E r r a t a. W, ~ 2 ~ 5 7 4 . This star is Lal. 44096 and Glasg. 5876. The Right ascension given in Weisse is about 20' too great W, 1 ~ 1 2 3 and 126. The differences between these two stars, measured on Jan. 1 2 , were z1?68 and 5'2010. The place of the second star given in Weisse requires a correction of -2' in declination. W, 1~183.

Ob ausserdem Weisse noch einen Druck- oder Red.- Fehler enthiilt, kann ich nicht entscheiden, da die hiesige Sternwarte den Weisse'schen Catalog nicht besitzt. Uebrigens hat der Stem nach C. H. F.
