These corrections were obtained by subtracting each result from the mean 

 of all the results for each night, and then by combining the remainders according 

 to the weights of the determinations. They are to be applied, with the proper 

 sign, to the Right Ascension and Declination of the Planet ; the South Declina- 

 tion being, as usual, regarded as negative. On the night of November 9th, a mis- 

 take was made in reading the level attached to the declination circle in the instance 

 ofi Capricorni. In reducing the observations, what was, very probably, the read- 

 ing was used instead of that given in the observing book. An anomaly still, 

 however, appearing in the result ; it has been thought better wholly to reject the 

 observation of declination of this star for that night. The correction of decli- 

 nation for November 9th will consequently be + 0".9, instead of what would be 

 obtained from the Table given above ; or November, 9th 5 = — 13° 34' 11 ".4. 



Since the corrections given in the Table are mutual, any more accurate deter- 

 mination which may hereafter be obtained for one star will be applicable to all.
