“The first thing, of course, to be done is to send immediately for a medical man. Have a plentiful supply of cold and hot water always at hand, ready for use at a moment’s notice. The instant the paroxysm is on the child, plentifully and perseveringly dash cold water upon his head and face. Put his feet and legs in hot salt-mustard-and-water, and if necessary place the child up to his neck in a hot bath, still dashing water upon his face and head. If he does not quickly come round, sharply smack the back and buttocks. As soon as a medical man arrives, he will lose no time in thoroughly lancing the gums, and in applying appropriate remedies. During the intervals, great care and attention must be paid to the diet. If the child be breathing a smoky, close atmosphere, he should be immediately removed to a pure one. Indeed in this disease there is no remedy equal to a change of air—to a dry bracing neighbourhood. Even if it be winter, change of air is the best remedy, either to the coast or to a healthy farmhouse. In a case of this kind where it is not practicable to send a child from home, then let him be sent out of doors during the greater part of every day; let him, in point of fact, almost live in the open air. I am quite sure from an extensive experience that, in this disease, fresh air, and plenty of it, is the best and principal remedy.”
