The literature on cerebral hemorrhage of the new-born concerns itself mainly with the size, source and mechanism of the hemorrhage, with but little attention to the reaction of the meninges and the brain. It was the latter phase of the condition that formed the basis for our investigations. In order to evaluate our work properly, we studied the brain and meninges grossly and microscopically. We also studied the question of the relation of atelectasis to intracranial hemorrhage. Special attention was paid to the occurrence of cerebral hemorrhage in three infants delivered by cesarean section.
No attempt is made to review the literature on cerebral hemorrhage of the new-born in detail. The recent monograph of Ford1 and the papers by Warwick2 and Ylppö3 give the more important references on the subject. Only papers dealing directly with the phase of the subject studied by us will be referred
