There are several varieties of fractures. What is called a simple fracture, is a mere fracture of the bone, unattended by contusions. In a compound fracture there is an external wound or a protruded bone. The presence of fracture can very readily be detected by the peculiar crepitous or grating sound heard on moving the parts-There is also more or less pain and swelling present. In setting the hones the fractured parts are placed together, so that, when united, the limb shall be as nearly as possible as it was, before the bone was broken. While the union or knitting together of the bone is going on, the limb should be kept perfectly still. This is done by means of long splints and bandages, the bandages not applied very tightly, or they may prevent the free circulation of the blood. Both before and after the limb is set, if much swelling and heat are present, cold water or Arnica should be applied, the cloths which cover the part being kept constantly wet. Where there is much laceration of the parts, Calendula should be applied.

It would be impossible and in fact unnecessary, to go into the minutia of the treatment of fractures here, as every one will see the importance of calling in the aid of the experienced surgeon.
