REPORT OF CASE
—J. E. R., a white man, aged 50, had a stroke and died on his way to the hospital. Investigation revealed that he had a sister, but she could not be reached. He had been a drifter. The body was examined in the department of anatomy of the University of Arkansas School of Medicine.
—The brain was removed in the routine manner, shortly after completion of the embalming. The appearance of the specimen is shown in the figure. No evidence was found in the skull that there had been an injury in the temporal region. The defect did not resemble a lesion from injury or disease. The surface of the cortex had a normal appearance. By examination of the basal view of the brain in the figure (A) the normal right side can be contrasted with the defective left side. The left temporal pole
