Position 23 0 42' sp ; Distance 9^.453 ; 1822.59.

measures. 
The angles agree very well ; but the distances are alto- 
gether unsatisfactory. The night of April 10, was one of 
rare occurrence for the steadiness and exact definition of 
the stars ; and the measure ld'.oo'j of that night, supported 
as it is by that of March 14, 1821, ought, not improbably, 
to be preferred, to the rejection of that of April 19, though 
nothing appears on the face of the observations to invalidate 
the latter.
