geneous Fluid, which fhould turn about the Axis CB, 
would afiume the fame Form as that of our hetero- 
geneous Fluids. But if this Spheroid fhould then put 
on a fix'd State, except only fome Canal pqr, the 
Water in this Canal would be in z^Equilibrio ; for 
without this, the Spheroid could not be efteem'd as 
having arrived to its fix'd State. But this Supposition 
comes to the fame as that of our heterogeneous Sphe- 
roid, compofed of elliptical Beds, in which fhould 
be found a Canal pqr of a homogeneous Fluid > pro- 
vided that the Space, which this Canal poflefies in the 
Globe, be not of fo large an Extent, as to change the 
Law of Attra&ion. 
It might now be thought feafonable to give Ex- 
amples, for illuftrating the foregoing Theory 5 but 
they are fo eafy to be produced, aftet what is already 
done, that I fhall leave them to the inquifitive Reader, 
having perhaps exceeded the Limits, within which this 
Difcourfe fhould be confined. Therefore I fhall only 
add the few Obfervations following. 
The only three Planets, in which we can be affured 
of Gravitation, and the centrifugal Force, are the Sun, 
Jupiter, and the Earth. As to the Sun, the centri- 
fugal Force is there fo fmall, in refpeft of its Gravity, 
that his Poles muft be very little deprefs'd, fo that we 
cannot be fenfibleof it by Obfervation. Then as to 
Jupiter, Obfervations make him fomething lefs flat 
than according to Sir Jfaac Newton s that is to fay, 
than if he were compofed of Matter of an uniform 
Denfity. Therefore by the foregoing Theory, he 
muft be a little more denfe towards the Centre, than 
at the Parts near the Superficies. We might make a 
thoufand Hypothefes about the Manner of diftributing
