_Treatment._—In the first place the patient should be kept in a cool room, the temperature of which must be regulated to suit the child’s feelings of comfort, and the diet adapted to the strictest principles of abstinence. When the inflammatory symptoms are severe, bleeding in some form is often necessary, though, when adopted, it must be in the first stage of the disease; and if the lungs are the apprehended seat of the inflammation, two or more leeches, according to the age and strength of the patient, must be applied to the upper part of the chest, followed by a small blister; or the blister may be substituted for the leeches, the attendant bearing in mind that the benefit effected by the blister can always be considerably augmented by plunging the feet into very hot water, about a couple of hours after applying the blister, and keeping them in the water for about two minutes. The first internal remedies should commence with a series of aperient powders, and a saline mixture, as prescribed in the following formularies; at the same time as a beverage to quench the thirst, let a quantity of barley water be made, slightly acidulated by the juice of an orange, and partly sweetened by some sugar-candy, and of which, when properly made and cold, let the patient drink as often as thirst or the dryness of the mouth renders necessary. _Aperient Powders._—Take of scammony and jalap, each twenty-four grains; gray powder and antimonial powder, of each eighteen grains. Mix and divide into twelve powders, if for a child between two and four years of age; into eight powders, if for a child between four and eight years; and into six powders for between eight and twelve years of age. One powder to be given, in a little jelly or sugar and water, every three or four hours, according to the severity of the symptoms.
