Strand (USA), George Teleki (Yugoslavia), and William van Altena (USA). All papers included in this volume were refereed.A significant part of them were not appropriate for publication as originally submitted, mostly for reasons of language. Some were therefore heavily edited. The papers originally submitted in Russian were translated into English by Eva Eichhorn. Many of the papers were retyped at the Department of Astronomy of the University of Florida.
