The Type of a Riemann Surface,into . which correspond one-to-one to the branch points of . in such a way that one elementary region with 2m sides is associated with a branch point of order . — 1. Corresponding in the complex to the sheets which are unramified over the base points are two-sided figures (double 1ine segments).
