nients of necrotic tissue and parts of food stuffs. In these cases 

 there is fever, listlessness, and indican appears in the urine. 



Course and Prognosis. The primary form of phlegmonous 

 stomatitis generally takes a favorable course. If there is no 

 necrosis of tissue and no abscess formation, complete recovery 

 usually takes place within two or three weeks; even in the 

 severest cases recovery may occur under the proper surgical 

 treatment. Exceptionally, however, the inflammatory process 

 spreads to the larynx, the posterior wall of the pharynx and 

 along the trachea, which then usually leads to an unfavoral)le 

 termination. The latter also occurs in secondary stomatitis, 

 especially if it occurs in connection with anthrax, hemorrhagic 

 septicemia or with other malignant affections. 



Treatment. If the inflammation has been caused by nox- 

 ious food, a change of the latter and of pasture must be in- 

 stituted. Besides, irrigations and mouth washes, as generally 

 used in stomatitis, are indicated; purulent and ichorous inflam- 

 mation requires proper surgical interference.

Stomatitis Gangraenosa Agnorum. Gangrenous Stomatitis of 

 Lambs. Riolta repeatedly has observed a severe epizootic disease of 

 young lam])S characterized l)y the appearance of vesicles up to the size 

 of a copper cent, with thickened margins. Most of the sick animals die 

 within a few days, and the post-mortem exaniination, aside from the 

 lesions of the month, always showed tnbercledike foci in the liver. In 

 these foci was found the bacterium subtile agnorum which produced 

 ulcers on the mucosa on being inoculated into the buccal cavity of 

 healthy animals. (Rivolta, Giorn. di Anat. fisiol. e pathol. 1883-78.) 



6. Ulcerative Inflammation of the Buccal Cavity. Stomatitis 



ulcerosa. 



{Mundfaeule [German] ; Stomacace.) 



Ulcerative stomatitis is especially a disease of carnivora, 

 consisting in an acute inflammation of the g-ums, which soon 

 leads to necrosis and ulcerative destruction. 



Severe forms of stomatitis of herbivora caused by spoiled food, in- 

 cluding aphthous stomatitis, are included in this affection by some 

 authors (Friedberger & Frohner, Gips, Cadeac). But their clinical pic- 

 ture is so different from that of stomatitis ulcerosa, that such a classifi- 

 cation does not appear justified. 



Etiology. The disease generally occurs among highly 

 bred pet dogs and cats, especially among weakly and anemic
