When the foreign body may be seen the child should be made to blow the nose, first closing the well side with the finger. If this does not expel the object the child should be made to sneeze by tickling the free nostril with a feather or by taking snuff. The mother should never permit the use of instruments by one unskilled in an effort to rid the nose of an obstruction. There is great danger of seriously injuring the delicate structure of the nose in this way or of pushing the object so far in that it may necessitate an operation to extract it. It is much safer to seek medical aid before any damage is effected. It seldom does harm to wait until the right assistance is at hand; it often does serious harm to be too smart in these little matters. Foreign Bodies in the Throat.--If the foreign body is in the upper part of the throat and can be seen it may be removed with any instrument that can grasp it. The child may be immediately held up by its feet when the article may be shaken out. If it is further back or in the air passages the child should be made to vomit by tickling the throat with a feather or with the finger held in the throat till it does vomit. When the object interferes with breathing a physician should be sent for in a hurry. In the meantime the family may try to dislodge it by having the child bend forward or by holding it with the head downward and, while in this position, sharply striking the back with each cough. Striking the chest when in this position may effect the same purpose. If no success follows this procedure try the reverse position. Have the child bend backward over the arm of a sofa, for example, or put him in bed with the body hanging out of the bed face upward. If none of these effect relief you must depend upon the skill of the physician. A Bruise or Contusion.--A bruise or contusion is an injury to the tissues underneath the skin, but this does not imply that the skin itself is opened or damaged. In every bruise the small blood vessels are ruptured, and the blood collects in the tissues causing distention, swelling and pain. The blood is held in the tissues, it is stagnant, becomes dark in color and so produces the bluish discoloration that we see in all bruises. The color varies according to the extent of the collected blood. At first it is red and inflamed looking, then purple, then black, then greenish and finally citron. The so-called "black-eye" is a typical example of this degree of bruise. After a bruise the parts swell from the collection of blood and from the accompanying inflammation. This causes pain which persists for a day although the spot may be sore and tender for a week or more.
