17 1 h wou ^ not Iiave alledg’d, that the late Motif . 
Caflini obferv'd Jupiter to be oval, as a Proof of young 
Monf. CaJJini's Hypothecs ; becaufe Jupiter is oval 
the other Way, that is, an oblate Spheroid flatted atthe 
Poles, as the faid late Monf. QaJJini gave the Propor- 
tion of the Axis, to the /Equatorial Diameter, to be as 
15 to 16.— * And our late ingenious Aftronomer, 
the Reverend Mr. Bound . , with a Telefcope of 123 Foot 
Focus, and ail excellent Micrometer, has given thofe 
Proportions as 11 to 12. If a Proof is to be drawn 
from Analogy, or what is obferv’d in other Planets, this 
• mufl: deftroy Monf. CaJJini's Hypothefis, and confirm 
Sir Ifaac Newton's. 
The Opinion of Dr. Burnet (the Thcorifl) quoted in 
the Memoirs, for the Year 1713, is but a very weak 
Argument in favour of Monf. CaJJini's Hypothefis, on 
Account of the Reafon Dr. Burnet give, to prove the 
Earth higher at the Poles, than the /Equator ; for he 
fays, “ That the Velocity of the Parts of the Earth, 
<c in its Diurnal Rotation, being greater at the /Equa- 
“ tor than towards the Poles, all the Water mufl be 
JC driven towards the /Equatorial Regions- from 
“ whence, being repelled by the Refiftance of the 
“ Air, it mufl: run off again towards the Poles * and 
“ fo the Figure of the Water was lengthen’d out into an 
“ oblong Spheroid, and confequently the Cruft of the 
« Earth over it did put on the fame Figure, &c. 
But why the Air ftiou’d reflft more towards the 
/Equator than the Poles, the Dodor did not give any 
Reafon to fliew *, and, if it had been fo,the fame Force, 
that drove the Water towards the /Equator, mufl: have 
kept it there. The Dodor, in the latter Part of his Af- 
fertion, forgot what he had faid in the former • for the 
Water cou’d not run off towards the Poles, whilft the 
Earth continued its Rotation with the fame Velocity.
