 where Qi and ^, are the ordinary elliptic values of the radius- vector 

 and the equation of the centre. We have, in astronomical units: 

 log a, = 7-450 13884 - 10 

 log a, - 7-651 82910 — 10 

 log a, = 7-8h4: 62721 —10

 From the above values of e, we tind : 

 Q^= 1.000 00873 



The inequalities in longitude are expressed in degrees. The angle t is 

 counted from the opposition of II and 111 on 1899 June 28, ll''47"^35« 

 Greenwich mean time. (See "Outlines", these Proceedings Vol. XX.
