Journal of the American Medical Association, May 5, 1900, p. 903. 294 METHODS OF APPLICATION AND THERAPEUTICS MAGNETISM At this time there is no evidence that exposure to the magnetic forceproduces any physiological effect upon the human organism. Petersonand Kennelly experimented in Edisons laboratory with exceedinglypowerful magnets. As a result of these they concluded that the human Fig. 272. Vibrator. organism is in no wise appreciably affected by the most powerfulmagnets known to modern science; that neither direct nor reversedmagnetism exerts any perceptible influence upon the iron contained in MAGNETISM 295 the blood, upon the circulation, upon ciliary or protoplasmic move-ments, upon sensory or motor nerves, or upon the brain.^ The application of magnets to areas of hysterical sensory paralysishas been attended with good results, but in these cases the cure is dueto suggestion and not to any virtue in the magnet itself. The obser-vations made above apply to the use of permanent magnets. Anotherform of magnetotherapy lately introduced is the so-called permeatingelectricity method of E. K. Mueller. In this the patient is exposed toan undulating magnetic field produced as follows: The apparatusconsists of a wire spiral of about 200 windings, which is traversed by acurrent of
