Note 524 — Chapter XXVII

I myself verified many of the above effects of the magnet on a blindfolded subject on whom I was trying them for the first time, and whom I believe to have never heard of them before. The moment, however, an opaque screen was added to the blindfolding, the effects ceased to coincide with the approximation of the magnet, so that it looks as if visual perception had been instrumental in producing them. The subject passed from my observation, so that I never could clear up the mystery. Of course I gave him consciously no hint of what I was looking for.
