The small star is light blue. Observed on the meridian. A small portion of

A cloudless sky; but the stars are extremely unsteady and ill defined; added to 
these circumstances, a small portion of the object-glass (perhaps one-eighth) is 
rendered useless by the unfortunate situation of the timbers of the observatory. 
The observations of position agree well enough ; but it is 
otherwise with those of distance. The night of August the 
20th was much more favourable than either of the nights on 
which the star was subsequently measured ; and as the mean 
of the distances procured on those nights will differ but little 
with that obtained on the 20th, if we take the three sets we 
shall probably not err much when we give as the 
Mean Result.

There appears not the least change of position in these

what it was in 1783. (HO
