358 Mr. Herschel’s and Mr. South’s observations of the apparent 
y Herculis continued. 
May 20, 1821. 
The small star will bear no illumination in the five-feet 
equatorial, the measures are only approximate. 
Position = 23°+ sp 
Distance = S9"-5 ± 
May 28, 1822. 
The small star bears so extremely feeble an illumination, 
that to procure measures is excessively difficult ; indeed it 
cannot be seen unless the eye is directed to another part of 
the field. 4 and 15 magnitudes.

Position 2 6° 14' sp ; Distance 38". 325 ; Epoch 1821.85. 
Other measures are, 
1782.82; Pos. 21 0 o' sp ; Dist. 39".45 ; H. Cat. of 1782 and MS. each being a 
mean of two measures in 1782 and 1783. 
1819.64; Pos. 26 48 sp; Dist. 4o".8. Struve, Additam. 191. 
M. Struve suspects a change in the angle of position, but 
it is rather equivocal. The angle, 21 0 o’ sp, is a mean of 19 0 30' 
(the angle in the printed Catalogue) and 22 0 30', taken the 
following year.
