«« the fame Degree of Latitude on the Elliptical and on 
“ the Circular Meridian, is the fame in both Cafes, and 
“ in the fame Ratio as the abfolute Centrifugal Forces 
u reprefented by the Perpendiculars R N, V Zi^Art. IX.) 
« Therefore to know whether the Centrifugal Force 
Ct (whether abfolute or relative) of the Point R,upon the 
ct oblong Spheroid A DB E, be lefs or greater in refped 
“ to the Centrifugal Force under the common ^Equator 
44 DE, than the Centrifugal Force (whether abfolute or 
44 relative) of the correfpondent Point Vupon the Sphere ; , 
44 nothing more is requir’d than to fee which is the 
44 longed of the two Perpendiculars, namely, R N in 
“ the oblong Spheroid, or V Z in the Sphere j (ince 
44 thefe two Lines exprefs the Radii of the Circles of 
44 Revolution, and confequently the abfolute Quantity, 
u of the Centrifugal Forces. 
“ qthly and laftly, That the Ratio of the Centrifugal - 
44 Forces of two correfpondent Points upon the oblong 
44 Spheroid A D B E, and the infcrib’d Sphere DHE, to the 
44 Centrifugal Force of their ^Equators is the fame, fuppo- 
€t ling the Sphere of any other Bignefs j and that it has 
“ been determin’d here of the Diameter D E, only to 
44 render the Demonftration ealier, by giving the fame 
44 Confequent to the Antecedents R N and V Z. For 
41 if about the Center C and with the Radius Cd, the* 
44 Circle dhe be defcrib’d equal (for Example) to a 
“ Meridian of a Sphere of the fame Solidity as theob- 
* 4 long Spheroid ADBE^ and the Radius C V be pro- 
« duc’d till it meet the Circle dh at the Point u , and 
« uz be let fall perpendicular to the common Axis of 
< Revolution, and parallel to VZ: It is plain, that 
4 * we fhall always have V Z: DC :: uz: dC , or 
44 and confequently will have the 
<4 fame
