The numerical values in the table were computed by me 

 and checked by Mr. H. B. Shaw, so that it is believed no 

 error exists in them. 



In computing the values of X given by (14) it was found 

 that the results could be found correctly to the last figure 

 given, for N = i, 2, by taking only the first term of the 

 parenthesis and neglecting the others; for N ^3 to 11 

 inclusive, two terms are needed and for N = 12, 13, 14, 

 15, only three terms are required. For the values of Y, 

 two terms of the parenthesis in (15) were used up to N = 9 

 inclusive; for greater values of N three terms only are 

 required. 



^ six figure table of logarithms was used except for the 

 larger values, where a seven place table proved desirable.
