Abstract
The dimensions, forms and, where possible, the position angles of 4287 galaxies, down to a limiting diameter of 36″, have been measured on 28 prints from the Palomar Sky Survey, in various areas of the northern galactic hemisphere, and in Eridanus. In all areas, certain ranges of position angles are much more favoured than others. There also appear to be correlations between position angle and distance, and between position angle and projected shape, in support of the suggestion, made in the writer's 1964 paper, that the principal planes of a group of spirals tend to pass through a fixed point in space. The proportion of narrow spindles, to round or nearly round spirals, was also found to vary, from area to area, in a marked degree.Keywords
