An electron diffraction pattern of cotton cellulose recording over 70 reflections per quadrant out to the tenth layer line could be indexed on the basis of the Meyer & Misch [ Helv. Chim. Acta (1937). 20 , 232–244] model. The validity of the observations based on the reciprocal net a * c * when checked by constructing reciprocal net b * c * revealed that three reflections could not be indexed. No systematic absence of odd‐order 0 k 0 reflections was noted. The cotton cellulose, therefore, does not fall into P 2 1 space group.
