By this statement, the position seems to have remained 
nearly constant, but the distance to have undergone an evi- 
dent increase. The observation of 1781, as given in the 
Catalogue of 1782, states the angle at 40° 58' np , which is a 
mistake of computation or printing. It has misled M. Struve 
into the conclusion df a binary system and elliptic orbit.
