of experiments to report, which seems to me to prove beyond the
possibility of a doubt the correctness of my position. These
experiments were made with the apparatus shown in Fig. 10. The
subjects proceeded precisely as before. The finger-tip was passed over
the filled space, and then out over the open space, until an
equivalent distance was measured off. But while the subject was
drawing his fingers over the spaces, the block _A_ was moved in either
direction by means of the lever _B_. The subjects were all the while
kept ignorant of the fact that the block was being moved. They all
expressed great surprise on being told, after the experiments were
over, that the block had been moved under the finger-tip through such
long distances without their being able to detect it. The block always
remained stationary as the finger passed over one space, but was moved
either with or against the finger as it passed over the other space.
