LESSINGER, Centre of Advanced Study in Physics, University of Madras, Madras - 25, India (Received 3 December 1973) Corrections are given to Acta Cryst. (1973). A29, 717-720. The following printing errors have been noted in Swami- nathan & Lessinger (1973): (1) The equation on page 718 should read: VOP°INT AT°MdV= ~ ~h' ~ EhEh,Eh4~, • (2) The legend for Fig. 4 should read: OVA 0(010) E map (3) In Fig. 7, the atom labelled 0(5) should be labelled 0(3).
