S., male, fifty-three years old. Disturbance of roentgenogram showed the skull vault to be of normal contour, 5 The hypophysis was shallow and widened at the top. The dorsum INTRACRANIAL DISEASES 199 was completely gone, except for two short points. The anterior clinoidprocesses showed no change except shortening. (See Fig. 76.)
