£ Bootis ; I. 1 ; H. andS. 185. 



Double ; 2nd and 9th magnitudes.

Position = 55** 25' np \ 5 Obs. | DifF. = 2** 45'. Very satisfactory. 



Observations made by strong twilight, without artificial illumination of the wires. 

 The evening remarkably favourable j stars extremely steady, and distant from ths 

 meridian 20 minutes.

Observations of distance impracticable, on account of the unsteadiness of the stars.

Stars admirably defined. I never observed this difficult double star under more 

 favourable circumstances : the results are entitled to very considerable confidence : 

 the observations were procured when the star was a few minutes on either side of 

 the meridian.
