• "The Nonspherical Analysis" by Kurki-Suonio and Ruuskanen (Ann. Acad. Sci. Fennicae A VI 358 (1971)) is applied to the structure amplitudes of CaF_2 measured by Togawa (J. Phys. Soc. Japan 19 (1964) 1696) with weak reflexions of Weiss, Witte and Wolfel (Z. phys. Chem. 10 (1957) 98). Earlier conclusions of the average compression of the Ca ion and the extension of the F ion are confirmed. The nature of the atomic non-sphericities coannot be verified reliably from the mere data of Togawa because of their incompleteness, while the combined data indicate a slight cubic deformation of fluorine corresponding of angular displacement of about 0.2 el per fluorine atom in total at an average distance of about 1.0Å from the fluorine nucleus.
