The distance appears to have increased no less than (P.5J6 ; 
and in so distant a star an error of 2 0 could scarcely have 
been commited in the angles, so that the position must have 
sustained a slight alteration. 
M. Struve, Dorpat Obs. iii. makes the difference of decli- 
nations of the two stars i' 44".26 (1821.90). Our measures 
computed give 1' 45". 791 for the same difference, which 
agrees precisely with one of his single measures.
