Title supplied by cataloger. Pictured is Dr. Milton Metfessel of the University of Southern California, demonstrating a new device called a strobo-camera, which "photographs" songs of birds and thus records range and vibrations of their voices for scientific analysis. The singing birds cause a neon light to respond with light vibrations. These are picked up by the apparatus pictured here, and recorded on a whirling disc with a stream of dots. Photograph dated March 12, 1934.
