Fig. 67.—Treatment by the effluvation method. The eondenter electrode, B, is in connecticn•with the top of the resonator. Patient is seated upon an insulated platform, holding the electrode, A,which is the other pole, from the outer side of the Leyden jar, L J. (By grounding the outer side of theLeyden jar, A, the patients insulation is unnecessary and better effluvation is attained.) ,S. M. is thespark-gap. HIGH-FREQUENCY CUREBNTS. 129 affirms that currents of ten times less intensity would be extremely dan-gerous if the frequency were decreased from 500,000 to 1,000,000 persecond, to 100. Tesla inclines to the belief that the harmlessness of thesecuiTents is due to their lack of penetration of the body at the point ofcontact of the electrodes, but that the current traverses the subject in apath perpendicular to the skin and equally over the entire surface.DArsonval declares that motor and sensory nerves are so constituted asto respond to vibrations of a certahi frequency, studyi
