Hereagain the result was, at first, an utter discord inthe spatial reports of the two senses. The wholebody was seen in a different place from where it wasfelt; it was in fact projected at a right angle tothe front and several feet away, as indicated bythe dotted outline in Fig. 31. But the constant sight. .vl -O, Fig. 31. — Arrangement of mirrors for projecting the body intoa false direction and distance. of the feet and hands, for instance, tended to pullthe feeling of these members over into the placewhere they were seen, so that, on the third day,there were occasions, especially during rapid walk-ing, when no conflict was felt as to the place ofthe various impressions. Such a harmony, it mustbe confessed, was only occasional; but that it couldcome at all, and particularly that it came more for-cibly the longer the experiment was tried, shows Spatial Harmonies and Discords 149 clearly what the harmony of the tactual and the visual space-world consists in.
