But if X, is assumed to have the value a"'' then

and since q < 1/3 this is a posit ive power of a, whoie value accorainjly tenas tozeroasa-'o. 

 Thus the first term of (36) finally becomes nejlijiole in comparison with the secona, which 

 accorainjly repres'^nts the limiting form of K (a). Hence 



K (a) - Kj (a) - i^ a-^''' as a - o. 



When a is not inf initesimally smjll, K (a) will differ from its limitinj form. It has Coen 

 sstimated that the rslativ,. error involved is of the order a^.
