174 -^ Cdurfe of Experiments 



I put it by itfelf in a Glafs of frerti Wa- 

 ter, and looked at it frequently, but faw no

The Head-Part feiz d a Piece of Worm^ 

 and in about a Week produced a new Body 

 with the Right-Side out, as in other Polypes. 



Though I made feveral Trials before and 

 fince, I could never fucceed in turning Pc?- 

 lypes^ fo well as in the above Experiment: 

 which I impute to my Want of the Means 

 Mr, Trembley ufes, as well as the Dex- 

 terity whereof he is Mafter : whofe Account 

 of his having turned many, and their livings 

 thriving, and producing young Ones in that 

 inverted State, I don't in the leafl doubt the 

 Truth of. And when that Gentleman pleafes 

 to publifh his own Method, which I (hould 

 think myfelf unworthy of knowing if 1 

 endeavoured to take any of the Honour of 

 it from him, moft reafonable People, I be-* 

 lieve, will be convinced. 



Notwithftanding, this Operation will al- 

 ways be attended with great Difficulty: and 

 none muft exped: to fucceed in it, but thofe 

 who have much Patience, Care, and Dex- 

 terity J and have, moreover, been exercifed 

 in the niceft manual Experiments.
