The investigation of eclipsing binaries for which the most reliable masses and radii can be obtained is continued with analysis of the systems WZ Oph, F8, VZ Hya, F5, and UV Leo, G2. New spectrographic orbits were determined for all three systems, and a photoelectric light curve was obtained for WZ Oph. Attention is also given to superficial physical effects in close binary systems which may have important consequences in their spectra, so that difficulties are encountered in attempting to evaluate with any degree of precision from the observations the fundamental physical properties of the component stars. Attention is concentrated on those systems for which the properties can be evaluated unambiguously. Problems of eclipsing binaries are stressed, with visual binaries referred to less prominently.
