_Saline Mixture._—Take of mint water, six ounces; powdered nitre, twenty grains; antimonial wine, three drachms; spirits of nitre, two drachms; syrup of saffron, two drachms. Mix. To children under three years, give a tea-spoonful every two hours; from that age to six a dessert-spoonful at the same intervals; and to children between six and twelve, a table-spoonful every three or four hours. The object of these aperient powders is to keep up a steady but gentle action on the bowels; but whenever it seems necessary to administer a stronger dose, and effect a brisk action on the digestive organs—a course particularly imperative towards the close of the disease—two of these powders given at once, according to the age, will be found to produce that effect. Thus, two of the _twelve_ for a child under four years; and two of the eight, and two of the six, according to the age of the patient. When the difficulty of breathing becomes oppressive, as it generally does towards night, a hot bran poultice laid on the chest will be always found beneficial. The diet throughout must be light, and consist of farinaceous food, such as rice and sago puddings, with beef tea and toast; and not till convalescence sets in, should hard or animal food be given. When measles assumes the malignant form, the advice just given must be broken through; food of a nutritious and stimulating character should be at once substituted and administered in conjunction with wine, and even spirits, and the disease regarded and treated as a case of typhus. But as this form of measles is not frequent, and, if occurring, hardly likely to be treated without assistance, it is unnecessary to enter on the minutiæ of its practice here. What we have prescribed in almost all cases will be found sufficient to meet every emergency without resorting to a multiplicity of agents. The great point to remember in measles is not to give up the treatment with the apparent subsidence of the disease, as the after-consequences of measles are too often more serious and more to be dreaded than the measles themselves. To guard against this danger, and thoroughly purify the system after the subsidence of all the symptoms of the disease, a corrective course of medicine, and a regimen of exercise should be adopted for some weeks, according to the cure of the disease.
