Mean Result. 
Position 21 0 39 ' sp (17 Obs.) ; Distance 2".970 (15 Obs.) ; 
Epoch 1825.03. 
The position at the Epoch 1782.86 was 36° 24' sp. A 
change therefore of 14° 45 7 has taken place in the angle 
of this star, being -{- o°.35o per annum, direct, or in the 
direction sp nf. This is too large a quantity to be attri- 
buted to error of observation, and the star therefore in all 
probability belongs to the class of binary systems, and should 
be carefully watched. (H.)
