The Potentials About a Point Electrode and Apparent Resistivity Curves for a Two-, Three-, and Four-Layer Earth was first published in 1956. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions.

This publication will be useful to geophysicists, geologists, and others engaged in exploration for minerals by electrical methods, and may be used in theoretical studies of electrical prospecting. It makes available for the first time a comprehensive collection of 2268 master resistivity curves for a two-, three-, and four-layer earth. All previous collections of curves for Wenner electrode configuration are included, so the user will not need to refer elsewhere to complete his set of working curves. In addition, the basic potential data used in computing the curves is given in tables. Auxiliary tables are provided to reduce the graphic integration procedures to simple arithmetic. The integral in question occurs widely in solutions to Laplace's equation.
