CANTO iv. OF GOOD AND EVIL. 145 



But when young Beauty on the realms above 

 Bends her bright eye, and trills the tones of love; 180 

 Seraphic sounds enchant this nether sphere; 

 And listening angels lean from Heaven to hear. 







" Next by SENSATION led, new joys commence 

 From the fine movements of the excited sense; 

 In swarms ideal urge their airy flight, 

 Adorn the day-scenes, and illume the night. 

 Her spells o'er all the hand of Fancy flings, 

 Gives form and substance to unreal things; 



tities of action, when there exists any accumulation of sensorial 

 power. 2. When the auditory nerve is exerted in such successive 

 actions as relieve each other, like stretching or yawning, as described 

 in Botanic Garden, Vol. II, Interlude the third, these successions of 

 sound are termed melody, and their combinations harmony. 3. From 

 the repetition of sounds at certain intervals of time ; as we hear them 

 with greater facility and accuracy, when we expect them ; because 

 they are then excited by volition, as well as by irritation, or at least 

 the tympanum is then better adapted to assist their production ; hence 

 the two musical times or bars; and hence the rhimes in poetry give 

 pleasure, as well as the measure of the verse : and lastly the pleasure 

 we receive from music, arises from the associations of agreeable sen- 

 timents with certain proportions, or repetitions, or quantities, or 

 times of sounds which have been previously acquired ; as explained 

 in Zoonomia Vol. I. Sect. XVI. 10. and Sect. XXII. 2.
