Neither star bears sufficient illumination, and the observations of distance maj- 

 perhaps be a little inaccurate.

The position in 1783 was 15" 48' nf, so that there is no 

 reason to suppose any change in this star, as there is so little 

 difference in their magnitudes, that the larger might easily 

 be mistaken for the smaller, and thus 180° difference in posi- 

 tion arise. (H.)
