318 THE WATER-FLEA. 



this element is in early spring, when the ice of 

 winter is hardly dissolved, and the fluid only six or 

 seven degrees above freezing, yet they become im- 

 mediately sensible of this temperature, and are ex- 

 cited to animation and the vocations of their being.

 this beetle, conveying no meaning to our present comprehensions, 

 is a corruption of some syllable in former use. Its subterranean
