In the article by Dr. Charles Frazier, which appeared in the August issue of the Archives of Neurology and Psychiatry, the tracts in the illustration of the cord, on page 139, were incorrectly outlined. This illustration was inadvertently sent with the manuscript. The correct illustration appears in the reprint, a copy of which may be secured by sending a stamped, addressed envelope to the author.
The author also calls attention to an error in his manuscript: "latterly I have chosen the sixth cervical segment." This appears in the nineteenth line from the top of page 140. It should read: "latterly I have chosen the sixth thoracic segment."
