period the tape may be removed, and the wounds allowed to heal. During the course of treatment it is always advisable to change the tape several times by cutting the knot off one end of the old one, stitching the new one to it and drawing it through. _Puncture of the pouch at its lower part_ is a very simple operation when the accumulation of pus is abundant and chronic. The distended pouch gravitates downward largely separating the parotid from the deeper vessels and nerves, and finally fluctuates toward the lower end of the gland. In extreme cases it even opens and discharges. When fluctuation can be felt the sac may be incised with a bistoury or abscess knife and treated like a common sore. Opening with a pointed or olive-shaped cautery has the advantage of checking hæmorrhage and securing more perfect drainage. When there is no fluctuation the incision must be made just beneath the lower border of the parotid, the parotidoauricularis being first cut through, then the gland dissected from the deeper parts when the distended sac can usually be felt and opened. If not felt at once it can easily be reached by a careful dissection upward through the loose subparotidean connective tissue, with the finger nail or handle of the scalpel. A free opening may be made and the wound injected daily with a weak antiseptic solution. ABSCESS OF THE FALSE NOSTRIL. In young horses as the result of injury from the bridle or severe _coryza_, a circumscribed swelling sometimes appears on the outer flap of the nostril, at first firm, hot and tender, with a surrounding pasty infiltration, then forming into a tense elastic ovoid mass, the size of a pigeon’s or chicken’s egg. It may become chronic and remain for an indefinite period comparatively insensible to touch and only slightly interfering with the movements of the nostrils. As soon as the elastic tension betrays the presence of pus it should be evacuated by a free incision made from inside the nostrils and the wound plugged with medicated tow and allowed to heal by granulation. NEOPLASMS IN THE HORSE’S NOSE. Nasal fibrous polypus, connection, form, size, bony distortion, obstructed breathing, abrasion, ulceration, sloughing, submucous polypus, structure, degeneration. Symptoms, sneezing, snuffling, discharge, palpation, bony swelling, tenderness. Treatment, forceps, hook, ecraseur, knife, saw. Actinomycosis. Sarcoma, Carcinoma. Consistency, structure, fœtor, glandular swelling. Treatment. Recurrence. Fatty tumors. Bony tumors: cancellated or compact tissue, localized or extended. Cysts. Strongyli. Angioma. Varicosity. Color, obstruction to breathing, hæmorrhage, cicatrization. These are essentially surgical diseases yet as they induce Chronic Catarrh they may be profitably noticed here.
