AEGELANDER'S STARS {continued). 



Note. — I omitted from Class III., Group I.," tlie star C. A., No. 167, which 



r 

 properly belongs in Class II., Group II., and would there change —~— to 0.762. 



The values of this quantity were computed with two decimals in sin- x '^^^ sin x 

 as {f — ^), and are not always sure to the third. 



The stare investigated by Lundalil show less accordance. There 

 are more of the stars with small proper motions (0".12 — 0".09), which 

 appear to move not in accordance with the hyi^othesis of solar motion : 

 I attribute this, in part at least, to the errors in Pond's and Bradley's 

 observations, which, for this series, are less perfectly eliminated thaa 

 for Argelander's.
