Reexamination of the hydrodynamic theory used by L. Hocking as the basis for his cloud droplet collision efficiency calculations has shown that his results are in error when the droplets are close together. An improved hydrodynamic theory is discussed, based on published papers by Stimson and Jeffery, Maude, and upon recent work by the present author not yet published. Preliminary collision efficiencies using the improved results resemble Hocking's for droplet radii greater than 20 microns, but fail to show the 19-micron cutoff he reported. 12 pp. Bibliog.
