_Symptoms._ These usually manifest themselves from two to four days after the operation of the cause. There is much difficulty in deglutition, the effort to swallow either solids or liquids causing acute suffering, with extension of the head on the neck and strained contraction of the facial muscles. If the liquid succeeds in passing the pharynx, it is arrested at the seat of inflammation and regurgitated through the nose and mouth, or in solipeds through the nose only. This takes the appearance of emesis even if nothing actually comes from the stomach. The animal shakes the head violently, breathes hurriedly, and has fits of paroxysmal coughing. A wave extending from below upward along the jugular furrow and followed by nasal discharge is a marked symptom, as the violence of the inflammation increases. Uneasy movements of the limbs, pawing and lying down and rising, indicate the existence of colic, and this is aggravated by the administration of anodynes or antispasmodics by the mouth. In cattle, rumination is arrested, froth accumulates around the lips, the rumen becomes tympanitic, and colicy movements appear. Oftentimes a swelling extends upward in the jugular furrow, and even in its absence, pressure with the fingers along the furrow will often detect an area of tenderness with or without local swelling. Fever with more or less elevation of temperature, is a general symptom. There may be wheezing breathing or loud stertor. The passage of a probang is arrested by the swelling or spasm at the diseased part and when withdrawn may be covered with pus or fœtid _debris_. In the horse a small probang may be passed through the nose. _Treatment._ In a slight congestion at the seat of a recent obstruction and which tends to renewed obstruction, little more is necessary than to restrict the feed for a few days to soft mashes so that irritation of the sensitive surface, spasm and the arrest of the morsel may be obviated. Plenty of pure water or of well boiled linseed or other gruel should be allowed. In cases in which the obstruction is still present in the gullet, its removal by probang or looped wire is the first consideration, to be followed by the measures mentioned above.
