The excentricity of these curves is also independent of s"„ 

 and is tlienee the same for the whole family of orbits surroiind- 

 ing each one of the points Xj, L., and L.^. 



From the expressions for the derivatives its follows that 





da^ 



dh'' 



and hence we find that h is the major axis of the ellipse. 



The minor axis a is equal to ^^ as might be expected. 



By using the valnes of the derivatives, that are given in 

 Tab. I we get the following numerical values of the caracteristics 

 of the ellipses in X,, L^ and L^ for ^.i = 1, f< = 0.1 and u = 

 1 : 320000 resp.
