If there is scarlet fever or scarlatina (the milder sort) about, and your little girl begins to ail from no apparent cause, suffering from loss of appetite and cheerfulness, if she has chills alternating with flushing, hot skin and uneasy sleep, with a little headache and maybe sore throat, with a high temperature and furred tongue, having little red papillæ showing through—the “strawberry tongue”—then in all probability she has an attack of scarlatina. We shall hope it is to be a simple one. Cure it you can’t; but the little patient may be guided through it. The doctor is the man to trust. But there is one thing you can assist him in most materially, and that is in seeing that the patient is completely isolated from the rest of the house, for the simplest cases in one child may generate the worst in others. It is a more dangerous disorder than measles, and mind that, until the doctor gives a clean bill of health, and the skin has entirely peeled, no other child should be allowed into the room. Indeed, the success in any one case depends on careful nursing, and isolation will prevent it spreading. Disinfectants must of course be used—but the doctor will tell you all this—and food taken from the room must not even be given to the cat or dog. She will pull through if scientifically treated, and soon grow out of any little weaknesses that may remain. _St. Vitus’s Dance._—Will she grow out of this? I do really think that the medical profession has a good deal to learn even yet concerning this strange ailment. But its symptoms are unmistakable. The uncontrollable, fidgety movements may be slight or very great; they may be on one side of the body or both. She will grow out of it, however, if the treatment is most skilful. The health must be properly attended to, and all rules obeyed which the doctor shall lay down. The digestion and the teeth must be seen to, with abundance of fresh air and non-exciting exercise and recreation. The bath often does wonders—tepid, of course—given in a warm room. There are certain kinds of methodical drill which, moreover, do good, and many kinds of tonics. But cod-liver oil or marrol is perhaps one of the best, as it is a food. The doctor will for each case prescribe the necessary tonic. Dear me! what thousands of thousands of lives might be saved if we could only act up to the physician’s instructions. I must bid the young mother beware of quack medicines, and of all such dangerous drugs as chloral, bromides, and phenaticin, etc. In the hands of the physician these are useful; in those of the uninitiated they are verily like razors grasped by infant fingers.
