Fig. 3 is * Herculis. It consists of a large and small star separated by a 

 space equal to twice the diameter of the larger. The smaller star is blue, an< 

 the larger white. This object is situated in the head of the constellation Her 

 cules, about thirty degrees southwest of the conspicuous star Lyra, and six 

 degrees northwest of Ras Alhague, a star of nearly equal magnitude. 



Fig. 4 is a view of y Andro?nedcB : the small star is of a fine greenish-blue 

 color, separate from the large star about nine seconds, or four diameters of that 

 star ; the larger star is of a reddish- white. It is situated in the left foot of 

 Andromeda, and is distinguished by the name of Almaach. It is a star of the 

 second magnitude, about forty-two degrees of north declination. It is about 

 twelve degrees nearly due west from the variable star Algol. 



Fig 5 is Cygni : the smaller star is blue, and they are separated about ten 

 diameters. This star is situated in the eastern wing of the Swan ; right as- 

 cension, 2 Ih. 4m, north declination twenty-eight degrees, and is about twenty 

 degrees southeast of Denib, the principal star of this constellation. 



Fig. 6 represents Aquarii. The two stars are nearly equal in apparent 

 magnitude, and one diameter and a half separate from each other ; both stars 

 are of a whitish color. It is in the middle of other three stars, which together 

 form a figure resembling the letter Y. Its right ascension is 22h.20m,and its 

 south declination about two degrees. It is a star of about the third magnitude. 



Fig. 7 represents the Pole-star. The accompanying star is a very faint 

 point, and requires an accurate telescope with considerable power to distin-
