Necrosis from Septic Wounds. 277 



new bone and a rarified portion of the original shaft. Much 

 new periosteal bone has been thrown out on the surface all 

 round. The case has probably been one of compound fracture.

6. 191. Septic Osteo-myelitis, Necrosis, and Enlapgement 

 of the Tibia following- Amputation. — Upper third of a 



right tibia — macerated, illustrating the above. 



A considerable portion of dead bone is seen running up 

 upon the inner side, and its lower end has been part of a sawn 

 surface. It has been separated, but has been fixed in position by 

 partial development of new bone round it. The rest of the 

 shaft of the tibia shows new bone growth on the surface and 

 absorption within. Probably two other large pieces of necrosed 

 bone have been removed from the gaps on the front and outer 

 sides. B. C. I. 5. M. 32. 



6. 192. Septic Osteomyelitis, Necrosis, and Enlargement 

 of the Tibia following" Amputation. — Upper three-fourths 



of a right tibia — macerated, illustrating the above. 



There is a partial development of new bone on the 

 surface, with a deficiency in front and on the inside, from 

 which a sec[uestrum has probably been removed. The exposed 

 portions of the original shaft are rarefied. G. C. 985. 



6. 193. Septic Osteo-myelitis, Necrosis, and Enlargement 

 of the Femur following Amputation.— Greater portion 

 of the shaft of a femur — macerated, illustrating the above. 



The bone has been greatly thickened, and the surface 

 presents the usual characters of new periosteal bone formation. 

 There are four cloacal apertures, through some of which dead 

 pieces of bone can be seen. A necrosed fragment has evidently 

 been removed from the centre of the lower end and from the 

 front of the upper end. B. C. i. 5. M. 30.
