Oxford Society. To this he adds quafuor Lemmata de novo^ 
V which he applies to the Explication of Carteftus his Syftero, 
fuppofing the matter between the Vortices that joyn to that 
of the Sun, to influence that by its Ingrefs, fo as to keep the 
Sun in the Focus of the ElUptick^ Vortex. This premifed, 
he fubjoins his firft Lemma, where he prefents the Sun in the 
Center of Gravity of its Syftem without Vortex or turbina- 
ted motion : in the fecond he direfts it to the Foetus of the 
EUlpfe : in the third he generates the Vortex by the conflift 
of the en t ring and contained matter, exaftly agreeing with 
the Phenomena s and turns round the Sun by the motion of 
the Vortex^ giving the Planets their exaft Motions, which 
they cannot deviate from. 
Laftly, He generates Earths or Planets by the Coalition 
of many fmaller into greater Bodies : thefe he explains more 
particularly from his Principles ^ and then anfwers two Ob- 
jeftions which may be made againft it (as he conceives,) and a 
third which a Demonftration of Mr.N^n?Ws,upon a Suppofi- 
tion of his, doth dire£i:ly oppofe: to which he anfwers. That 
that Hypothefis ought to be corrected 5 and gives hisRea- 
fons which he thinks fufficient. He difapproves of the Hy- 
pothefis of the Planets gravitating upon each other, and ex* 
plains his Reafons from the fimilitude of a Ship in the Wa- 
ter 5 and ends his Epiftle with this Conclufion, That though 
the Moon were a thoufand times bigger than the Earth, it 
would not be able to move the leaft Sand out of its place, if 
that were the Center of the Earth : the like he fuppofes of 
the other Planets, with refpeft to the Sun.
