The author has reviewed the literature in as great detail as possible, abstracting numerous case reports from the published work of previous authors. The method that he uses fails in that he has not digested the various reports, so that the reader does not receive a proper evaluation of the significance of any one. He attempts to use psychoanalytic methods in the study of forced movements, using the same methods that have been applied to respiratory difficulties in epidemic encephalitis. Just what can be obtained from psychoanalytic studies of organic diseases of the nervous system depends to a large extent on the individual point of view. Certainly, Jelliffe's ideas are of great interest, but his interpretation is still largely theoretical and requires more proof than he has advanced.
