In =cattle= have been observed variable and capricious appetite, imperfect rumination, tympany, eructations, vomiting, rumbling of the bowels, constipation, slow painful walk, progressive emaciation and debility. When blood is discharged by emesis or defecation the suspicion of gastric tumor may be strengthened. In the =dog= there are the usual signs of chronic gastritis, thirst, anorexia, stiffness, a disposition to lie, sunken eye, dyspnœa, vomiting, often of blood. The discharge of blood by mouth and anus, the distended abdomen, the tumor usually easily detected by manipulation, and the progressive loss of condition are strongly suggestive. _Treatment_ of these cases is hopeless. In the dog alone for a circumscribed tumor, laparotomy, the removal of the tumor and closure of the wound may be tried. ACUTE INTESTINAL INDIGESTION IN THE HORSE. INTESTINAL TYMPANY. Definition. Causes: Debility—general and local, and its causes, fermentescible food, legumes, new grain, paralyzing seeds, musty fodder, defective teeth, jaws and salivary glands, iced water after grain, verminous embolism, chill. Symptoms: Anamnesis, colic, gaseous distension, stupor, death, diagnosis from spasmodic colic. Course: Fatal in two hours, or more. Recovery. Lesions: Distension of bowels with carburetted hydrogen, carbon dioxide, and nitrogen, redness of intestinal mucosa, anæmia of abdominal organs, congestion of cutaneous and surface vessels. Treatment: Stimulants, antiseptics, enemata, chloral hydrate, puncture, eserine, pilocarpin, friction, massage, exercise, dieting, bitters. _Definition._ A gaseous overdistension of the intestines, from fermentations in the ingesta, but also in part from air that has been swallowed, and from carbon dioxide exhaled from the blood circulating in the intestinal mucosa. _Causes._ These are to a large extent the same as those of gastric tympany. General and digestive debility resulting from former disease, from spare diet, from unsuitable or indigestible food, from anæmia, from parasites, from hemorrhages, is a potent predisposing cause. Weakness of the alimentary canal from catarrh, or other persistent disease, from impaired innervation, from embolism of the vessels and imperfect circulation also predisposes, or again the lack of vermicular movement and of the mingling of the digestive fluids with the food, leaving the latter in a specially fermentescible condition. As direct _exciting causes_ may be named: Very _fermentescible food in excess_, such as the leguminous products (beans, peas, vetches, cowpea, alfalfa, sainfoin, clover) in their green condition. These contain an excess of protein compounds, which should be mainly digested in the stomach, and if passed rapidly in large quantity into the intestines, they fail to be sufficiently acted on by the trypsin, and are specially liable to fermentation. Very rapidly grown and aqueous grasses are similarly liable to decomposition.
