We show that if E is an s-regular set in R-2 for which the triple integral
integral (E) integral (E) integral (E) (c)(x, y, z)(2s) dH(s) x dH(s) y dH(
s) z of the Menger curvature c is finite and if 0 < s <less than or equal t
o> 1/2, then H-s almost all of E can be covered with countably many C-1 cur
ves. We give an example to show that this is false for 1/2 < s<1.
