Should this set favour one series of the former observations more than the other, 

 I feel so little confidence in them whilst obtaining them, that I would not reject 

 either, but would prefer receiving the mean of all, as a final determination. Night 

 tolerably clear, and the stars very steady.

Until arranging the work for presentation to the Royal 

 Society, I was not aware that the former memoir contained 

 the following observations of this double star, made by 

 Mr. Herschel and myself. Position io<* 6' nf; Distance
