the Two Obfervations, according to Mr. Bradlef^ 
Theory) was 57 Minutes 26 Seconds. Hence the 
Magnitude of a Degree, on the Earth, interfering 
the Polar Circle, was found to be greater than a mean 
Degree of France 377 Toifesj and to differ pooToifes 
from what it fhould have been, according to Mr. 
CaJJini’s Hypothefis: And if the Correction, accord- 
ing to Mr. Bradleys Theory, were omitted, the Dif- 
ference would have amounted to above a Thoufand 
Toifes: The Confequence of which, fay the . curious 
Obfervers, is, That the Earth is not only flatted to- 
wards the Poles, but that it is much more fo than 
Sir Ifaac Newton or Monfieur Huygens thought it. 
This unexpected Difference being fo very great, made 
them refolve upon a careful as well as new kind of 
Verification of the Whole. In the firft Place, they 
repeated their Aftronomical Obfervations Three fe- 
veral times, at Tornea and KittiSj with the fame 
inftrument, but on another Star, wz. cf Draconis : 
The Difference of Latitude between the Two Places 
was found to be the fame, within Three Seconds and 
an half, with the Firft. They then not only exa- 
mined the Truth of their Meridian Line, the ExaCt- 
nefs of the SeClor, in the different Divifions upon the 
Limb, chiefly in the Two Degrees imployed in ob- 
ferving a & S' Hraconis^ but fuppofed that, in their 
Trigonometrical Operations, they had erred- in 
each Triangle, by Twenty Seconds in each of the 
Two Angles, and Forty Seconds in the Third j and 
that all thefe Errors tended to diminifh the Length 
of the Arch 5 the Calculation, upon this Suppofition, 
gives but 44 Toifes for the greateft Error that could
