13. From these data the coefficients 7t of the different terms of the perturb- 

 ative function, their differential coefficients, and the perturbations of the co- 

 ordinates, are found to be as in the following table. The N's, it will be seen, are 

 grouped according to the values of their constant parts, /of -j-jb. 



h, its differential coefficients, L, W, and E, are given in units of the third J>/<K;> 

 of decimals, to avoid writing zeros. The logarithms are reduced to the common 

 base, 10, .and are expressed in units of the seventh place.
