    was correctly localized often enough and under sufficiently clear conditions to show that the localization was a matter not of chance but of genuine and subjectively certain space perception. So much was accomplished for each subject, and the possibility of an ultimate perfection, if training were continued, seemed demonstrated beyond a doubt. Tables of figures can show very little here, for a test series usually contains errors that rarely, or never, occur in the regular experiments. Still it may be interesting to compare the localizations of the first day of inex- perience with those of the last day of training, and with those given after an interval of some months. The table is self-explanatory. (See Table XV.) We append also the summary of all localizations made in test series given to the three subjects in the whole course of the experimentation.
