involve the feet. Foot-rot and ergotism are not attended by 

 stomatitis. Necrotic stomatitis of calves is seen only in 

 very young animals, does not involve the external skin and 

 the lesions are characterized by a necrosis of the mucous 

 membrane of the mouth. The feet are not attacked. 



Prognosis. — The prognosis is good; only in aggravated 

 cases are losses recorded from secondary infection. 



Treatment. — The principal indication in treating this 

 disorder is to remove the cattle from the infested pastures, 

 best placing them in a barnyard and feeding soft feeds. 

 The animals should be given constant access to fresh water. 

 It is recommended to place in the water borax (1 oz. to 1 

 gal. of water). In range cattle four ounces of crude carbolic 

 acid may be mixed with twelve quarts of barrel salt, the 

 cattle being permitted to lick this at will. The foot lesions 

 are treated according to the general principles of surgery. 

 As a rule the animals rapidly recover when they are removed 

 from the infested pasture. 



Phlegmonous Stomatitis. — ^Definition. — A purulent infec- 

 tion of the mucous membrane and submucous connective 

 tissue of the mouth. 



Etiology. — Phlegmonous stomatitis is the result of infection 

 with pus-producing bacteria or fungi. It may be either 

 primary or secondary. The primary form results from trau- 

 matism. The ingestion of food containing caterpillars, aphis, 

 irritant insects or molds may also produce it. Irritant 

 drugs or chemicals which gain access to the mouth, caustics, 

 acids, strong carbolic acid, croton oil, chloral hydrate crystals, 

 etc., are causes. Secondary phlegmonous stomatitis may be 

 a symptom of strangles, anthrax, purpura hemorrhagica, and 

 malignant head catarrh of the ox. 



Symptoms. — ^The symptoms are those of a severe inflam- 

 mation of tbe buccal mucous membrane involving principally 

 the' tongue and lips. In some instances the lips are so swollen 

 that the mouth cannot be closed. The tongue may be swollen 

 so that imprints of the incisor teeth are left upon it. There 

 is salivation and the patient is unable to eat. Fever may be 

 present. The process may involve the pharynx leading to 

 dysphagia and nasal discharge. The sublingual and para-
