Doolittle, Russell Carter (1940) The theory, construction, and field use of a direct current, potentiometer for measuring earth resistivity. Master's thesis, California Institute of Technology. http://resolver.caltech.edu/CaltechTHESIS:03122010-083823737
The fundamental theory underlying direct current methods of measuring "apparent" earth resistivity and of interpreting these field measurements to obtain the actual resistivities of the parts of a composite earth is extensively reviewed. The three main types of apparatus used in making the field measurements, the Gish-Rooney, "Megger", and "porous pot" instruments, are briefly outlined. Considerations involved in making a general design for a "porous pot" outfit are briefly discussed, and a detailed description of the apparatus used by the writer is given. Field data obtained with this apparatus is interpreted by the several methods discussed in the literature.
