114 THE FUNCTION <. 



These conditions take the place of those given above relat- 

 ing to n. In fact, we might give conditions relating to the 

 differential coefficients of F", 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.
