i93°-l QUASI *-FOLD TRANSITIVITY 857 be set up by combining the integral around the boundary with integrals over specified curves interior to the region, or by using area integrals together with line integrals, or by admitting values of the error at isolated points in the expression to be minimized.It is clear that this type of generalization would lead ultimately to the consideration of a Stieltjes integral, though the precise degree of generality that would be practicable remains to be ascertained.
