[The treatment referred to consists of simple astringent and antiseptic washes, borax given in the drinking water, or mixed with honey or treacle and smeared occasionally on the tongue. Washes of sodii hyposulphis or sulphis, or even weak solution of carbolic acid, may be used after the irritant cause has been removed. Vinegar or diluted mineral acids may be used alternately with decoctions of blackberry bark or other vegetable astringents. When there are symptoms of gastric disorder a laxative, followed by vegetable bitters and other tonics, may be prescribed. Foreign bodies—thorns, wire, etc.—fixed in the tongue, cheek, or palate should be searched for and removed at the first examination of the patient.] NECROSING STOMATITIS IN CALVES. =Definition.= This name is applied to a special stomatitis, which in very young animals produces superficial necrosis of more or less extensive areas of the buccal mucous membrane, and sometimes of subjacent parts. The disease, although somewhat rare in France, has been mentioned by Lafosse and well studied by Damman and Lenglen. =Causation.= Its cause is still imperfectly understood. Some regard it as a consequence of insufficient nourishment, of disturbance resulting from dentition, of general exhaustion, and of bad hygienic conditions. These explanations are scarcely sufficient, however, and at the present time there is a tendency to regard it as a complication of primary grave, debilitating diseases, like the diarrhœa of calves, omphalitis, omphalo-phlebitis, etc. Moussu has never seen it apart from omphalitis, and he considers the lesions due to the action of the bacillus of necrosis. Infection occurs through the umbilicus becoming soiled by contact with the litter. The early symptoms consist in loss of appetite, congestion of the mucous membranes, and salivation. Early examination of the buccal cavity reveals the presence everywhere, except on the palate, of whitish-grey or yellowish patches, whose aspect is markedly in contrast with that of neighbouring parts. These are fragments of the mucous membrane undergoing necrosis. They are numerous, are surrounded by a narrow inflamed zone, and may be from ½ inch to 1 inch in diameter. Necrosis advances rapidly, and extends throughout the thickness of the mucous membrane; the slough soon becomes delimited and separates. The odour of the mouth is then absolutely fœtid, and the saliva appears streaked with pus and blood. The ulcerations exhibit a livid base, and show no tendency to heal. Necrosis extends in depth, and affects the muscles, tendons, and even the periosteum and the bones. The teeth are frequently loosened. Grave complications, such as pharyngitis, broncho-pneumonia, infectious enteritis, and septicæmia soon appear, and the animals are carried off by septic infection and intoxication in a few days—at the longest in a week.
