236 Mr. South' s observations of the apparent distances 



No. DCCXXIII. R. A. 19^ 36" ; Decl. lo' 21' N. 



StRUVE, 632 ; I. 91. 



Double ; 8t and 11th magnitudes. 



Passy ; July 18, 1825 ; Seven-feet Equatorial. 



The small star is decidedly light blue, and is rendered rather more distinct by 

 slight illumination ; under however sufficient to show the wires of the micrometer 

 pleasantly, it becomes invisible : the measures are excessively difficult, and some 

 degree of suspicion attaches to the results. Night remarkably clear, but the stars 

 are not steady.

Sir W. Herschel's measures are — 1783, Position 8° iS' np, 

 and 1802, 12° 23' np. These, discordant as they are with 

 the present measure and with each other, yet afford some- 

 what of a presumption of a very slow change of position in 

 the direction np s J or retrograde. ( H. )

The small star is light blue, and becomes more distinct by a slight illumination ; 

 yet the measures are so excessively difficult, that it will be useless to attempt ob- 

 serving it, except under the most favourable circumstances. The present is a night 

 peculiarly fine, and the stars are remarkably steady and well defined.
