The periodic terms of (h.c.O), {h.s.l), {h.c.l), etc., are given in Chapter V, on 

 pages 86 and 87, and are to be taken withont any farther modification than the 

 multiplication of those due to the action of Neptune by the factor 0.863. The 

 constant, secular, and long period terms are 



b.c.O = +0".26 — 0".12T — O.OlUy; + OMGSx 

 (b.s.l) = —0 .227' — .05 T^ -\- 0.91ohy^ + 0.22Ux 

 (b.c.l) = +2 .477' + .127^^ + 0.2215>; — 0.975^z 

 (5.5.2) = —0 .06 — .01 7' 4- 0.0-l6^>7 + O.Oll^pc 

 (b.c.2) = —0 .01 +0.127' + 0.0115>7 — 0.046^x 



The values of hri and hx. to be used in these expressions are those the expressions 

 for which are given on page 97, and wliich are tabulated in the last two columns 

 of the table on page 184. 



The following tables are based on the elements and theory laid down in this 

 chapter.
