Results of two-element interferometer observations of 234 radio sources are given. The data were taken with the National Radio Astronomy Observatory's interferometer, operating at 2695 MHz, with five antenna separations from 10000 to 24000X. One-dimensional brightness-distribution models are presented for 184 of the sources observed. These models give the brightness distribution of the source projected on the interferometer's direction of resolution. Relations are sought between angular dimensions of the radio sources and other observable parameters, and observational selection effects which could give rise to such relations are discussed. On the scale of the available resolution, 2", only thirteen of the 234 sources observed had all fringe visibilities less than 0.05. It is found that the quasi-stellar sources with flat radio spectra are small in angtilar size compared with those with steep spectra, that the apparently bright ones are small compared with the fainter ones, and that the highly polarized ones are all unresolved. For radio galaxies the largest angular dimension apparently increases with increasing flux density and increasing polarization. The spectral indices and angular dimensions of radio galaxies show no relation. No relations were foundbetweenarameters of the bright- ness-distribution models and another observable parameter for the unidentifiesources.
