%X In a recent paper, Sandage (1961) considers the problem of using the angular diameters of extra galactic nebulae in order to decide between various world models. In his approach Sandage uses formulae derived from the field equations, as given by Mattig (1958), under the assumption that both the pressure and cosmological constant are zero.
