 y Ononis is from Rigel. |3, the northern horn of the Bull, 

 is also called the foot of Auriga, it is of the second magnU 

 hide, and in the line drawn from a in the eastern shoulder 

 of Orion through f Tauri.'the southern horn. The ecliptic 

 passes between the two horns. 



Leo. The Lion may be recognised by the same stars a and )3 



in the great Bear, which serve to point out the polar star. 

 They arc distant about 45° north of the Lion, which forms 

 a large trapezium, in which there is a star of the first mag- 

 nitude called Regulus, or Cor Leouis ; it is in a line with 

 Rigid and Procyon, but at the distance of 37° from the lat-* 

 ter. $ also, a star of the second magnitude in the Lion's 

 tail, i6 a little on the south of a line drawn from Arcturus 

 to Regulus : it is 24* to the east of Regulus, and makes an 

 equilateral triangle with Spica Virginia and Arcturus. 



Cancer is a constellation of small stars, which are distin-

way between the centre of Gemini and the Cor Leonis, or 



iu the line which joins Procyon and the tail of the great" 



Bear. From u the middle star of the belt of Orion, there 



proceeds a train, which is called the Sword ; it contains the 



Nebula. Aline drawn through the Sword and the star « 



points towards {, the southern horn of the Bull, and beyond 



it to the middle of Auriga. 



Auriga forms an irregular pentagon, the most northern 

 star of which is Capella : it is of the first magnitude, and 

 may be found by drawing a line through £ and a, the two 

 most northern stars in the body of the great Bear. 



Aries, the first of the twelve constellations in the Zodiac, 

 consists principally of two stars of the first magnitude, si- 

 tuated near one another: & the more western of the two, 

 is accompanied by y, of the 4th magnitude, which has been 

 called the first star in Aries, because it was once the nearest 

 star to the equinoctial point. This constellation is in the 

 same line with Aldebaran and Procyon, from the former of 

 which it is distant about 35°.

is of the second magnitude. They form a curve with its
