    Sind die Asymptoten einer Curve vom Grade \(m\) \[ y-a_1 x+b_1=0, \ldots y-a_m x+b_m=0, \] und wird die Gleichung der Curve auf die Form gebracht \[ (y-a_1 x+b_1)\ldots (y-a_m x+b_m)+x^{m-2} \varphi_{m-2} \left( \frac yx,1 \right) +x^{m-3} \varphi_{m-3} \left( \frac yx, 1 \right)+\cdots =0, \] so sind die \(m\) cyklischen Perioden von \( \int ydx\) (vgl. F. d. M. V. 224, JFM 05.0224.04) die \(m\) Werthe von \(2\pi\sqrt{-1}\) \[ \frac {\varphi_{m-2} (a,1)}{ \varphi_m'(a,1)} \text{ für } a=a_1 \ldots a_m, \] wo \[ \varphi_m(y,x)=(y-a_1 x) \ldots (y-a_m x). \] Es wird nun gezeigt, dass diese Werthe Wurzeln einer Gleichung \(m^{\text{ten}}\) Grades sind, deren Coefficienten sich rational durch die Coefficienten der Glieder \(m^{\text{ter}}\), \(m-1^{\text{ter}}\) und \(m-2^{\text{ter}}\) Dimension der Gleichung der Curven ausdrücken lassen.
