This is a disease of the mucous membrane of the mouth, stomach, and bowels; and when severe, may be traced throughout the whole alimentary canal. Though thrush may attack persons at any stage of life, still it is regarded as a disease more peculiarly incident to childhood and infancy; and is generally induced by an abrupt change of diet, or some cause impairing the nutritive quality of the mother’s milk, which produces this eruptive fever in the infant’s digestive organs. The _symptoms_ of thrush are heat, pain, and restlessness, followed by a series of small, raised, white spots, scattered over the mouth, tongue, and lips; sometimes there are but few, at others the whole mouth is studded with them. After a day or two, they enlarge and become distended with a white puriform fluid; the eruption looking like a cross of minute beads: this completes the suppurating or second stage; after which, the vesicles proceed to ulceration, when they burst, discharge their fluid, and degenerate into small flat ulcers, causing throughout, but especially in this the last stage, considerable irritation and pain. _Treatment._—Having, if possible found the immediate cause of the disease, and if an improper food, removed it, the child must be carefully fed on a diet that in no way can irritate the tender and inflamed lining membrane; and, if necessary, a few spoonfuls of beef tea are to be given occasionally as a gentle stimulant. The medical treatment consists in the exhibition of the subjoined powders and mixture, and the employment, each evening, of the warm bath as a sedative to the restless child. Take of Grey Powder 8 grains. Scammony 6 grains. Rhubarb 3 grains. Mix and divide into nine powders for an infant from six to twelve months, giving one powder twice a day; into six powders for an infant from one to two years old, one twice a day; and into four powders for a child of three years, to be given in the same manner. Take of Mucilage ½ ounce. Castor Oil 2 drachms. Syrup 2 drachms. Mix well in a mortar, and add Dill Water ½ ounce. Mix, and give a small tea-spoonful twice a day to an infant from six to twelve months; three times a day to one of from one to two years; and every six hours to a child of three years old. Should the thrush have proceeded to ulceration, the mouth of the infant or child should be washed out by a lotion, made by dissolving a small quantity of alum or borax in water well sweetened with honey; and then, by tying a fold of lint to a piece of stick, and using it as a mop, to cleanse the mouth, having first well wetted it in the lotion.
