On the figure of the EARTH. 319 



Hence, if the arch AL exceed the arch LB, BC is 

 greater than AC ; but, if AD reprefent the axis of the 

 earth, and BE the equatorial diameter, it is found by ac- 

 tual meafurement, that each degree of the arch AL is 

 greater than a degree of the arch BL, and confequently 

 the whole arch AL is greater than the whole arch BL, 

 and therefore BC is greater than AC. C^E. D.
