But, fortunately, our knowledge of these little diseases, like Mercutio's wound, is "not so deep as a well, nor so wide as a church door; but 't is enough" for all practical purposes. The general plan of treatment in all of them might be roughly summed up as, rest in bed in a well-ventilated room; sponge-baths and packs for the fever; milk, eggs, bread, and fruit diet, with plenty of cool water to drink, either plain, or disguised as lemonade or "fizzy" mixtures; mild local antiseptic washes for nose and throat, and mild internal antiseptics, with laxatives, for the bowels and kidneys. There is no known drug which is specific in any one of them, though their course may be made milder and the patient more comfortable by the intelligent use of a variety of remedies, which assist nature in her fight against the toxin. Not knowing the precise cause, we have as yet no reliable antitoxin for any. Now very briefly as to the earmarks of each particular member of this children's group. It may be said in advance that the "openings" of all of them (as chess-players call the first moves) are very much alike. All of them are apt to begin with a little redness and itching of the mucous membranes of the nose, the throat, and the eyes, with consequent snuffling and blinking and complaints of sore throat. These are followed, or in severe, swift cases may be preceded, by flushed cheeks, complaints of headache or heaviness in the head, fever, sometimes rising very quickly to from one hundred and four to one hundred and five degrees, backache, pains in the limbs, and, in very severe cases, vomiting. In fact, the symptoms are almost identical with those of an attack of that commonest of all acute infections, a bad cold, and probably for the same reason, namely, that the germs, whatever they may be, attack and enter the system by way of the nose and throat.
