 torment it in fuch a Manner as one cannot

 Bodies, eat off their Arms, and devour them 

 by little and little; which, I believe, has 

 been the Fate of many that were thought to 

 have been diffolved. 



The Figure and farther Defcription of 

 thefe Lice may be feen in the third of the 

 following Experiments. 



My Polypes were kept, at firft, in fmall 

 Glafs VefTels, containing about two Ounces 

 of Water each, with Mouths very near as 

 wide as their whole Diameter. Such Glafles 

 hold five or fix of them very conveniently, 

 admit their being put in or taken out with- 

 out Danger of Injury, and are eafily clean'd 

 and replenifli'd with frefli Water. But when 

 the Creatures multiplied, by Cutting and 

 other wife, to feveral Hundreds, I procured 

 fome larger GlaflTes, of nearly the fame Form, 

 containing better than three Quarts of Wa- 

 ter, and capable of holding an hundred and 

 fiifty or two hundred Polypes. In a Glafs of 

 this Size the Water need not be renewed fo 

 frequently, efpecially if the Faces be taken 

 out from time to time with the feathered
