Experimental details are presented for two series of short‐range diffusion experiments in which glass spheres were emitted from continuous and instantaneous sources. Observed standard deviations of cross‐arc deposits were compared with predictions. For instantaneous sources these standard deviations were fairly well forecast by the simple method of Smith and Hay (1961), although predictions were improved by use of the most appropriate value of β, a Lagrangian‐Eulerian scale factor. Continuous source cross‐arc standard deviations were well forecast by Hay and Pasquill's (1959) method.
