LESSON X. 



ON GEORGIUM SIDVS, OR HERSCHEL. 



Muthesis with uplifted eye, 



Tracing the wonders of the sky, 



Now shews the mariner to guide 



His vessel through the Irackless tide} 



Now gazing on the blue profound, 



Where whirl the stars in endless round, 



Beholds new constellations rise, 



New systems crown the argent skies ; 



Views with new lustre round the glowing pole, 



Wide his stupendous orb the Georgian planet roll. 



PYE. 



1-T was for ages supposed that there were only 

 six planets in the solar system: and the ingenious 

 Kepler, a very eminent astronomer, was so firmly 

 persuaded there were no more, that he confesses, 

 one of the three things which he anxiously sought 

 to find the reason of, was, why the planets were 

 six in number ? 



It is to the indefatigable application of an astro- 

 nomer, who has long resided in this country (and 

 whom I have had frequent occasion to mention), 

 Dr. William Hersshel, that we are indebted, 

 amongst other; brilliant discoveries, for that of a 

 planet, which is the fourth of the superior ones, 

 and the farthest from the sun of any yet disco- 

 vered.
