=Symptoms.= The primary symptoms are usually represented by ptyalism and a certain difficulty in grasping food. In other cases the mucous membrane appears slightly dry for some time before salivation sets in. On introducing the fingers into the animal’s mouth some elevation of temperature may be noted, and on direct inspection the non-pigmented regions are seen to be abnormally vascular, a fact which has earned for this form of stomatitis the names of “erythematous” and “erysipelatous stomatitis.” If the stomatitis is due to local multiple irritation, such as results from spines and prickles in the food, the abnormal vascular appearance is confined to the neighbourhood of the abrasions or punctures, and the affected regions are of very varying size. In some cases, principally as a consequence of trifling local irritation and of burns of the first and second degree, blisters of varying size may develop and break, leaving behind ulcerations, which, however, always heal rapidly. The aphthous non-contagious stomatitis mentioned by certain authors seems most probably to pertain to this class. =Diagnosis.= The diagnosis is usually easy, and a little attention to the accompanying symptoms is sufficient to avoid confusion with the various forms of symptomatic stomatitis. =The prognosis= is favourable. =Treatment= is based on removal of the determining cause, if this can be recognised, withdrawal of rough forage, removal of sharp points on the teeth, extraction of stumps, etc. As a rule, recovery follows rapidly. It can be hastened by washing out the mouth directly, or by means of a syringe, with water containing honey, vinegar, decoctions of brier twigs, oak bark, barley or rice. This treatment is completed by supplying nourishing gruel and food demanding little mastication. CATARRHAL STOMATITIS IN SHEEP. “The more delicate buccal mucosa in these animals would render them more subject to inflammations, but this is more than counterbalanced by the mode of prehension of aliments, not by the tongue, but by the delicately-sensitive lips, and further by the daintiness and care with which these animals select their food. The =treatment= would not differ materially from that prescribed for the ox.” (Law’s “Veterinary Medicine,” Vol. II. p. 15.)
