fame thing, with all the Judgment, Can- 

 dour, and Circumfpedion requifite in Cafes 

 of fuch a Nature -, freely inviting Gentlemen 

 to your Houfe, to examine for themfelves, 

 and make their own Eyes their Informers. 

 But, as every Body could not do this, you

 Manner, and laying before the Royal Society y

 Time would give you leave to make, which 

 you have fince permitted to be publifhed in 

 the Philofophical TrafifaBions^ for the In- 

 formation of all the World.

 me with three of your Polypes^ very foon

 put them to the fevereft Teft> and, to en- 

 courage and affift me in fo doing, have fre- 

 quently honoured me with your Company, 

 and been yourfelf a Witnefs of my Proceed- 

 ings. To You, therefore, I owe my Tefli- 

 mony of the Truth, as given in the following 

 Obfervations and Experiments, many of 

 which were made under your own Eye; 

 and, it is with great Pleafure, I feize this 

 Opportunity of acknowledging my Obligati- 

 ons to you for Abundance of other Civilities 

 and Favours. 



With thefe three Polype si began my E?:-
