Dogs are rarely the subjects of simple coryza, though it is constant in distemper. It sometimes proves troublesome in puppies and old dogs. A laxative (½–1 ounce castor oil) may be followed in strong and very feverish cases by tartar emetic (¼—½ grain) three times a day. Spraying or sponging the nose with a weak solution of chlorate of potass, common salt, or potassium permanganate will greatly relieve. Inhalation from burning sulphur, or from carbonate of ammonia, or both may be used when sponging or spraying is difficult. In inveterate cases, the weak electric current sent through the cheeks, or the insufflation of acetanilid, iodoform or calomel may be tried. As a rule, saltpeter in five grain doses, given in the water, will prove helpful, and in weak conditions wine, tincture of gentian or nux vomica may be used. CHRONIC NASAL, CATARRH. NASAL GLEET. OZŒNA IN THE HORSE. Chronic catarrh in horse, simple form, loss of tone, inflammation, nature of discharge, glandular swellings, differentiation from glanders. Treatment, astringent, tonic, stimulant, hygienic, locally astringents, antiseptics, injections. A chronic discharge from the nose is often seen in the horse as a sequel of _coryza_ or _sore throat_, or as an attendant on other affections of the upper air passages, and the different conditions productive of this symptom may here be noticed. 1ST. SIMPLE NASAL CATARRH. NASAL GLEET. OZŒNA. In long standing _coryza_ the nasal mucous membrane becomes relaxed, fails to acquire its lost tone and continues to pour out a muco-purulent product. This is really a persistence of inflammation of a low type, under the influence of which the membrane secretes pus in place of its normal mucus. The discharge is white, thick, creamy, has little tenacity, and flows uninterruptedly. There may be slight enlargement of the submaxillary glands, and if the case is of long standing and the patient in low condition sores may appear on the mucous membrane. These ulcers are distinguished from those of _glanders_ by the absence of the unhealthy angry aspect and excavated borders of the latter, by the absence of the small nodular deposits on the mucosa, by the less viscid nature of the secretion, and by the absence of submaxillary swellings, or if these exist, by their being less nodular, less indurated and less firmly attached to surrounding parts. The coincidence of ulcers and submaxillary swellings is always, however, matter for the gravest suspicion, and such cases should, as a rule, be subjected to the mallein test. (See Glanders and Farcy). _Treatment._ In simple nasal catarrh, due alone to the relaxation of the mucous membrane, the internal use of tonics and the local application of astringent solutions to the nose rapidly restore the parts to a healthy state.
