« The measures are difficult, but the stars are extremely 
steady and well defined. Should the measures with the five- 
feet differ, these are to be preferred.”

Night very favorable. R’s observations taken when the stars 
were within 15 minutes east and west of the meridian ; S’s 
about half an hour after Mr. Richardson’s were completed.

Position 44 0 32' np ; Distance 8".8i8 ; Epoch 1823.69. 
Other measures are, 
1781.88 ; Position 34° 10' np ; Distance 8"„83, inaccurate. H. Catal. of 1782. Cor- 
rected by reference to MS. the distance being wrong cast up. 
The position is stated to be liable to considerable error on ac- 
count of obscurity.

1819.74; 39 32 np; Struve, Dorp. ii. Observationes 98, 102, 129. The dis- 
crepancy between this result and that of our measures is very extraordinary ; 
and is the more to be lamented as these stars form, perhaps, a binary system.
