The night is remarkably fine. Observations made on the meridian.

Measures of distance I cannot obtain, yet the night is fine, and the stars are only 

 15 minutes west of the meridian.

Observed on the meridian with 157 ; with 181 I cannot see the small star. 



• Mean Result. 

 Position 22*' 47' sf (15 Obs.) ; Epoch 1825.15 ; 

 Distance 3o".536 (loObs. ) ; Epoch 1825.27. 



The measures of 1783 are. Position 19° 54' sf; Distance 

 35".62. The difference of Position 2° 53' is not material, con- 

 sidering the difficulty of the star ; but a diminution of distance 

 to the extent of 5".i deserves notice, because the microme- 

 trical error of the earlier observations would tend to produce 

 an apparent increase. (H.)
