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 0 in its appa- 
rent orbit, it seems actually to have receded nearly 50'. 
Further observations must elucidate this difficulty. (H.)
