by the accordant estimates of all, to two regions on opposite sides 
of the pole, and at about 60° declination, so that an abundant 
regions different from those which he had previously observed, 
and each one is now engaged in repeating his former work, with 
of the revision series. Thus I think we may believe that no 
star brighter than the 7th magnitude will escape notice, that the 
misidentifications will be few, and that the final results for the 
magnitudes deduced from so large a number of observations, free 
from systematic discordance, will be entitled to a high degree of 
confidence, : 
This revision, as well as the repetition of the original work, are 
both of them more than half completed, and I see no reason to feel 
otherwise than very well satisfied with the results. My great

Bessel called its magnitude 7, and Mr. Davis noted it as 6-1 in the 
beginning of 1871; but his subsequent observations have shown it 
to fluctuate between the limits 6‘2° and 7°3° in a period of about
