AEEEST OF HEMOERHAGE 7 



Cliaracteristics — It is a contused, lacerated "wouiid ; titers 

 is a wound of entrance and possibly a ■wound of exit. The 

 wound of entrance is smaller than the ball, because the skin 

 is stretched as the ball hits it ; should it be larger than the 

 ball, a foreign body has been carried in with it. With the 

 shot fired close to the animal, the hair is singed by the 

 powder ; when the ball grazes the surface a friction burn 

 results. The wound of entrance has either smooth, frizzled 

 or lacerated and depressed edges. Hemorrhage is wanting 

 unless a larger vessel has been cut. The wound of exit is 

 larger than the ball, irregular and everted. 



Prognosis — Unless septic material has been carried in by 

 the missile, the probe or the surgeon's finger, or vital parts 

 destroyed or injured so as to interfere with the future use- 

 fulness of the animal, the prognosis is good.
