The effects of the diffusion of light by small particles may broadly be divided into two classes, according as the linear dimensions of the particles are large or small compared with the wave-length of the light. In the present note only the first of these classes is considered. Rain, cloud and fog all consist of small spheres of water distributed at random in the air, and with very different degrees of concentration. Their linear dimensions may exceed a tenth of an inch, in the case of rain, or be less than a thousandth of an inch in cloud and fog.
