infiltrated with pus, and the head has necrosed and formed 

 several separate fragments. This specimen illustrates septic 

 caries and necrosis of the cancellated tissue, with necrosis also 

 of the compact tissue. G. C. 982. 



6. 182. Septic Osteo-myelitis and commencing' Necrosis 



after Scalp Wound. — Calvarium (with permanent frontal 

 suture) — macerated, illustrating the above. 



A large, smooth area of what seems to have been necrosed 

 bone in an early stage of separation is seen on the front, 

 chiefly on the left side. There is a shallow line of demarcation 

 marked off round it. G. C. 912. 



6. 1 83. Septic Osteo-myelitis and commencing Necrosis of 

 the Skull after severe Scalp Wound.— Skull-cap- 

 macerated, illustrating the above. 



"This man had his scalp torn oif the skull. It was replaced. 

 Suppuration under the scalp followed, and he died finally of suppura- 

 tion of the membranes of the brain." 



The dead portion is smooth, and round it the bone is porous 

 from the enlargement of vascular channels. On the interior, 

 especially along the middle line, marks of increased vascularity 

 are visible. B. C. i. 2. M. 14. e. 



6. 184. Septic Osteomyelitis and Necrosis of the Skull, 



following" a Scalp Wound.— Left half of a calvarium— 

 macerated, illustrating the above. 



There is a small scale of necrosed bone in process of 

 separation upon the front of the parietal bone below the 

 temporal ridge. F. P. C. 477.
