A Fourier analysis of the flow of electricity in a two-dimensional plate depends upon the solution of Laplace's equation in two dimensions. The problem considered in this paper is that of a rectangular plate, the potential being applied at two adjacent sides. The results of the experiment depended upon the finding of the equipotential lines. This was done by means of a dish forty centimeters wide and fifty centimeters long. Copper strips were placed on two adjacent sides. An ordinary storage battery was used as a source. The lines were then found by exploring the dish with the terminals of a D'Arsonval galvanometer. The lines of flow are then found to be at right angles to these equipotential lines.
