External haemorrhage is not necessarily any criterion of the danger to life. There may be very little external haemorrhage and yet pro- fuse haemorrhage may take place internally owing to some vital organ having been penetrated. In the case of a punctured wounct perforating a part of the body there are two wounds, one} a wound of entry arid the other, a wound of ejsit.
