On the 22nd January, 1783, the position of A C was 

 66^ 36' sp, differing — 4° 38' from the present angle. Ac- 

 cording to PiAzzi this star has a proper motion of — o".i4 

 per annum in R. A. amounting to nearly — 6" in 42 years. 

 If this be confined to the large star, an apparent relative 

 motion of the two stars should arise in the direction, and 

 nearly to the amount actually observed. (H.)
