markedly roughened and shows a large number of flattened wart-like ex- 

 crescences, varying in diameter from that of a pinhead to 1 cm. They 

 are especially abundant along the median line. The vascular grooves are 

 present but somewhat obscured by the hyperostoses. 



The base of the skull, from the inside, shows in the anterior fossa 

 slight increase of convolutional markings. The cribriform plate of the

ethmoid is small and contains two warty excrescences. The fenestrations 

 on the right side are encroached on by exostoses ; on the left side they are 

 little changed. (Figs. 8, 9, 10, 11, 12.) The posterior part of the floor 

 of the anterior fossa is moderately elevated in the median line (from 

 pressure of the enlarged hypophysis). 



The middle fossa is markedly altered. Its anterior margin is normal 

 in its lateral portions, but elevated and sharpened 1 in its middle, sellar
