If suppuration occurs it should be opened as soon as the pus can be definitely recognized, and the cavity treated antiseptically to prevent further local or general infection by the microbes. In deep abscess there is a certain danger of wounding blood vessels and salivary ducts, but this can be to a certain extent obviated by making an incision through the skin only and then boring the way into the abscess with a grooved director or the points of closed scissors. When the cavity is penetrated the pus will ooze out through the groove or between the scissor blades. When the pus has been evacuated the cavity should be washed out two or three times a day with mercuric chloride solution (1 : 1000), or permanganate of potash solution (1 : 100). When the gland becomes indurated and indolent seeming to merge into the chronic form it may be stimulated to a healthier action by a cantharides blister, or it may be subjected to daily massage, or to a daily current of electricity for ten or fifteen minutes. If the inflammation is slight or unrecognizable, the surface of the gland may be daily painted with tincture of iodine, and iodide of potassium maybe given internally, in daily doses of ½ to 1 drachm. Gangrene, the result of septic microbes, a weak system or too severe treatment, may be met by astringent and antiseptic agents locally, and by tonics, stimulants and a generous diet internally. In =cattle= the disease usually responds readily to local antiseptics, and stimulating germicidal embrocations. Camphorated spirit, alone or combined with tincture of iodine; cantharides ointment with carbolic acid; and camphor and phenol may be cited as examples. SUB MAXILLARY ADENITIS. MAXILLITIS. Mostly in solipeds and unilateral. Causes; traumatic; calculus; infections; ablation of papillæ. Symptoms; tardy mastication; salivation; buccal heat and fœtor; submaxillary swelling and tenderness; morsels retained under tongue; papilla and duct swollen, tender and firm; abscess. Treatment; remove causes; dislodge foreign bodies; antiseptic lotions and packing. This is rarely seen in other animals than solipeds, is mostly unilateral, and due to the introduction of microbes along with vegetable spikes (barley awns, brome, wheat or oat spikes or glumes) or other foreign bodies. It may also be caused by calculi obstructing the duct. The orifice of each duct, to one side of the frænum lingui, is imperfectly closed by a triangular valvular projection, which in some countries is erroneously cut off as a diseased product (barbs), thus opening the way for the introduction of foreign objects. The microbes are usually pus germs and tend to abscess of the gland. As in the case of the Stenonian duct the presence of these germs tends to the precipitation of the salivary salts and the formation of calculi.
