title: Bosi's method for solving Laplace's equation.
abstract: Conformal mapping is used to obtain an implicit solution for a slightly specialized version of a planar electrostatic mirror for which Bosi claims to have obtained an exact solution by means of a Taylor series in the ratio of two dimensions. It is shown that the intervention of logarithmic terms invalidates Bosi's series after the first-order term. Comparison of Bosi's series for cylindrical and spherical mirrors with the exact expansion for an analogous planar problem suggests that in these cases not even the first-order terms are valid.
