100 Injuries of Bone. 



3. 156. Gunshot Fracture of the Shaft of the Humerus. — 



Lower half of a left humerus — macerated, showing the effects 

 of septic osteo-myelitis following the above. 



The patient was a soldier who was wounded at Waterloo. 



The bone at the seat of fracture has necrosed, and has 

 been in process of separation. Lower down the opening up 

 of the vascular channels shows that there has been inflammation 

 of the periosteum, although not with the formation of any new 

 bone. F. P. C. 205. 



Presented by Professor John Thomsoic. 



3. 157. Gunshot Fracture of the Shaft of the Humerus. — 



Portion of a humerus — macerated, showing the effects of the 

 above. 



The patient was a soldier who fought at "Waterloo. 



There has evidently been septic osteo-myelitis. A portion 

 of the bone, smoother and whiter than the rest, has necrosed. 

 At other places new bone has been thrown out from the broken 

 surface of the bone, from the periosteum, and in the medullary 

 cavity. F. P. C. 204. 



Presented by Professor John Thomson. 



3. 158. Old-standing" Gunshot Fracture of the Lower End 

 of the Humerus. — Lower end of a left humerus — macerated, 

 showing the effects of the above. 



The wound was received at Waterloo by a soldier who fought there. 

 He sank exhausted by hectic fever and diarrhoea thirteen months after the 

 battle. 



This specimen was figured in Hennen's " Military Surgery," 

 2nd edition, plate i. fig. 3, as an illustration of the bad effects 

 of the impaction of a fragment of bone into the medulla ; also 

 of Nature's attempt to bridge over the injured part by new bone 

 formation. The features of the specimen would, however, be 

 now explained by septic inflammation of the bone and soft 

 parts, with subsequent reparative changes.
