204 ON THE CONSTANT TERM, ETC. [25 



The coefficients of e* and y 4 were found independently, and from each 

 of these, by means of the relations proved above, was derived a value of 

 the coefficient of <?y. The perfect coincidence of these values supplied a 

 test of the correctness of the calculations. 



The terms of c and g which are required for this verification are the 

 following : 



c = 



64 



9= ...... +*(!i'+ 



I hope to lay the details of these calculations before the Society on 

 some future occasion.
