Abstract : Unique experiments are described showing: (1) an apparently paradoxical behavior in the rising of gas bubbles in smoke and in the subsidence of miniature smoke clouds in a gaseous atmosphere, and (2) the movement of the aerosol particles of a cloud from the gaseous boundary of the cloud into the cloud. It is concluded that: (1) An unexplained force probably attracts the aerosol particles in an aerosol cloud. (2) The observed, apparently paradoxical, behavior of the aerosol cloud is caused by an ordinary, diffusional exchange of gas molecules between the cloud and the adjacent gas. (Author)
