Show LIGHT OF COMING DAYS. A SclentUt Thinks Ffcosphoreacent Glow ViU gu.per9e.le Elef ttloltj. It seems hard ui believe that in a very few years the incandescent lamp, which we now regard as in many respects an almost perfect light, will be regarded as a'cruile makeshif t, which mankind availed Itself of while science stood on the threshold of the discovery of the perfect lumioant. Mr. Tfesla has shown (n his experiments an ideal form of electric lighting which would transcend in4ixury and convenience our present system of electric lighting by incandescent incan-descent lamps 30 far as the latter transcends tran-scends the oil lamps and tallow dips used by our near ancestors. Every drawing room would become an electric field in a continual state-of-rspidly alternating alter-nating stress, in which the occupants would live, experiencing no unpleasant effect whatever while -vacuous tubes or phosphorescent globes, and tubes, without eare or attention, would shed a soft, ditfuse light of color and intensity intensi-ty arranged to suit the most luxurious fancy. Mr. Tesla's watchword is that the phosphorescent glow is the light of of the future: he hints at artificial auroras au-roras spreading from the summit of towers of hithenojundreamt height.and he has, at all events, got as far as producing pro-ducing in the air. at atmospheric pressure pres-sure a glowing plane bounded by two rings about a foot and thirty inches in diameter respectively. Whether all his visions will be realized remains to be proved; there is no doubt that they are guiding him aright, .-' , |
