The thickness of the film of liquid falling on a sphere has been measured in the presence and absence of a film on the surface and fair agreement has been obtained with theoretical relationships for both these cases. Some comments are made on "entrance" effects related to the way in which the liquid is led onto the top of the sphere. The thickening of the film which occurs when there is a surface film can be used as a sensitive means of ensuring that the surface of the sphere is wholly active in gas absorption. It is shown theoretically that the rate of absorption is not very sensitive to the entrance and exit effects.
