6. 194. Septic Osteo-myelitis, Necrosis, and Enlarg-ement 

 of the Femur following" Amputation.— Greater portion 



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



The bone has been very much thickened, and the surface 

 is unusually irregular. There are numerous cloacal apertures, 

 and several pieces of dead bone are seen through them. The 

 disease has extended upwards nearly to the small trochanter.

6. 195. Sequestrum of the Shaft of a Tibia after Septie 

 Osteo-myelitis following" Amputation.— A large portion 



of necrosed bone, apparently from the tibia of an adult. 



The surface shows the usual pitting produced by granula-

 apparently produced artificially. A node-like irregularity is 

 seen towards the upper end of the specimen.
