Young children whilst cutting their first set of teeth often suffer severe constitutional disturbance. At first there is restlessness and peevishness, with slight fever, but not unfrequently these are followed by convulsive fits, as they are commonly called, which depend on the brain becoming irritated: and sometimes under this condition the child is either cut off suddenly, or the foundation of serious mischief to the brain is laid. The remedy, or rather the safeguard, against these frightful consequences is trifling; safe, and almost certain, and consists merely in lancing the gum covering the tooth which is making its way through. When teething is about it may be known by the spittle constantly drivelling from the mouth and wetting the frock The child has its fingers often in it* mouth, and bites hard any substance it can get hold of. If the gums be carefully looked at, the part where the tooth is pressing up is swollen am redder than usual; and if the finger be pressed on it the child shrinbs and cries showing that the gum is tender. When, these symptoms occur, the gum should be lanced, and sometimes the tooth comes through the next day, if near the surface; but if not so far advanced the cut heals and a scar forms, which is thought by some objectionable, as rendering the passage of the tooth more difficult. This, however, is untrue, for the scar will give way much more easily than the uncut gum. If the tooth do not come through after two or three days, the lancing may bo repeated; and this is more especially needed if the child be very fractious, and seem in much pain. Lancing the gums is further advantageous, because it empties the inflamed part of its blood, and so reliever the pain and inflammation. The relief children ex perience in the course of two or three hours from the operation is often very remarkable, as they almost immediately become lively and cheerful.
