Using a special form of spanning surface for a knot, we give a formula for the coefficient of the z^2-term of the Alexander-Conway polynomial in terms of the sum of determinants of the blocks of 2x2 submatrices of the Seifert matrix, from which the topological meaning of the coefficient is revealed.
