y points, Fig. 3, exhibit-ing the synodic orbit of the minor planet; where, in explana-tion, itis necessary only to say that when Jupiter is severallyat ■/ and ./ the planet is severally at / and /. On com-parison of Figs. 2 and o, it will be noticed that, in thelatter, 1 lying between / and ./… … Our second example will be the minor planet of theHecuba type, where I; = 2 and k = 1. Then, with simi-lar conditions and notation as in the first example, theterms of the perturbative function, made secular by thecommensurability of the mean motions, are R = (H)2x+(12)Y+(13)Y2x + (42)Yx2+(89)YaX +…
