Abstract
We derive explicit expressions in the Schottky parametrization for the periods of the harmonic Beltrami differentials on an arbitrary Rieman n surface. Together with the N-point g-loop vertex for the reparametri zation ghost system this allows a direct calculation of any ghost corr ellator encountered in the picture changing operator approach to super string theory.
