This star to night admirably defined ; the measures were 
gotten with a power of 133, with the greatest facility. 
Mean result. 
Position 84° 24 / sf Distance 5". 528. Epoch 1822.67. 
The observations of March 19, 1821, are rejected in taking 
the mean. 
Other measures of this star are,

With regard to the angle, a slight change may still be sus- 
pected, but the diminution of distance is not to be doubted, 
even should the rejected observations of March 19, be the 
true ones.

The measures of Sir W. Herschel are, 288.24 
Position 8 1° 14' np. Distance 1' 3 i".86 ; 1781.83. 
The angle of position appears to have increased, as an error 
of 4 0 could hardly be committed in the measure of so distant 
a star.
