This book is the record of a symposium on the physiology of the spinal cord given at a meeting held in London from Feb. 26 to 28, 1952. The fifty or so participants included, among others, Adrian, Barron, Bremer, Bülbring, Creed, Dale, Eccles, Feldberg, Liddell, Matthews, Romanes, Skoglund, and Young. They surveyed the more recent advances concerning the functioning of the spinal cord. Of current clinical import there is little information save perhaps on the effects of various pharmaceutical agents on cord activity, which may conceivably be of value in dealing with spasticity. The large clear printing on nonreflective paper, the excellent diagrams, and author and subject index make a fine, compact volume that should be most useful to the neurophysiologist and to those doing clinical research in neurology.
