The measures of Sir William Herschel, recorded in his 
first Catalogue, show that this star has undergone no material 
change in angle, but perhaps a very slight increase of dis- 
tance. They are 
Position (1781.91) 88° 10' np ; Distance (1780.78) 52^.968. 
* The angle given in the printed Catalogue (6o° 55') is erroneously reduced.
