The True Theory of the Tides, ex- 

 tra&ed from that admired Trea- 

 tife of Mr. Ifaac Newton, Inti- 

 tled, Philofophiae Naturalis 

 Principia Mathematica ; Being 



x a Difcourfe prefented with that 

 Book to the late King James, by 

 Mr. Edmund Halley. 



IT may, perhaps, feem ftrange, that this Papery 

 being no other than a particular Account of a Boof^ 

 long fine e publifhed, Jhould now appear here, hut the 

 Defires of fever al honourable Perfons, which could not 

 be withflood, have obliged us to infer t it here, for the 

 f a k e °f Jucb 9 xv ho being lefs knowing in Mathematical 

 Matters, and therefore not daring to adventure on 

 the Author himfe If, arc notwithstanding, very curious 

 to be inform d of the Caufes of Things ; particularly 

 °f f° general and extraordinary Phenomena, as 

 are thofe of the Tides. Now this Paper having been 

 drawn up for the late Kjng James'* Vfe, (in whofe 

 t\ei?n the Bool^ was publifhed) and having given good 

 Satisfaction to thofe that got Copies of it j it is hop* 

 ed the Savans of the higher Form will indulge us 

 this Liberty we take to gratifie their Infer icurs in 

 point of Science j and not be offended, that we here 

 infifl more largely upon Mr. Newton'* Theory of 

 the Tides, which, how plai?i and eafie foever we 

 find, is very little under flood by the common P^ea-
