Light That Is Ideal.

For interior illumination it is of decided advantage to have the rays of the lamp directed up to the light colored celling and then reflected below. This makes a light which is almost ideal, but in, lamps designed for street illumination this is not to be desifed, for such rays are lost entirely. The members of the New York section of the Illuminating Engineering society recently had their attention called to a new device which has been invented by Dr. Clayton H. Sharp of that city, who has devised a reflector consisting of a pair of parabolic mirrors arranged to throw the rays in the direction of the street, so that all the light will be used to tbe best advanage. The claim is made that instead of haying the streets lighted in spots, as at present, a continuous degree of illumination Is provided.
