114 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.
