In the case of an elder child, all meat and vegetables should be at once forbidden, and the only food allowed for a day or two must be rice and milk, arrowroot, or milk and water. The dose of castor oil which is so frequently given by nurses in these cases under the impression that the oil is 'healing,' is only of service when the diarrhœa has been caused by food of improper quality or quantity. It then aids nature in her efforts to get rid of the offending matter, which by its irritation is doing the mischief. In such instances one dose of the oil is quite sufficient. It has no 'healing' virtues, and should not be repeated from day to day. Children who are teething are frequently affected with looseness. A warm bath every evening, and attention to the gums, will be ordinarily all that is required in these cases, at least during the cold months. It is of the utmost importance, however, during the summer that such patients, if living in the city, should be at once removed into the country; otherwise their lives are in danger. Looseness of the bowels in children is usually best treated by careful management of the clothing and diet, by attention to all that affects the health, and by avoiding as much as possible the administration of medicines. No case should be allowed, however, to run on without seeking competent medical advice. An excellent remedy for the diarrhœa of children is the subnitrate of bismuth. This medicine may be disguised in the food, as in a case narrated by Dr. Inmann. A lad about ten years old was brought to him by an aunt, who stated that the boy suffered much from diarrhœa, and was emaciating visibly; that he would not try any domestic remedy, was an obstinate fellow, and determined to take no medicine. After sending the lad to another room the doctor recommended the lady to get some white bismuth and give it to the cook, telling her to mix a large pinch of it with some butter, and to send in the bread and butter so arranged that the lady would know which was for the boy. This was done. The lad was duly drugged without his knowledge, and the diarrhœa stopped in two days. INDIGESTION. Infants and young children suffer often from indigestion, or _dyspepsia_, as well as adults. One of the most frequent signs of this disorder is vomiting. But every infant which throws up its milk is not suffering from indigestion. Vomiting is sometimes a sign of health, and shows that the stomach is vigorous enough to free itself promptly from excess of food. The child is thus saved from the effects of over-feeding. The obvious remedy is to diminish the quantity of milk taken at each nursing or meal.
