    • In Ref. 4, a two-dimensional resistor-capacitor network is employed to represent the interpenetrating pore and grain spaces. When random numbers are used to determine whether a given site will be occupied by a resistor or a capacitor, this model predicts that the dc conductivity vanishes at the conventional percolation threshold σ app σf(φ - φc )t. While the model described in Ref. 4 differs from those developed in Refs. 2, 3, and 5 in this repsect, it has in common with these models the fact that it relies on disorder to obtain a nontrivial power law.

    • The sedimentation process by which many sandstones are formed tends to favor distributions of particles that are roughly equal in size (Ref. 12). In this regard, the present algorithm could be contrasted with one in which the porosity is reduced by adding additional spheres with smaller and smaller radii to progressibely fill the pore space of the original packing. To achieve a comparable porosity range by this method, one would have to employ spheres whose radii vary over several orders of magnitude, and the final configuration would bear little resemblance to most naturally occurring porous materials.

    • With only three measurements, 0.032, 0.029, and 0.029, representing the percolation thresholds in the X, Y, and Z directions through a single finite sample, it is impossible to know the exact size of the statistical and systematic errors. The value given here seems to be a reasonable estimate, given the size of the sample and the consistency of the three measurements.
