No. DCCXXVII. continued. 



Mean Result. 



Position 26° 42' w/ ; Distance 5". 58 7 ; Epoch 1825.14. 



The measures of 1783 and 1802 give 29° s' npy and 

 30*" q' np respectively for the angles of position. The esti- 

 mations in diameters of the distance correspond to about 5 or 

 6" central distance. This star therefore has not varied sen- 

 sibly. (H.)

Epoch 1825.23. 



This position differs only o° S7' from that of 1783. The 

 distances too present an exact correspondence, Sir W. Hers- 

 chel's measure being 10". 140. (H.)
