These conditions take the place of those given above relating to $n$. In fact, we might give conditions relating to the differential coefficients of $V$, similar to those given relating to the differential coefficients of $V_{q}$, instead of the conditions relating to $n$, for the validity of equations (360), (363)-(372). This would somewhat extend the application of the equations.
