 pension, and in some of his irregiilarities in living the wound of the hip,

 and thus, several months after being wounded, he was cut ofl". The ball 

 is attached, and seen to be a iiattened piece of lead. The bone exhibits 

 the consequences of inflammation, absorption, and granulation, since the 

 hole made by the ball is enlarged by absorption, and the surface is rough 

 with granulations of bone. 



In the neighbourhood of the bullet there has been a 

 perforation of the bone, and the walls of this perforation are 

 necrotic and carious. Eound about the perforation on both
