Dog D showed degenerationin the columns of GoU, more marked on one side, butdog E gave the most important results, and the follow-ing descrijjtiou is from the sections obtained in this case. Axis cylinders in tlie periphery of the anterolateral and pos-terior columns were found here and there considerably swollen:some were of large size: swollen cylinders were seen in the 10 root entrance zones of the posterior columns, but otherwise notin the posterior columns except near the peripliery.
