Abstract

Attention is drawn to the differences in the relative intensities of the reflections of deerite measured on a Guinier photograph and those obtained from diffractometer data (Langer et al., 1977), which were probably collected without taking adequate precautions to reduce the orientation effect. Powder data for deerite, which are in conformity with the structure, are presented.
