When eczema sets in acutely, with general feverish disturbance, cooling medicines are required, and the help of the doctor becomes necessary. These are the cases in which the eruption is not confined to the head or the face, but extends over the body generally. The child must be dressed as loosely as possible; and when in its cot, should lie there with no other covering than its little shirt; and nothing gives so much relief to the irritation as the abundant use of powder, either simple starch powder, or ten parts of starch powder to one of oxide of zinc, or carbonate of bismuth. All powders must be absolutely free from grit, or, in other words, quite impalpable; otherwise they irritate the surface. On the face and other parts where it can be employed, the puff may be used to apply the powder; but between the creases of the skin--which it is important to keep apart--fine linen, lint, or charpie must be employed, covered freely with powder, so as to prevent the surfaces from coming into contact. If the irritation is very distressing, a weak spirit lotion with a little carbolic acid may sometimes be sponged over the surface, and the powder renewed immediately; or other forms of soothing lotions may be used to abate the irritation. When the scalp is affected in the acute form of eczema crusts form very quickly; or in other cases they collect because people fear to disturb them when they see the raw surface beneath. It is, however, a grievous mistake to allow them to collect; they are in themselves a source of irritation, and they entirely prevent any application reaching the skin beneath. They must always be removed, and never be allowed to form again. They can be removed either by the employment of a poultice, half of bread, half of linseed meal, or by the application over-night of a handkerchief soaked in sweet oil, and covered over with a piece of oiled silk, which softens the crusts effectually, and allows of their easy removal by abundant washing with weak soap and water. The best applications afterwards vary so much that it is impossible to lay down any positive rule. Sometimes the Carron oil, as it is termed: a liniment compound of equal parts of linseed oil and lime-water--a popular and most useful application in burns--gives most ease to the irritated skin; sometimes the mere exclusion of the air by means of the india-rubber cap; sometimes the abundant use of powder. In every case, at least once in every twenty-four hours the whole surface must be washed quite clean with barley water or thin gruel; and when the discharge lessens or ceases, as it will do in the course of time, then, but not till then, various ointments may be of service.
