The preliminary study of interconnected galaxies has yielded a few results which promise to be of importance for astrophysical theory. Luminous connections of various types were described in the preceding. These connections occur rather indiscriminately between galaxies of all types. Most, but not all, of the intergalactic bridges are rather blue in colour and they seem to derive their luminosity from stars. So far no emission lines have been found in the spectra of long bridges. The fact that many thousands of extended luminous intergalactic formations have been found on plates taken with 48-inch Schmidt telescope greatly strengthens the theory that because of encounters among onents in some of the multiple galaxies needs to be explored thoroughly before one may hope to arrive at a satisfactory theory of the kinematic and dynamic characteristics of the large scale aggregates of matter in the universe.
