Abstract
WE have recently been carrying out experiments on the diffusion of solutes across the interface between water and organic solvents, using an optical method. In a cylindrical glass cell (2.4 cm. diameter) the meniscus is about 0.7 cm. deep, convex towards the water. This curvature would complicate the interpretation of diffusion measurements and would give a region on the organic solvent side where beams of light could not pass through undisturbed. If the tube is greasy, the meniscus is inverted.
