In Magnitude, variable through probably a fourth of the whole light. 



In Colour, slightly variable ; A, from white to greenish, and B from the same 

 to bluish. 



In Position slowly retrograding, and in Distance rather decreasing, and not 

 showing relatively the large B. A. C. proper motion of A ; therefore in Character 

 a slow binary ; but, as first pointed out, and much dwelt on by the late Captain 

 Jacob, suffering some large perturbations by an unknown dark body. These, 

 however, will not explain the characteristics of the reputed first-class observation 

 of 185572.
