painted over once a day until the affected surface is healed, with the 

 following solution : Permanganate of potash, 20 grains; water, 1 ounce. 

 When indigestion is associated with an ulcerated condition of the 

 mouth, separate treatment is required,

DISEASES OB 1 THE PHARYNX AND GULLET. 



PHARYNGITIS (SORE THROAT). 



This is an inflammation of the mucous membrane lining the pharynx. 

 It is frequently associated with inflammatory diseases of the respira- 

 tory tract, such as laryngitis and bronchitis or pleurisy. 



Symptoms. — The muzzle is dry and the saliva dribbles from the cor- 

 ners of the mouth; the animal either does not swallow or swallows with 

 difficulty, and holds its neck in a stiff, straight position, moving it as 

 little as possible. The eyelids are half closed, the white of the eye is 

 bloodshot, and the animal occasionally grinds its teeth. After masti-
