Die Arbeit ist im wesentlichen ein Abdruck einer früheren aus dem Jahre 1877 (vgl. F. d. M. IX. 795, JFM 09.0795.01). Es mag deshalb hier nur bemerkt werden, dass das an sich sinnreiche, aber wenig strenge Verfahren des Herrn Verfassers zur Integration der Differentialgleichung \[ \frac {d^2x}{dt^2} + x.X = 0, \] \[ X = a_0 + a_1\cos t + a_2\cos 2t + \cdots, \] seitdem durch strenge Entwickelungen ersetzt worden ist (vgl. F. d. M. 1883. XV. 980-981, JFM 15.0980.03).
