London has been informed by telegraph that Mr. Edison has
made another advance towards the use of the electric light for domestic purposes. His friends say that ho has found in car- bonised cardboard a better medium than platinum for conveying the light, that he has made it perfectly steady, the carbonised cardboard not being destroyed, and that one small gas-engine will keep fifty lamps in good work. He has also invented a meter which registers the light supplied,----or, rather, the consumption of copper in developing the electricity. No hint is given of the cost, but Mr. Edison proposes to light up Menloo Park, the village in which he resides, on New Year's Day. Many more details must be forwarded before any opinion can be formed as to the chances of the light in competition with gas, but it may be observed that every month some advance is recorded in elec- tric lighting. No one, however, has yet got rid of the ghastly whiteness or moonlight effect of the light, so noticeable on Waterloo Bridge.
