...mean longitudes themselves are subject to a law equally remarkable : this is, that the mean longitude of the first satellite minus three times that of the second, plus twice that of the third, is always equal to a semicircumference, or 180°. The relation applies equally to the mean longitudes,... | |

...to exist between the mean longitudes of the three first satellites. It is this ; the mean longitude of the first Satellite minus three times that of the second plus twice that of the third is equal to 1 80° ; in symbols, then, (nt + e) - 3 (n' t + O + 2 («" t + «") = 180°, consequently,... | |

Another singularity in this secondary system, is, that the mean longitude of the first satellite minus three times that of the second, plus twice that of the third, never differs from two right angles, but by a quantity almost insensible.
