Crown bald, with a slight fuzzy growth of short hairs. Scalp slightly adherent to calvarium; latter of usual thickness but denser than normal. Dura adherent to calvarium in region of vertex; dura not remarkable. Sinuses normal. Arachnoid villi moderately developed. Pia mater a trifle thickened and rather evenly throughout the cerebral portion. Linear sulcal markings are remarkable for their absence. The wall of the cerebellomedullary cisterna is thick and opaque. The most prominent pial thickenings are over the cerebellum. These are linear or may show feathery out-growths and are seated over the sulci, particularly in the neighborhood of the fissure and about the great cerebellar notch. They correspond fairly well with the focal variation in consistence of underlying tissues noted below.
