We see at once that : 



n u =GI, and r is positive in Table (i) = 

 n u ' = d z , and r is negative in Table (ii) = 

 n v a a , and r is negative in Table (iii) = 

 n v ' = 64, and r is positive in Table (iv) = 



+ '5189, 



-5189, 



'5189, 

 + '5189.

Accordingly : 



*r f a 9 c l 4 2\ 



w 8< = N - - - . + - . 



There are thus two tables to be worked for r positive (i.e. (i) and (iv)) and two 

 tables for r negative (i.e. (ii) and (iii)). 



Accordingly, in only one case is the n u or n v equal to d, namely n M ' = rfj. For 

 the other cases we require to use the formulae given in equations (iv). 



Further, we shall need to use special interpolation formulae for three of the 

 cases, as we are at the edges of our tables for d/N. We may arrange our work as 

 shown on the following page, where a, 0, 7, 7 bis, and 8 refer to the formulae on 

 pp. xvii xxi above.
