This star is erroneously called VI. 26, in Struve’s Cata» 
logue, the latter being the same with e Sagittas. Neither is 
it IV. 2 6, as in South’s. A note of uncertainty is affixed to 
the designation of Flamsteed’s number in the Catalogue of 
1782, and the star there described is not the star whose place 
and measures are here set down.

This star appears to have undergone a great change both 
in angle and distance. Sir W. Herschel, by the measure of 
Jan. 23, 1783, made the position 32°.9' nf, and the interval 
only i\ diameter of the large star, which can hardly ( for 
stars of this magnitude) exceed 4" distance from centre to 
centre. The angle described in 39.06 years is qo°.oj, giv- 
ing an annual angular motion of — o°.5i4, being in the 
direction np sf or retrograde.
