SIR ISAAC NEWTON'S REFLECTING TELESCOPE. 



2. Sir William Potty's Double-bottomed boat. 



" Upon the reading of a letter, sent out of Ireland to the Secretary, con- 

 cerning the expectation, which the Committee, that heretofore had 

 given the Society an Account of S r "William Petty's new ship, did 

 entertain for hearing the sense of the Society thereupon, it was 



" Ordered, That the Committtee should be put in minde by the Secretary 

 that the Matter of Navigation, being a State-concerne, was not proper 

 to be managed by the Society ; And that S r "William Petty, for his 

 private satisfaction, may, when he pleases, have the sense (if he hath 

 it not already) of particular Members of the Society, concerning his 

 new Invention." Council Minutes, May 27, 1663. 



" The Papers of the next Philosophical Transactions, having been con- 

 sidered of, and the account therein given concerning the Structure 

 and Advantages of S r William Petty's Double-bottom'd ship ; it was 

 resolved, that the publication of them should be differed, till his 

 Ma'? had been made acquainted with the particulars therein, relating 

 to the said ship." Council Minutes, April 26, 1665.
