the stars be variable in magnitude, it is not easy to reconcile 
the observations, which are as follows ; — 
1781.62. Position 29 0 54' nf. H. Catalogue of 1782. “ Considerably unequal.” 
1787.36. MS. — 20 feet sweep . — “ 1st. class. Equal.” 
1802.25. 2 7 1 S P MS. 
1803.19. The position is not sp, as marked in the last observation, but nf— -7 feet.

1821.33. 40° 53' sp. H. and S. ut supra. The two last observations go to 
destroy M. Struve’s idea of several revolutions 
having been performed in 38 years.
