Earth came to be a Sphere ; nay, and it muft have ri- 
fen at the Equator and how much, 1 have already 
{hewn in my former Paper. 
Again, 1 f we fuppofe the Earth of an heterogeneous 
Fluid, before the diurnal Revolution, the heavieft Parts 
wou’d go towards the Center, and the lighter towards 
the Surface-, and that Way the Terraqueous Globe 
wou’d alfo become a Sphere, Then if, when the Cen- 
tral Parts are fix’d, and the fuperficial Strata are lull 
fluid, the Earth receives a diurnal Motion ; it will rife 
at the Equatorial Parts, and that to a greater Height 
than what I have (hewn in my former Paper, where I 
fuppos’d the Earth of uniform Matter. And that fome- 
thing like this muft be the Cafe,_ appears from what 
Sir Ifaac Newton has faid upon this Subjeft. For after 
having (hewn, from fuppofing the Earth of uniform Mat- 
ter that the Centrifugal Force of all its Parts won d 
bring it to be i 7 i Engtijb Miles higher at die Equator 
than at the Poles, and after having given i a Table of the 
proportionable Decreafe of the Length of the Degrees o 
a Meridian of the Earth, going from the Poles to the 
Equator in fuch a Figure of the Earth, with the 
Lengths that Pendulums muft have to fwing Seconds 
“n feveral Latitudes :,from a Comparifon of the Lengths 
of Pendulums (obferv’d by different Perfons to be flaorter 
towards the Equator, than in greater Latitudes (when 
they fwing Seconds) he (hews that the Earth muft be 
,■1-2 Miles higher at the Equator man at the Pol , 
and therefore that it muft be denfer towards the Central 
thanthe Superficial Parts to produce a flatted Spheroid, 
where the Equatorial Diameter mutt exceed the Axis lo 
much more ^ that ts, be longer fomething more than 
TIT Laftl'v let us fuppofe the Earth, at its firft Creation, 
t0 iVaTe been made o^Land and Water, the hrft as fol.d.
