 after death no signs of affection of the brain could be discovered'* 

 (Sir Charles Bell). 



The surface of the greater part of the frontal bone is 

 roughened by the opening out of vascular pores, and the smooth 

 dead portion of bone is surrounded by a groove formed by

 removing the calvarium. B. C. 1. 2. M. 14. D. 



3.41. Compound Fracture of the Skull— Septic Osteo- 

 myelitis — Death. — Portion of a cranium three weeks after 

 fracture — macerated — with a dead piece in process of separa- 

 tion. 



The dead piece is smooth and polished. The granulations 

 have begun to cut a groove round it, and the adjacent bone is 

 roughened by inflammation. The trephine has been applied.

3. 42. Compound Fracture of the Skull— Septic Osteo- 

 myelitis — Death. — Portion of a cranium after fracture,, 

 dura mater ^V^ situ — dried. 



Part of the bone is in process of separation. The trephine 

 has been twice applied. The cause of death has probably been 

 septicsemia or pyaemia. G. C. 1155.

3. 43. Compound Fracture of the Skull— Septic Osteo- 

 myelitis — Death. — Portion of the right frontal and parietal 

 bones — macerated — from a case of compound fracture. 



There has been extensive ulceration and necrosis, and
