The small star observed on the 10th April will serve to 
verify the proper motion of A (3 6), which has been supposed 
in some way connected with the star 30 Scorpii, though at a 
great distance (12') from it, by reason of an observation of 
Bessel, that they have a common proper motion. The point 
is a very interesting one, especially should other stars in this 
neighbourhood appear to be similarly affected. But our 
knowledge of the proper motions of the stars is lamentably 
deficient — or rather our ignorance respecting them is the 
opprobrium of modern astronomy.
