1st. Persistent vomiting in a child means acute gastritis. Stop all food for twenty-four hours. 2nd. Encourage the child to drink large quantities of slightly warm water; this will wash the stomach out and frequently stops the vomiting. 3rd. When the child is quiet wash out the bowels. 4th. If vomiting persists, use iced champagne as directed. ACUTE INTESTINAL DISEASES OF CHILDREN The large infant mortality that results from intestinal diseases during the summer months is deserving of the most careful consideration, both of the physician and the parent. Apart from the excessive heat of the summer, there is no doubt that an unfavorable environment, which means bad hygienic surroundings, bad sanitary conditions, bad food and home influences, contributes largely to the enormous number of these serious cases. Education, while it may be expected to influence favorably the sanitary and other conditions in the home, cannot change the home location. The child must continue to live in the same environment. It is in this class of cases that these summer diseases are so very fatal. Children in better circumstances can take advantage of conditions which are denied to the tenement child. The diseases must therefore be faced and treated under these existing conditions. In addition to the climate and the environment, there are certain factors that occur in all classes which result in intestinal derangement. If the stomach or bowels are not performing their function properly, or if the food or method of feeding is wrong, these, plus very hot, humid weather, invariably result in serious intestinal disease. The mother must be taught to interpret properly the meaning of a green, loose stool in the summertime; she must appreciate that it is the danger signal and must be regarded seriously. The very best preventive against summer diseases of the intestine is to guard particularly against any trouble with the child's stomach at all seasons of the year. A healthy stomach and bowel will resist disease, even in very hot weather.
