SYNOPSIS Radial striations are shown to be present as fixed appearances in the refraction rings of submerged bubbles in diverse media, and to be due to aerosol particles at the surface. They are shown to be of multiple origin, being composed of brighter parts of concentric rings of light which may be produced in this usually dark zone. Possible causes of these phenomena are discussed in relation to the bubble surface. It is concluded that the bubbles are surrounded by thin layers of static material of different refractive index from the bulk of the liquid, and that the “radial striations” are due to multiple image formation by the two interfaces produced.
