If the value of h determined iu (336) be substituted for the 



value o ill Ritter's equation (30), of this paper, his result will

also be— 7.365. 



The coefficients and exponents involving n in the equa- 

 tions which precede, may now all be written in terms of k but 

 nothing is gained by doing so. They are very interesting in 

 form, but they are no more simple than those involving 7i. If 

 we replace n by the value 1.1, equations (10) to (14) become
