J^iil in a Straight Line in ben the Vis Ccnirlpeta ccafes^ ivith 

 nvhat degree of Velocity is the Motion carried on ? — TheConfequencc 

 y of giving an innate Poiver to Body, both to bes^in and continue 

 jkich Motions^ is doivnright Matcrialijm. — A Confequence of the 

 FirJ} Latv of Motion^ that Body cannot go on in Vacuo, by Pref- 

 fure, but only by Impulfe. — The Motions of the Tides iinthout 

 ProjeBion or Gravitation ; aitd, if by a Vis Infita, that Vis ?nujl 

 begin the Motion. — The ijuhole Nevotonian Syftem depends upon the 

 frjl Laiv of Motion. — Of the Compoftion of the Planetary Mo- 

 tlon.—^n order to prove this^ the Nevutonians mufl prove one or o- 

 .ther of three Propofitions. — imo, That it is impofjible^ by the Na- 

 ture of thifigs, it could be ftmple. — This a Geometrical Problem^ 

 and^ if true^ capable of Demonfl ration. — If not demonf rated Geo- 

 inetrically^ it ought to be demonf rated Metaphyfcally. — Or, 2do, 

 They mufl prove that the fame Motion, if produced by different 

 Caufes, tvill not have the fame Properties, — Or, 3tio, They mu/l 

 prove that all the Bodies in our Solar Syflem gravitate toivards one 

 another, — The Proof from Analogy here altogether defcient, — No 

 Proof neither^ from Final Caufes, — The Defcent of the Playlet 

 ■ from the Tangent otherivife accounted for. — Of the Motion of the 

 Earth upon its Axis. — This explained in thefaine Way as the Mo- 

 tion of a Stone in a Sling. — If the Neivtonian Syflem is laid afide^ 

 then mine mufl take Place. — AJhort Abridgment of it. — No Reafon 

 for the Nevutonians maintaining fuch Paradoxes^ except to demons 

 fir ate the Laivs of the Planetary Motion. — This can be done ivith^ 

 out them by an eafy Analyfis. — Anfivers to the Objeclion againfl Dc" 

 monflration by Analyfis or Hypothefis. — If this aemonflration be good^ 

 then is the Neivtonian Syflem cleared of many difficulties and abfur- 

 dities. — 7/^6^6' reckoned up. — The Nevutonians ought to give up thefcy 

 or to defend them by more plaufble Arguments. — They ought to deal 

 more in Diflinciions than they have hitherto done. -^Examples of 

 /heir Defeil in this Rcfpe^l. — The Authority of Dr Clarke infup-
