 The earlier measures of this star compared with the pre- 

 sent offer a discordance. In 1783 the position was stated at 

 ^'^24' 7z'/> ; in 1804, by a mean of two measures agreeing 

 well, 20° 34' np. It is therefore probable that the first mea- 

 sure might be in error, which from the extreme closeness of 

 the stars might well happen. It should be re-examined some 

 years hence. (H.)
