Proceedings of the Boyal Society of Edinburgh. [Sess. 
4. Inspection of the above table shows very clearly the preference in the 
apparent motions of the stars for the directions of the two apices A and B, 
and the extent to which they diverge from these directions. For example, 
Nos. 1-6, which are all at a considerable distance from A (95°, 79°, etc.), 
are all moving in directions not far from the direction of A, and in 
directions far from that of B. Nos. 20, 22, 36, etc., are similarly moving 
approximately towards B. Nos. 9 and 66 do not fall in either stream. 
No. 23 is taken as belonging to the second stream (moving towards B), 
as its distance from A is only 11°. There are a number of doubtful cases, 
such as No. 27. In the first instance doubtful cases were omitted, and the 
following tables formed giving the numbers, at various distances from the 
two apices A and B belonging to the two streams, which diverged 0°-10°, 
10° -20°, etc., from the directions of the two streams.
