HOW TO OBSERVE THE HEAVENS. 



Fig. 7 



On the 2d September, the star Fomalhaut (first magnitude), passes the me- 

 ridian at midnight. This star being situate 30 south of the celestial equator, 

 is unfavorably situate for observation in northern latitudes. At New York its 

 greatest altitude is 20. There are three conspicuous stars of the second mag- 

 nitude in the constellation of Pegasus, two of which, Markab and Scheat, are 

 on the meridian at the same time with Fomalhaut, and the third *, about an 

 hour and a quarter before. 



In the annexed diagram, fig. 8, the most conspicuous stars which appears 

 during the night in August, September, and October, arc represented. The 

 stars marked 1, are in the constellation Pegasus. The stars 1| ff 1, and el, 

 are of the second magnitude, the last being a double star. The star 1, is of 

 the third magnitude, as also is the star a 2, which is on the right shoulder of 

 Aquarius. The star <* 1, and & 1, are also called MARKAB, and SCHEAT. These 

 are on the meridian together, and are separated by about 12.
