The phenomena of sound present many interesting features and diffraction is not the least. The writers have been able, by an extension of Rayleigh's theory, to determine the effect in the neighborhood of a rigid sphere produced by a source of sound located on that sphere. One of the results of this theoretical investigation is the establishment of the variation of the intensity of sound with the distance from the center of the sphere. The computations necessary for approximate numerical results are tediously long, and those given herewith are merely those that were readily available in other investigations of the writers.
