In the former Paper the attention of astronomers was par- 
ticularly directed to this star, on account of a considerable 
proper motion which it was supposed to have, in common 
with a very distant star 30 Scorpii ; and as the point is a very 
interesting one, the preceding observations were made, with 
a view of placing the matter beyond doubt : a few comments 
upon them will perhaps be not without their use.

In the above diagram, the close stars of A B of 36 Ophiuchi 
are represented relatively to the star C, to 30 Scorpii, and 
to A B of 38 Ophiuchi, as seen in the telescope ; C preceding 
A of 36 to the north, and A of 38 following it to the south. 
First, as it regards Declination. 
If any proper motion of 36 exist in this direction, (supposing 
the star C at rest) the effect of it will be to increase, or diminish
