 continued. 

 Either there is a considerable error in these or the mea- 

 sures of 1821, or the result is unfavourable to the motion 

 assigned to this star, as, instead of advancing 3° in its appa- 

 rent orbit, it seems actually to have receded nearly 50'. 

 Further observations must elucidate this difficulty. (H.)
