To leave nothing unexamin’d, relating to theContro- 
verfy, I have again conlider’d the Meafures and Obfer- 
vations, mentioned in the Account of the Meridian drawn 
thro’ France , in the Memoirs of the Royal Academy , 
for the Year 1710 ; and I find them to want a great deal 
of the Accuracy requir’d in fo nice a Point, as deter- 
mining the different Lengths of Degrees upon the Sur- 
face of the Earth. To prove my Alfertion, I beg that 
the Reader will examine the following Tables, whereby 
it appears, that if any thing certain can be deduc’d from 
the faidObfervations and Meafures, (either taken as they 
are, or reduc’d to the Level of the Sea, by the Rules 
given by Monf. CaJJini * ) it will be in Favour of Sir 
IJaac Newton's Figure of the Earth, rather than 
theirs. 
In the following Table, the firft Column gives the 
Names of Places ; thefecond,the Diflances from Tarts , 
according to the Meafures taken by the French Gentle- 
men • the third, the Latitudes obferv’d by the fame } 
the fourth, the Latitudes, fuch as the meafur’d Dillances 
will give them, fuppoling the Earth fpherical ^ the fifth, 
the Differences between thefe and the Latitudes obferv’d, 
exprefs’d in Seconds of a Degree, where when the La- 
titude computed, exceeds the Latitude obferv’d, the 
Letter N (North) {hews that Difference to be in Favour 
of Monf. CaJJini's Figure, and the contrary Difference 
mark’d by the Letter S (South) is in Favour of Sir 
Ifaac Newton's Figure.
