WITH his customary lucidity, Prof. Elliot Smith has presented, in the Royal Institution discourse which accompanies this issue of NATURE as a special supplement, an account of the present position of his researches in organic neurology in conjunction with the results of other workers, particularly Campion and Le Gros Clark. The result is not only a notable step forwards towards an understanding of the complex temporospatial relationships which from one poiivt of view are designated the brain and its related Mechanisms., and from another mental function it is also an effective counterblast to recent efforts, preinturely understanding of sensory integration in forms of merely clinical application. It is to lie hoped that the danger to true progress in neurology resident in this efftorts has been, if not averted. at all events wthftood fo tbf time being.
