In the common or vital air feems conducive to 

 health, yet when it becomes accumulated beyond 

 this falutary proportion, it may injure what it 

 was defigned to preferve (z)-, from which re- 

 flection the poet judicioufly refolves, 



• Now from the town 



Buried in fmoke, and fleep, and noifome damps, 

 Oft let me wander o'er the dewy fields, 

 Where frelhnefs breathes, and dam the trembling 

 drops 



From the bent bufh, as through the verdant maze 

 Of fweet-briar hedges I purfue my walk •> 

 Or tafte the fmell of dairy ; or afcend 



Some eminence, ■ 



And fee the country, far diffus'd around, 

 One boundlefs blufh, one white-empurpled (hower 

 Of mingled bloflbms ; where the raptur'd eye 

 Xlurries frpm joy to joy {a). 



Hence purer fpirits through the blood diffused, 

 Give to the lip its ruby-tinelured hue : 

 Hence Health's gay fmile illumes the dimpling 

 cheek ; 



And the pulfe lightly dances, as the breaft 

 Inhales, flow-heav'd, the pure refrefliing air (b)*
