DR. DARWIN. 183 



The recurrence of two equally accented 

 words three times in the ftanza, and twice 

 in the laft line, incumbers the verification, 

 while the fmgle ufe of the fpondee in the 

 preceding four lines, from Hope, gives it 

 grace and beauty. Dr. Darwin, in the 

 following paflage, has ufed it frequently, 

 without producing any fuch dead weight 

 upon the verfe. The quotation is from 

 the charge of the Botanic Queen to the 

 Nymphs of Fire, a poetic alleg6ry for the 

 influence of the fluid matter of heat in for- 

 warding the germination and growth of 

 plants. 



Pervade, pellucid forms, their cold retreat ! 

 Ray, from bright orbs, your viewlefs floods of heat ! 

 From earth's deep ivaftes electric torrents pour, 

 Or fhed from heav'n the fcintillating ihower! 

 Pierce the dull root ', relax its fibre trains, 

 Thaw the thick blood that lingers in its veins ! 

 Melt with 'warm breath, the fragrant gums that bind 

 Tk' expanding foliage in its fcaly rind 1
