Atlas of interacting galaxies, part II and the concept of fragmentation of galaxies.

This is a further publication of the photographs of some of the 1500 interacting galaxies found by the author on the Palomar Sky Atlas, recognized and described by him in the "Morphological Catalogue of Galaxies" mostly before 1964. They are given with a magnification of 30 times. Some of the photographs have been taken from the excellent large-scale photographs of these objects made or collected by Arp. This is also the case for some of the objects published in 1959 on a smaller scale in part 1 of our atlas and since then studied in more detail. These are identified by numbers below 356. Altogether, 700 photographs of 600 objects are presented here, of which 500 photographs are reproduced for the first time, although nearly all were already found and recognized and described long ago in MCG. it is essential that the images are arranged here and discussed from the point of view of fragmentation of galaxies and compared to the models of the theory of tidal perturbations. Key words: atlas - interacting galaxies - evolution of galaxies - morphology of galaxies
