A bstract A simple method is described for measuring the complete range of particle sizes in a clay, with equipment which can readily be used in the plant‐control laboratory. The usual Casagrande sedimentation method is extended to lower limits of size by swinging the suspension in a long arm centrifuge by which means particles can be measured as small as 0.05 micron. Distribution curves are shown for several types of clay and the precision of the results are discussed.
