Hypnoscope

The hypnoscope ( Greek ) is an apparatus designed by Gustav Wilhelm Geßmann at the end of the 19th century , with the help of which one supposed to find out whether a test person could be easily hypnotized or not. The effectiveness of this procedure has not been proven.

The apparatus consisted of four horseshoe magnets arranged in a ring , the 8 poles of which converge against a narrow space into which the subject's index finger could be stuck. The peculiar sensations of the test subject should then provide information about their ability to hypnotize.

Johann Ochorowicz had previously specified a similar instrument .
