Table II is a list complete for the first two hours of 1\.A.. 

 and coni])lete to magnitude 5.3 for the remainder, of all stars 

 given in Bnrnham's General Catalogue for which the ty])e of 

 spectrum is given in Harvard Annals, Vol. LVI, No. 7 (Spectra 

 of 745 Doubles by Annie J. Cannon), for which the apparent 

 distance is under i" .2. Stars appearing in Table I are excluded. 



TABLE II. 



: Signifies angular motion doubtful but very small. 



It is to be expected that the knowledge of double stars will 

 aid in solving the problems of the stellar system. If we could 

 look at the Sun from a distance re])resented by a parallax of i", 

 we should see the Earth revolving arotmd it at a mean distance
