In Character, uncertain, owing to the paucity of observations yet made ; and 

 the new determination of the proper motion of A. 

 ^ The Elchies telescope picked up and observed a new star, C, which may be 

 useful in determining the proper motion of A or B, or both.

In Character^ uncertain at present. 



In Magnitude, A seems steady ; but B, both by the Guajara and the Elchies 

 observation, has decreased ; while C may be constant. 



In Position and Distance, the Elchies observations do not confirm the B. A. C. 

 proper motion test for A ; but then they are excessively rude and little trust- 

 worthy, and future observers of A should measure it carefully both from 

 B and C.
