NOTE 



ON THE FACULTY OF REPEATED EE-VIVIFICATION POSSESSED BY 

 THE EOTIFERA, ETC. 



The Rotifer, a singular creature, although it can only 

 truly live in water, inhabits the moss on house-tops, dying 

 each time the sun dries up its place of retreat, to revive as 

 often as a shower of rain supplies it with the moisture essential 

 to its existence ; thus employing several years to exhaust the 

 eighteen days of life which nature has allotted to it. These 

 creatures were discovered by Leuwenhoeck, and have become 

 the types df a class already numerous, which undergo the 

 same conditions of life, and possess the same faculty. Besides 

 the Rotifera, the Tardigrades, (which belong to the Acari^) 

 and certain paste- eels, all exhibit a similar phenomenon.
