1. The object of the following work is to make some progress with the mathematical representation of the motions which go to compose natural light. 2. It has always been recognised that interference phenomena forbid us to regard any natural radiation as consisting of an unending train of simple waves, such as may he represented by sine functions. At the same time, the equations of optics find their simplest solution in circular functions. It is desirable to enquire how far we may resolve a natural luminous motion with a sum of simple wave-trains by means of Fourier’s “Theorem of Double Integrals.” This procedure was first suggested by Gouy.
