_Symptoms._ The concentrated acid causes salivation, dysphagia, anorexia, thirst, emesis in vomiting animals, colics, arched back, retracted abdomen, odor of the acid in the breath, dark or greenish brown albuminous urine, trembling, lowered temperature, debility, stertorous breathing, clonic or tonic spasms, paralysis of the hind limbs, stupor, coma and death. _Lesions._ In the mouth, throat, stomach and intestines are whitish, cauterized patches, with active inflammation beneath and around them, and ecchymosis. The blood is fluid and dark colored, extravasations or effusions on the brain or in the lateral ventricles, with pulmonary congestion and parenchymatous nephritis. _Treatment._ If available, give vinegar proportionate to the amount of carbolic acid taken. Alcohol is a good substitute. Emesis should be encouraged when available. Next mucilaginous agents and bland oils to dilute the acid are required. Glauber salts may assist in neutralizing and expelling the acid. POISONING BY CREOSOTE. Irritates, coagulates albumen, and blood, arrests heart, colic, emesis, salivation, labored breathing, vertigo. Lesions: Congestion, corrosion, dark clotted blood, odor. Treatment: Mucilaginous agents, emesis, oily laxatives. On the mucous membrane creosote has a very irritant action, coagulating the albumen, causing violent inflammation. It also coagulates the blood and when injected into the veins, stops the action of the heart. Taken by the mouth it causes violent colics, emesis in vomiting animals, salivation, laborious breathing, convulsions, vertigo and death. At the necropsy the stomach is found congested of a dull red color, and corroded, and the vessels contain dark clotted blood. A dog died from a dose of 2 drachms. The odor of creosote is marked. _Treatment._ Emesis, white of eggs, mucilaginous liquids, and oily laxatives. POISONING BY SEEDS OF RICINUS COMMUNIS. Superpurgation. Poison in seeds. Diluents, demulcents, stomach pump, laxatives if necessary. An overdose of castor oil may kill by gastro-intestinal congestion and superpurgation. Apart from the oil however the seeds contain a very active poison, which has been fatally ingested by horses with grain or otherwise. Five and a half ounces of the seeds have proved fatal. (Pelletier. Wende). The _symptoms_ are those of acute colic and gastro-enteritis. The indications are to wash out the stomach by abundant demulcents and the stomach pump, and if necessary to hasten the expulsion of the offensive matters by bland laxatives (olive oil, Glauber salts). POISONING BY CROTON SEEDS AND OIL. Fatal dose without water. Vomiting animals. Superpurgation. Lesions. Treatment: diluents, demulcents, stomach pump. Opiates.
