Abstract
DURING the past thirty years or so, intensive investigation of cellulose by various physical methods has directed attention repeatedly to the possible existence of supermolecular units of structure ranging from ‘fibrils'1 some 0·4 µ in diameter and of indefinite length to small spherical or ellipsoidal particles of diameter up to 1·5 µ2.
