Sir Ifaac Newton has demonftrated (k) That 

 the Force of the Sun to move the Sea, is to the 

 Force of Gravity, as 1 to 11868100. Let 

 that be

And that the Force of the Moon to raife the 

 Sea is to Gravity, as 1 to 103 181 1. Let this 

 be 



G 



L. G : : i s. Hence, L = —% 



And fmce the Centrifugal force of the Parts 

 of the Earth arifing from its Diurnal Motion is 

 to Gravity, as I to 191. Let this be

The fame Philofopher has taught us (*) that 

 the Centrifugal force raues the Water at the 

 Equator above the Water at the Poles, to the 

 height of 85-100 Feet, Wherefore if that Force 

 which is as 6031, raife the Ocean to 85:100 

 Feet, the United forces of the Sun and Moon, 

 which are as I. will raife the fame to 14 Feet,
