A survey of 11 subdural haematomas is presented. In three cases it was clearly established that there was no evidence of trauma; in two of these cases an enlarged firm liver was !present, and in one of them the prothrombin time was prolonged. We suggest that abnormal clotting, resulting especially from liver disease which is so common amongst Rhodesian Africans may cause or contribute to the formation of subdural haematomas. The physical signs in chronic subdural haematomas are inconstant and patients with it usually present with, changing levels of consciousness with little or no signs. Pupil size, pulse and blood pressure seem to be of little value in 'leading towards a diagnosis or assessment of the severity of the underlying haematoma and examination of the cerebrospinal fluid has limited value.
