Fig. 39—Radio-Vitant Applicator for the local application of radiant light and heat. In reducing local and superficial inflammation, the thermic action ofthe carbon filament of high candle power, added to its luminous andtonic qualities, renders it more efficient than the more luminous but lessthermic tungsten filament, or than the action of convective heat. Tungsten filament, either in the vacuum or nitrogen-filled globe, givesa whiter light, and produces less heat. Its luminous penetration appearsto be greater than that from either of the other sources. Radiant energyfrom the tungsten filament as a source, is equal in therapeutic value,to that from the carbon, except in inflammation, and in the effect uponthe lungs and Fig. 40—Abdominal application of radiant lightand heat. Electro-Medicine, Electro-Surgery and Radiology 95 Therapeutic Application Electric Light Bath The electric light bath is cither of a cabinet or reclining form, fittedwith a number of incandescent lamps. These lamps are wired in sec-tions, enabling the operator to switch on all or only some of the lamps,and thereby adjust the temperature of the bath and concentrate thelight according to the patients constitution and the state of his healthat the time. The electric light bath increases the surface circulation, dilates lym-phatic vessels, and at the same time causes a diminution of the arterialpressure and augmentation of the pulse frequency. Owing to the remarkable stimulus of light rays, this bath produces al-most the same sudatory effects with a thermometer registering 195 de-
