Thus, a discharge will not be as marked from a flat part of the body asit will from some bony prominence, therefore we must be careful aboutdrawing charges from the smaller parts of the body, as there the conductivityis lessened, and the effect is more marked. This modality therefore, followsthe same law of density and diffusion as do the other forms studied inprevious pages. 106 THE ELECTRO-THERAPEUTIC GUIDE What can be said of static polarity

The same polar effects are manifested here also, in that the positive issedative and anodyne, and the negative is irritating and stimulating. What is the difference between static and faradic induced cwrrents? The static induced current is not of the alternating character of thefaradic induced current. Instead, it is a undirectional current, but inter-rupted at the same rate that the primary static current which induced it, isinterrupted. Of what use is the hygrometer?. The hygrometer is a little instrument which is placed in the case of thestatic machine. It indicates the percentage of moisture in the air, and tellsthe operator why his machine works badly, and when to dry it out. What is the physiological effect of static electrification? The static current produces no chemical effect in the tissues, it acts asa general tonic and stimulant to the nervous and circulatory systems. Itwill increase the circulation, improve nutrition, assist digestion and assimi-lation, promote absorption, quiet, refresh and invigorate the nervous system. On account of its great voltage it puts the surrounding air in a state ofgreat stress, liberating allotropic oxygen, which in the form of nascentozone is inhaled or absorbed through the skin and enters directly into thecirculation, thus increasing oxidation.
