This is no. 66 of the excellent series of monographs on neurologic and psychiatric subjects edited by Bumke, Foerster, Rüdin and Spatz. It is a veritable cyclopedia on the subject of birth palsies. It emphasizes the importance of the subject to a country the government of which is conscious of its racial-political responsibilities and wishes to make practical use of the scientific study of heredity. In the excellent historical review it is indicated that while Oppenheim treated cerebral infantile palsy and Little's disease in separate chapters, Freud had pointed out the lack of difference between the two diseases. Certain conditions formerly included in this group are now eliminated, namely, familial spastic spinal paralysis, familial diffuse sclerosis, the Pelizaeus-Merzbacher disease, Schilder's disease, amaurotic family idiocy and tuberous sclerosis. The greater part of the book is devoted to the problem of the relative importance of genetic conditions and birth trauma. Dr. Thums
