在赤纬+50 °至_50 °的范围内，共发现104个离散源。并将各源的位置和通量密度与以往的调查结果进行了比较。观测到的分布表明了Brown和Hazard（1953）发现的所有亮源在银河赤道的集中度，以及米尔斯（1952 a，1952 b，1952 c）发现的亮源在赤道的集中度。在南银河半球，一个新的微弱光源的集中是显而易见的。有强有力的证据表明，在银河赤道周围20°区域以外的源偏离了均匀的各向同性分布。提出了10个源和可见天体之间的鉴别;其中7个是暗源和照相星等a-的河外星云：Jout 12· 5，3个是银河星云。后者之一是新星阿奎拉1918的膨胀壳。
One hundred and four discret~ sources have been found from a survey covering declinations +50 to __ 50°. The individual sources are compared in position and flux density with those of pr~vious surveys. The observed distribution shows the concen· tration of sources of all brightnesses to the galactic equator found by Brown and Hazard (1953) and the concentration of the bright sources to the equator found by Mills (1952a, 1952b, 1952c). A new concentration of faint sources is evident in the southern galactic hemisphere. There is strong evidence for departures from a homogeneous isotropic distribution for the sources outside a 20° zone about the galactic equator. Ten identifications between sources and visible objects are suggested; seven of these are between faint sources and extragalactic nebulae of photographic magnitude a-:Jout 12· 5, and three with galactic nebulosities. One of the latter is the expanding shell of Nova Aquila 1918.
