A bstract This report covers a review and correlation of previous theoretical and laboratory research of falling particles with some data on the settling of quartz and muscovite grains of variable shape and particle size in water, with and without vacuum and alkali treatment. Stokes’law and Richards’data were checked. The greatest factor which produced a variation in rate of fall was incomplete dispersion of the particles. Complete dispersion with alkali gave the best correlation with theoretical calculations.
