Rh of a function of $$a,\ldots h$$, which we may denote by $$a'$$. We have then which may be integrated by quadratures. In this case we may say that the principle of conservation of extension-in-phase has supplied the 'multiplier' for the integration of the equation

The system of arbitrary constants $$a', b, \ldots h$$ has evidently the same properties which were noticed in regard to the system $$a, b', \ldots h$$.
