 quadrilateri. 



Sept. 27. — Double. Nearly equal, the following 

 a little larger. Both w. Distance 11". 822, being a 

 mean of the measures taken in Sept. Oct. Nov. and 

 Dec. 1779- As I suspect a motion in one of these 

 stars, I thought it best not to join other observations 

 in that measure. Position 4° 9' n preceding.

 praecedens. 



Sept. 27. — Double. Very unequal. Lw; S d. 

 Distance 12". 503, a mean of the observations in

li. 1 Ononis, Fl. 44. Trium contiguarum in ense 

 austrina. 



Oct. 7. — Treble. It is the following or larger of 

 the 2 i's. One is L ; the other 2 are extremely small. 

 L w ; the other 2 both dusky r. Distance of the 

 nearest 12". 5. Distance of the farthest 48" 31'". 

 Position of the nearest 43° 5 1' following. Position of 

 the farthest 11° 19' s following. 



J In a future collection this will be found as a treble star of 

 the first class ; the large star having a small one preceding, easily 

 seen with 460 and 932.— Orig.

20. In constellatione Bootis. 



June 25. — Double. Draw a line through ir and £ 

 to die small star under the right foot, and erecting a

 the end of it will mark out this double star. Pretty
