Mot tons rf the Polype^ 193 



*^ and fearching for fomething in the Glafs 

 ** to meafure from, that I might be more 

 ^' certain of the Truth, I found a little Speck 

 " in the Bottom of the Glafs, even with that 

 Part below the Head of the Polype from 

 which the Arms rife. Keeping my Eye 

 *' fixt to the Speck and Polype, I plainly 

 " faw it thrufl itfelf forwards with a feem- 

 ^' ing Spring ; fo that the Speck in the Glafs 

 ^* was now even with the upper Part of 

 ^* the Tail : and, in a Second after that, the 

 " Polype thruft itfelf forwards in the fame 

 " Manner, and left theSpeck in the Glafs 

 '* about the twelfth Part of an Inch behind 



'' it. 



*' During all thefe Motions I could not 



perceive either the Arms or Body more 

 extended than when I firft put in the 



'* Worm, altho' I attended particularly to 



^^ that Circumftance. 



" 1 don't know whether you have found 

 " any of the Arms cut off, without any 

 ** Part of the Head or Body adhering, to 

 *^ be endued with the reftoring Quality 

 *' which the Body has : but I have tryed the 

 *^ Expcrimeni four Times j and altho' the 

 ** Arms cut off continue with Life, con- 

 " tra(fting and extending themfelves, and 

 *' waving about ; yet the fecond Day they 

 " have always diffolved, and appeared like 

 O " trant
