Abstract
IN determining the size distribution of particles in samples of finely ground barytes, difficulties have been experienced in determining experimentally the ultimate balance reading corresponding to sedimentation equilibrium1. It takes an inordinately long time for equilibrium to be attained, and even then this does not necessarily represent complete sedimentation of all solid particles. Consequently, even at equilibrium the balance reading (Sā) will be less than the theoretical maximum reading corresponding to the weight of solid introduced (Sm).
