John Bellamy Taylor, consulting engineer for the General Electric Company's research laboratories at Schenectady, New York, will give a public lecture and demonstration on "Audible Light" at 7.30 o'clock on Monday in 110 Pierce Hall.

Mr. Taylor deals mainly with one type of physical phenomenon, the translation of light into sound. To illustrate this he will conduct demonstrations in which speech, song, and instrumental music are carried on a beam of light and will cause the photo tube to "see" light from various sources. In this experiment, light instantly sets up within the tube feeble electrical currents, which, amplified by vacuum tubes, are converted into sound waves and heard through a loud speaker connected to apparatus.

Mr. Taylor has been interested in acoustics and music for a long time, and he has done important work in the field of talking moving pictures, as well as in the co-ordination of telephone systems with power transmission lines. He is experienced in the production of seemingly astounding effects with the photoelectric cell. In his use of vacuum tubes, he will give a working demonstration of one of the most significant of the new tools that have come with the "electrical age." The address will give a clear indication of the certain possibilities which reside within the newest types of vacuum tubes.
