We observe that €,(/.) > 1 



as -^->x, since xo'^p. 



Now take the integral 



Jo X 



where 



xa' ^ a' {aj 



If we write 



(56) 



I ;, = x-^ 6, a^O, x'<d< {IjxY, 

 I ^' = _ a;-(i+^) e„ 5^0, x' <e,< (l/x)', 



we have, by the condition xa'Kp < o', 

 (51) bma^l + b, 



and, if a = b, Öj < 0; 



if a = l + b, Oi> 0. 



And we observe that, if b = 0, 



since a > IÇl/x). 



From (56), we liave x(t" ^ _ (i + h)a', 



and ( xp' ^ - ap (a > 0), 



I x(/ < p (a = 0). 



Hence
