NOTE 
ON THE FACULTY OF REPEATED RE-VIVIFICATION POSSESSED BT 
THE ROTIFER A, 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 moisttire 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 of 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.
