Of these ammonia, in the form of strong liquid, given in mistake for aromatic spirit or solution of acetate, is the only likely form of poisoning to occur in horses. This mistake has frequently happened in the careless dispensing of ammonia compounds.

Symptoms

Blistered lips and mouth, patches of epithelium sloughing off in ragged shreds. Ropy and offensive mucus dribbling from the mouth and from the lips, and hanging in ropes more or less straw-coloured or tinged with blood, swelling of the tongue, sore throat, difficulty of deglutition, coughing, and dyspnoea. Intestinal disturbance with loose eructations and apparent soreness throughout the canal. Pained expression and listlessness.

Treatment

Copious draughts of dilute vegetable acids, as lime-juice, citric or tartaric acid, vinegar and water. These should be given at frequent intervals to neutralize the caustic ammonia, and form harmless combinations. Inhalation of steam to relieve the irritated air-passages and soothe the inflamed mouth; where suffocation threatens, tracheotomy will require to be performed. Linseed-tea, barley-water, thin gruel, bran mashes, and soft food only for several days should be allowed, as any dry, hard substance is calculated to injure the abraded surfaces of the mouth. Where the patient refuses all sloppy food, he may be cautiously drenched with eggs beaten up in milk. If constipation follows, aperients must not be given, but reliance placed on the nature of the diet, and at most, a glycerine enema administered from time to time.
