Now, with regard to food.--If the child be at the breast, keep him entirely to it. If he be weaned, and under two years old, give him milk and water, and cold water to drink. If he be older, give him toast and water, and plain water from the pump, as much as he chooses; let it be quite cold--the colder the better. Weak black tea, or thin gruel, may be given, but not caring, unless he be an infant at the breast, if he take nothing but _cold_ water. If the child be two years old and upwards, roasted apples with sugar, and grapes, will be very refreshing, and will tend to cleanse both the mouth and the throat Avoid broths and stimulants. When the appetite returns, you may consider the patient to be safe. The diet ought now to be gradually improved. Bread and butter, milk and water, and arrowroot made with equal parts of new milk and water, should for the first two or three days be given. Then a light batter or rice pudding may be added, and in a few days, either a little chicken or a mutton chop. The essential remedies, then, in scarlet fever, are, for the first few days--(1) plenty of fresh air and ventilation, (2) plenty of cold water to drink, (3) barm poultices to the throat, and (4) the Acidulated Infusion of Roses Mixture as a medicine. Now, then, comes very important advice. After the first few days, probably five or six, sometimes as early as the fourth day--_watch carefully and warily, and note the time, the skin will suddenly become cool_, the child will say that he feels chilly; then is the time you must now change your tactics--_instantly close the windows and put extra clothing_, a blanket or two, on his bed. A flannel nightgown should, until the dead skin have peeled off, be now worn next to the skin, when the flannel nightgown should be discontinued. The patient ought ever after to wear, in the day time, a flannel waistcoat. [Footnote: On the importance--the vital importance--of the wearing of flannel next to the skin, see "Flannel Waistcoats."] His drinks must now be given with the chill off; he ought to have a warm cup of tea, and gradually his diet should, as I have previously advised, be improved.
