These measures compared with those of 1783 give a 
change of — 3 0 51' in angle and + o".3 in distance for the 
nearer star B, and — ■ 4°54 / and -j- o".77 for the more distant 
one C. If these changes arise from real motions, and be not 
merely errors of observation, they cannot be accounted for 
by supposing the stars B and C at rest, and the central star 
A only in motion. ( H. )
