It is extremely rare in infancy, though I saw it once in a babe eight months old, and is comparatively seldom met with before the age of five years. From five to ten years old it is more frequent than from ten to fifteen, but it is consolatory to know that it is less fatal in early childhood than at any subsequent time of life, and that cases of such exceedingly mild character that the child's condition can be more properly described as ailing rather than ill, are then far from uncommon. The symptoms, however, are in all instances similar in kind, though widely varying in degree, and the duration of the fever is, as nearly as may be, three weeks. By this it is not meant that at three weeks' end the child who has had typhoid fever is well again, but only that the temperature, which had hitherto been high, and always higher at night than in the morning, has subsided, that the skin has become less dry, the tongue slightly moist, the intelligence more clear, that the fever has run its course. For the first week or ten days, the symptoms have probably become every day more grave; and for the next ten the doctor could find no better consolation than the assurance--happy if he could give it--that the condition was not worse, but that you must have patience, for the time for improvement had not yet arrived. If the attack has been severe, the child will be left greatly exhausted, sadly emaciated, and suffering from the effects of that ulceration of the bowels which accompanies the fever, and from which life may still be in imminent danger. But the fire is quenched; the question is no longer how to put out the conflagration, but how to repair the mischief it has caused.
