124 Approximate Values of the Radii of Curvature, S)C [Aug. 



1 - -0016122448 = -9983877, therefore c * " 9 f 3 ™ 



.= c x -2495969 = elliptic quadrant, or, 



Log. c = 7-3405713 



Log. -2495969 = 1.3972391 



Log. 5467772 fath = 6-7378104 



Hence we have the length of the elliptic quadrant : 



According to Col. Lamb ton = 5467494 "} 



By the table = 5467656 J. Fathoms. 



By example 10 = 5467772J 



If the length of a degree at the poles, as determined by 

 example 7, be correct, that is, 61048 fathoms, or 3-7 fathoms 

 greater than is shown in the table, it is evident that the sum of 

 the meridional degrees is a little too small. 



The Lengths of every Degree computed from the foregoing Data 

 from the Equator to the Pole.
