In a previous paper the author (1) has shown the following theorem.

Theorem A. If each of H and K is a real-valued bounded function of subintervals of the number interval [a, b] and m is a real-valued non-decreasing function on [a} b] such that each of the integrals

exists, then the integral

exists.
