 the young Ones proceeding from it, under 

 thefe Difadvantages, thrive as faft, and feem 

 as vigorous as thofe produced by perfect and 

 uncut Polypes. 



Some Care and Method is requifite in all 

 Experiments to make them fucceed well : 

 and whofoever would fee the wonderful Re- 

 ftoration of thefe Creatures, muft provide 

 fliarp Sciffars, and have a fmall open VelTelj 

 filled with good River or Pond- Water, in 

 Readinefs to put the Parts into the Moment 

 they are cut afunder ; and that, efpecially, 

 when the Operation is performed on a Slip 

 of Paper, where they will otherwife quick-

Nothing after this is necefiary, but to 

 (hift their Water, clean their Veffel at due

 are not equally careful, or fortunate, in
