In this last form it was necessary to add the small constant to ^ 

 in order to obtain small and convenient numerical coefficients of the 

 constant 6 G. 



The following is an application of the last form to the example of 

 the moon's Right Ascension already given. From (13) we obtain, 

 putting 6) = 12,

With these values of the constants (20) gives the following re-
