Abstract
IN a recent survey with an interferometer at 2,695 Mc/s1, it was found that most of the quasi-stellar radio sources which have large fluxes at this frequency are unresolved, indicating sizes which are less than 3″. The survey has now been extended to include all objects in Wyndham's list2 that are possible quasi-stellar objects, as well as a few other sources with well established identifications. Most of the sources in the second survey have smaller fluxes and are resolved, with sizes ranging from 5″ to 70″.
