If the value of n determined in (336) be substituted for the 



4 . 



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

 o 



also be — 7.365. 



The coefficients and exponents involving n in the equa- 

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

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

 form, but they are no more simple than tho«e involving n. If 

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