278 Mr. South’s observations of tine apparent distances 
No. D CCLXXXII. R. A. 2i h 6 m ; Decl. 9° 17'N. 
8 Equulei ; Struve, 715 ; IV. 37. 
Double ; 5th and 15th, or 20th magnitudes ; I have often 
looked for the small star in England, but could never 
detect it. 
Passy ; October 2 , 1824 ; Seven-feet Equatorial. 
Z 452} Excessively difficult. 
The small star is so extremely faint, that it cannot be seen even in the unillu- 
minated field, without great attention. The observations were made with 105 ; and 
although the night is unusually favourable for delicate determinations, yet the 
measures here given must be received with some suspicion. 
Passy ; October 12 , 1825 ; Seven-feet Equatorial. 
5th and 15th, or 20th magnitudes. 
Z 1 Excessively difficult. 
Observed on the meridian with 157. Night very fine ; the accuracy of the results 
is perhaps questionable. 
Mean Result. 
Position 48° s' nf (15 Obs.); Distance 26".24o (12 Obs. ) ; 
Epoch 1825.26. 
This star appears to have sustained a very extraordinary 
change both in distance and position. Sir W. Herschel’s 
measures are as follows : — 1781.80 (Oct. 22)Pos. 11 0 39' nf, 
Dist. 19".533. Thus in 43-46 years no less an arc than 
— 36° 24' has been described, being at the rate of — o°.838 
per annum, and a change of distance to the amount of -j- 6". 7 07, 
or -f- o".i54 per annum. 
An observation in a 20-feet sweep in 1785 confirms the 
fact of the angle made by the two stars being then small.
