chiefly in the hottest months of summer ; and that they 

 breed not in champaign, but in bushes and hedges. 

 Whereby it may be conceived that the spirit of them 

 is very fine, and not to be refined but by summer 

 heats : and again, that by reason of the fineness it 

 doth easily exhale. In Italy, and the hotter coun

 other green of the fens, give as good shade as bushes. 

 It may be the glow-worms of the cold countries ripen 

 not so far as to be winged.

 that kind it is a motion of erection) ; and therefore 

 when a man would listen suddenly to any thing, he 

 starteth ; for the starting is an erection of the spirits
