✦ Synopsis

Additions to membership since last report, IO. The standing committees of the year I914-I5 were announced. Following the meeting of the Institute for the transaction of this business, a joint meeting was held with the Illuminating Engineering Society.

Dr. George A. Hoadley, chairman of the Philadelphia Section of the Society, introduced Dr. Herbert E. Ires, of Philadelphia, who presented an interesting communication on " Artificial Daylight."

The speaker discussed the problem of producing artificial light of daylight color and quality.

Various systems of color measurement were described as applied to daylight and artificial light.

Artificial daylight was produced by several methods, and its use in the industries considered at length.

An artificial daylight producer was exhibited which can be used with the Welsbach light, or, with a slight modification, with the tungsten electric lamp. A new glass was also shown for the first time, which makes possible the converting of the light of the gas mantle into true daylight.

Lantern slides were used to further illustrate the subject. In the discussion which followed the presentation of the paper, Messrs. Bond, Henderson, Calvert, Hornor, and others participated.

After a vote of thanks to the speakers, the meeting adjourned. R. B. OWENS,
