The material to be presented is thought to be of interest for two reasons. First, it deals almost exclusively with the late permanent neuropathologic changes, and not with the earlier evidences of injury, which may be reversible. Second, the experimental method employed permits an accurate correlation between the late pathologic changes and the time of the circulatory arrest. Reviews of the neurologic changes produced by anemia of the central nervous system have been published by de Buck and de Moor,2 Gomez and Pike,3 Cannon and Burkett,4 Gildea and Cobb5 and
