This star precedes 11 («) Ophiuchi by 12' (of space) and is 
4' to the south of it, according to the place of the latter star, 
brought up from Bode’s Catalogue. The right ascension and 
declination here set down, are those determined at the time 
of observation, neglecting the corrections for aberration, &c. 
There is no doubt therefore of its identity with the star II. 23, 
which is stated in the MS. Obs. of May, 1782, to be “ a small 
star just preceding the nth of Serpentarius,” though the 
measures agree very ill. They may be stated as follows : 
1782.38 ; Position 46° 24' np ; H. Catalogue of 1782. 
1802.39 ; 66 56 np ; H. Account of Changes, &c. 
1823.27 ; 51 7 np ; H. and S. ut supra. 
Future obsvrvations must determine which of these mea- 
sures is in error, but unless two out of the three are very far 
from the truth, there must have been a material change in 
the position.
