Epoch 1825.41. 
The change in this star since the last observations is such 
as to confirm the direction of its motion ; but the quantity is 
more than calculation would give, amounting to no less than 
6° 13', instead of i° 6'. This renders it probable that the 
measures of 1823 are erroneous,* and that Mr. Struve’s 
measure in 1820 (46° 33' np) is entitled to greater confi- 
dence. The former rest on the observations of one night ; 
and long experience has now shown, that this can never be 
fully depended on. (H.)

Position = 12° 1 8' nf J 5 Obs. | Diff. == 6° 10'. Extremely difficult. 
The small star only seen by glimpses. In the accuracy of the results I have no 
confidence. Observations of distance impracticable. 
* On referring to our original manuscripts, this suggestion offered by Mr. 
Herschel is corroborated ; for on the 19th June, 1822, the star was measured by 
one of us, in the absence of the other, and under very favourable circumstances, 
the mean of eight measures (the extremes of which differed only i° 22') gave. 
Position 45 0 33' np. As however the observations subsequently made, were so 
much at variance with them, it was thought advisable to give the preference to our 
joint result, and to suppress the other. Sloane-street, March 11, 1826.
