Healing after Syphilitic Necrosis, 311 



6. 274. Syphilitic Disease of the Skull— healed after Loss 



of Substance. — Portion of the right frontal and parietal 

 bones of an old person — macerated, illustrating the above. 



On the outer surface there are numerous smooth excava- 

 tions and tubercles, and at one place a small perforation, with 

 rounded margins. On the inside the changes are very slight, 

 merely some irregularity near the perforation. The coronal 

 suture is obliterated except at a small place near its lower end. 

 This seems to be a case where the disease had completely 

 subsided. Formerly described as " a caries of the left parietal 

 bone." G. C. 370. 



6. 275. Syphilitic Disease of the Skull— healed after Loss 



of Substance — Skull-cap of an adult, with permanent frontal 

 suture — macerated, illustrating the above. 



On the right parietal bone, near the vertex, is a circular 

 depression, one and a half inches in diameter, with a sinuous 

 rounded margin and irregular base, which has been smoothed 

 over. This is as if a superficial sequestrum had been separated 

 some time before, and the part had healed over. In front of 

 the left parietal eminence is a shallow depression, with a 

 base, which is at one place smooth and at others rough, as if 

 the disease have been in process of cure. The interior of the 

 skull shows some marks of increased vascularity.

6. 276. Syphilitic Disease of the Skull— healed after Loss 



of Substance. — Portion of the front of a calvarium, with 

 permanent frontal suture — macerated, illustrating the above. 



There is a depression, one and a half inches long by one incli 

 broad, between the frontal eminences. Its margins are bevelled 

 off and smoothed over, and its base, Avhich is also smoothed
