NAKED EYE DOUBLE STARS DISCOVERED 

 BY BURNHAM. 



"R. BURNHAM has been especially successful 

 in discovering t-wo new classes of double sta,rs — 

 namely, naked eye stars with close companions, 

 and naked eye stars with faint companions. 

 Both classes of stars form excellent, though 

 mostly very difficult, test objects, and a list of them will, 

 no doubt, be valued by readers of Knowledge who possess 

 instruments of good quality. The numbers on the left 

 hand are the numbers in Mr. Burnham's catalogues. 

 These will enable observers to verify their observations 

 when they have independently made their measures or 

 estimates of the position, angle and magnitude of the 

 companion. q^^^^ p^jj^s.
