Professor Hers-chell C. Parker, of Columbia Univer-sity, New York, and Mr. Walter , of New York, sought to improve the Edison lamp, and their experiments]iroduced the Helion. In cabinets, side by side at the HelionLight booth, was shown the HelionLight along Avith the ordinary lamp, therays of each falling on a variegatedbackground. The marked difference inthe intensity of the two lights promptedthe spectator to inquire the reason. Itwas simply due to the difference in thefilament. Messrs. Parker & Clark, ex-perimented ten years on the carbonfibre used in the Edison lamp. Theyfound that a combination of elements, ofwhich silicon forms a prominent part,. The Helion Electric Lamp. with a small strand of carbon as a basis,made into a form of filament, gave alight many times more powerful than:he Edison lamp and at a reduced the difference in the color of thetwo lights. The light of the ordinaryelectric lamp is yellow, and, consequent-ly, articles on which this light falls, donot show in their original color. TheHelion light is pure white, and showseverything in the same shade as theyappear in the light of the sun. Helion Electric lamps reduce the costof electric lighting to one-third of thepresent price by requiring only one-thirdthe current used with the ordinary CANADAS GREATEST FAIR. 133 lamp. At the same time, a much morepleasing light is obtained. The advan-tages of electric lighting are acknowl-edged by all, but heretofore it was im-possible to reduce the cost of produc-tion to that of gas. The advent of theHelion light will reduce the cost belowthat of coal gas, and make this ligh
