veneris formed upon his forehead, and, the integuments ulcerating, dis* 

 closed a dead and black portion of the bone. This portion, after some 

 mouths, came away. The caries extended, and a second portion was in 

 progress of being thrown off. The dura mater burst, and fungus cerebri 

 forming, the man sank into low delirium, with convulsions of the face, 

 and expired." 



The upper part of the skull shows at various places 

 roughness and irregularity, which seem to have healed over. 

 Occupying the greater part of the frontal bone are two 

 sequestra, with their surrounding grooves. The larger is on 

 the right side, and crosses the middle line below. It shows 

 signs of old-standing disease on its surface, and has been 

 completely detached. The smaller one on the left side has 

 similar marks on its surface, and is surrounded by a groove, 

 which below has penetrated through the inner table. On the 

 inside, near the vertex, there are marks of old-standing 

 vascularity, but near the necrosed pieces the roughness from 

 increased vascularity is greater, and has apparently been recent. 

 The process of necrosis has involved the inner table in both 

 places, but the area of necrosis is less on the inner than on the 

 outer surface. B. C. i. 7. M. 17.

with Necrosis of the Palate. — Skull and lower jaw of a 

 man who died from syphilis — macerated, illustrating the above. 



" In the month of May last (1824) I was requested by a gentleman 

 in town to visit the individual to whom this skull belonged, aud found 

 him lying on a couch, extremely reduced and emaciated ; the face and 

 upper part of the scalp covered with numerous blotches and incrustations, 

 one of which was particularly prominent, and projected like a horn over 

 the centre of the frontal bone. 



' ' Various superficial ulcerations and blotches were also conspicuous 

 on his body and limbs, but these he did not seem inclined to show me to 

 their full extent, as he appeared to have lost all hopes of cure, and con- 

 sidered me, I believe, as only visiting him from motives of curiosity. 

 The same idea rendered him very little communicative as to the history 

 of his complaint, and he seemed quite unable to give any distinct or 

 connected account of their progress. All I could learn from him was that 

 the disease had commenced by an ulceration on the penis, and destroyed
