 the celebrated Herfchel, and his ftellar dif- 

 coveries, is made in the form of a fimile, 

 and is therefore unexceptionable ; and it 

 p'affes on to the following charming apof- 

 trophe to the Stars. 



Roll on, ye Stars ! exult in youthful prime, 



Mark, with bright curves, the printlefs fteps of Time! 



Near, and more near, your beamy cars approach, 



And lefiening orbs on lefiening orbs incroach. 



Flowers of the Iky ! ye too to age muft yield, 



Frail as your filken filters of the field j 



Star after {tar from heavn's high arch lhall rufh, 



Suns (ink on funs, on fyftems fyftems rufti^ 



Headlong, extin6t, to one dark centre fall, 



And Death, and Night, and Chaos cover all 5 



Till o'er the wreck, emerging from the ftorm, 



Immortal nature lifts her changeful form; 



Mounts from the funeral pyre on wings of flame, 



And foars, and fhines, another and the fame.
