    a very complete degeneration of the posterior columns, with a sharply defined peripheral band (of varying breadth) in the other columns, well illustrating the circumferential distribution of the long tracts. The anterior roots coming off from the lower part of the isolated piece show no degeneration, so that their fibres have a very local origin compared with the connections of the posterior roots. The degeneration in the isolated portion of cord was less at the end of one month than at the end of six months, so that apparently degene- ration increases with time. After longitudinal division of the cord, besides a tract of degenera- tion just external to the posterior roots, there is an ascending degenera- tion at the anterior border of the cerebellar tract. Injury to the anterior cornu of one side of the cord causes a degeneration in the anterior root of the other side, so that some fibres of the anterior roots come from the opposite half of the cord. The Marchi stain cannot as yet be accepted as yielding an absolutely unmistakable criterion for scattered degenerations. For permission to use the Laboratory, as well as for much friendly advice and assistance, I am indebted to Dr Sherrington, to whom I take this opportunity of acknowledging my thanks. Plate XIV.
