During March and September 1960, observations were made with the Caltech interferometer of 739 sources listed in the two catalogues of Mills, Slee and Hill^1,^2. The primary purpose of the investigation was to provide this observatory with a 960 Mc/s "finding list" for future measurements of source sizes and precise positions. The area covered in these observations was: 0: -50° to -20° a: 17 to 5 hours o: -20° to +10° a: O to 24 hours. In general, the observations were restricted to sources in the MSH catalogues whose flux density at 86 Mc/s was greater than 15 x l0^(-26) watts m^-2 (c/s)^-l. All sources down to this level were examined with the exception of those in the region 18h to 24h, between o^o and -10° . Most sources were observed near transit for at least four or five minutes at the position given in the Sydney catalogues. This allowed us to observe one 10-degree declination zone each night. The flux density of each source was measured relative to the standard source Hydra A ( 09-14), which was observed each night when possible. When Hydra A was not available, 22-11 was used as a secondary calibrator. All observations were made at night to avoid effects of solar radiation.
