Measures extremely difficult, on account of light clouds : the angles were gotten 
when the stars were on the meridian; but no observations of distance could be pro- 
cured till they were 40 minutes west of it.

.The difficulty of the measures of this star is no doubt the 
reason of the disagreement between the result (69° 36' np) of 
the observations of 1823, and the present. The discordance 
however is unfortunately such as to prevent any certain 
conclusion as to the motion or rest of the stars from being 
drawn. (H.)
