the several stations Iving near the direction of the meridian with 

 a good repeating circle, or other astronomical instrument of great 

 accuracy, ujion circumpolar stars above and below the pole ? as 

 such observations would remove all doubt upon the measure of 

 the celestial arcs, and might be soon made by any zealous and 

 active observer.*

* If there should be found at the station at Arbury Hill an error in the 

 measure of the celestial arc amounting to 3 or 4 seconds of a degree, which 

 from the smallness of the quantity may have crept into the account, and also 

 if the angle niio upon the whole arc is found by accurate computation to 

 amount to about S", the whole will agree with an elliptical meridian of 

 229-2.30 very nearly, and also agree with deductions derived from measure- 

 ments upon other parts of the earth.
