(Note) 12 Lyncis. The change of relative position in the three stars is conformable to the idea of a rotation of the 
two closer ones (A, B) about their common centre of gravity, the distant one (C) remaining at rest. Although the 
present data are very imperfect, we may yet compute the masses which satisfy the conditions, by the formula 
A - An g u l^ VeL ofB v x Cos $ Mean Pos. (sf) of B - Mean Pos. (np) of C } 
T ~ Angular Vel. of C X Dist. of C X ^ OS - * W ' •> 
= 5574 x x Cos. (45 0 20') = 0.9503, or nearly a ratio of equality. 
1086 9849 
The apparent magnitudes also are nearly equal ; and though it is true the inequality lies the other way, yet it must 
be remembered that in results so obtained, even an approach to coincidence adds something to the degree of proba- 
bility. Further observations must decide on their real value.
