8 Cl'IDE TO THE CONSTELLATIONS. 



Ophiucus and f 30 t the north-east of y, the line drawn from it \o y 

 points on the north to g Herculis, and on the south, or ra- 

 ther south-west, to a Serpentis, which forms nearly an equi- 

 lateral triangle with the head of Hercules and the Crown. 

 The line drawn from the head of Ophiucus to the southern 

 scale of the Balance passes through £ and g Ophiuci, two 

 stars of the third and fourth magnitudes, which are at the 

 distance of only 1° 20' from one another, and in the line 

 drawn perpendicular to that which was last described, o 

 lies to the north-west of g, and these two stars point on the 

 south-east towards f in the western knee of Ophiucus, which 

 is 7|° from g. This same direction will lead near to ^, the 

 star in the other knee of Ophiucus, which is about 9|° to 

 the south east of f. These same stars £ and g point a little 

 below cc Serpeutis, and, if considered as one group, they 

 would make nearly an equilateral triangle with a, Serpentis 

 and in the northern scale, 4§° north-west of <* Serpentis 

 is £, and 3° south-east is g of the same constellation. The 

 direction of these three stars is also towards I and g Ophi- 

 uci, which are 11° from g Serpentis. /3 and y, the two stars 

 in the eastern shoulder of Ophiucus, are in the line drawn 

 from the head of Hercules to the head of Sagittarius : this 

 line passes a little to the south-east of the head of Ophi- 

 ucus. # is 8° and y 11° from the head of Ophiucus. A 

 line drawn through them would pass between the two head* 

 of Hercules and Ophiucus: the line connecting these two 

 heads points to at the extremity of the tail of the Ser- 

 pent, which is 22° east of the head of Ophiucus. The 

 line drawn from the most eastern stars in the Crown (which 

 are on the side turned towards the Lyre) to a Serpentis 

 passes by the head of the Serpent, between y and 0, two 

 stars of the third magnitude : $ is the more western of 

 the two. The western foot of Ophiucus lies between An- 

 tares and /3, the northern star in the head of the Scorpion : 

 the eastern leg is between Antares and y, Sagittarii, which 

 is the highest and most western star in the how. 

 Capricorn. Capricorn may be found by producing the line drawn 



from the Lyve to the 'Eagle: this line will pass through a. 

 and £ two stars of the third magnitude in the head of Capri- 

 corn. These star* are only 2° from one another. Farther
