Recent simulations, as well as weak lensing and X-ray data, indicate that gas is a good tracer of the total mass in clusters. The constancy of the gas fraction f, in clusters of galaxies can thus be used as a novel distance indicator &4"'fi,,/fi0. Assuming spherical symmetry and hydrostatic equilibr

A short description of the theoretical basis of the method is given, followed by the results of the diameter observations of four giant stars obtained in 1964 and 1971 With the 30-cm refractor of the.Lohrrnann Observatory. The angular diameters found are as follows: 7 Gem (IvI3III) ofoogg \* 0:0015;
