suitable integral equations, so that all the conditions of the problem should be 
satisfied. This, in itself, would not amount to more than a formulation of the 
general problem in different terms and would not advance its practical solution, 
unless possibly such a form of statement should lead to improved methods of 
approximation for the equivalent distribution.
