In this article I shall deal with some acute cases of cerebral disease in which multiple lesions of vascular origin, electively localized in the cortical gray matter, form the most interesting part of, or even the entire, pathologic process. The etiology varies; in two cases toxemia of pregnancy was the probable cause; in one case encephalitis and in one case severe shock with fall of the blood pressure.
