ABSTRACT
Even authors in the 19th century had occasionally a few ‘geographical’problems: the locality Garschenthal (Uvaly, 8 km SE Mikulov) was mentioned by Reuss (1874) as situated in Styria and in Hungary; the latter opinion had been shared also by Manzoni (1878). Such mistakes can probably easily be explained by the fact, that these authors got their material from local collectors, whose names are frequently mentioned in their publications. This is also similar for material from Moravia studied by Reuss (1847); he mentions in this connection three names: Mr Poppelack (an architect from Feldsberg Valtice, Moravia), Dr J. Eitlberger from Brünn ( Brno, Moravia) and Mr Rubesch, curator of the mineralogical collections at Bilin ( Bílina, Bohemia, Czech Republic).
