I have but little to say here about the general signs of brain disease in infancy and childhood, because they will need minute notice afterwards. All that I would at present observe is, that you must not at once conclude that a child's head is seriously affected, because it is heavy and fretful and passionate, and refuses to be amused. The head, as we know by our own experience, suffers by sympathy in the course of almost every ailment, certainly of every acute ailment, at all ages. If the babe is not sick; if its bowels can be acted on by ordinary means; if, though drowsy, it can be roused without difficulty; if, though it may prefer a darkened room, it does not shrink from the light when admitted gradually; if it has no slight twitchings of its fingers or of its wrists; if the head, though hot, is not hotter than the rest of the body; if the large vessels of the neck, or the open part of the head, or fontanelle as it is termed, in an infant in whom the head is not yet closed, are not beating violently; and, above all, _if when it cries it sheds tears_, you may quiet your mind on the score of the child's brain, at any rate until the doctor's visit, and may turn a deaf ear to the nurse or the friend who assures you that the child is about to have convulsions or to be attacked by inflammation of the brain.

No mother should be without it. CHAPTER III. THE GENERAL MANAGEMENT OF DISEASE IN INFANCY AND CHILDHOOD.
