Beschreibung:
Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. The constellation boundaries are somewhat darker than I would have had them if I had not had to con sider the requirements of beginners. It seems to me very necessary that the extent of each constellation should be recognisable at a glance (at least by most of those who will use these maps). Indeed, if no other means would suffice for this, the spaces should be coloured as in geographical maps. I think the pre sent arrangement meets all requirements.
