that obtained by the statistical method of Hauptman & Karle (1953, p. 50). The connection between (17) and a Patterson-Harker section has already been pointed out by Vand & Pepinsky (1953); it is mentioned here for the sake of completeness. Once again, the result will be of practical value only for simple crystal structures, or when the asymmetric unit includes some small number of approximately equal heavy atoms. Similar results can be found for space groups which do not have a centre of symmetry, provided that they project to give a centrosymmetric plane group. For example, for space group P2
