The measures of 1783.48, recorded in the Catalogue of 
1785, give 
Position 55 0 9' nf ; Distance 15".25. 
The angle therefore seems liable to no alteration, but the 
distance is increased if the measure of 1783 be correct; but it 
is only the result of a single measure. 
This star is remarkable for the great differences between 
the means of several independent sets of measures, while the 
star presents no peculiar difficulty. One of the angles differs 
3° 23' from the mean of all ; and this may be considered the 
maximum error to which the measure of an angle can be 
considered liable, unless in peculiar cases.
