...constantly equal to three times the mean revolution of the second. And, the mean longitude of the Hrst, **minus three times that of the second, plus twice that of the third,** is always equal to two right angles. Hence, the first three satellites caunot be eclipsed at the same... | |

...motioti of the third, ia rigorously equal to thrice the mean motion of the second satellite. Stcond. **The mean longitude of the first satellite minus three...that of the second, plus twice that of the third,** is exactly eijual to a semi-circle or 180 degrees. By following out these laws, we find, 1st. When... | |

...are performed exactly in the same number of days. It has been found by La Place that " the epoch (or **mean longitude) of the first satellite, minus three times that of the second, plus** two times that of the third, is exactly equal to a semicircle, or 180 degrees." From this it follows,... | |

...which latter is about half that of the revolution of the third. Again, the mean longitude of the first, **minus three times that of the second, plus twice that of the third,** is always equal to 180° : hence it results, that when the first satellite is eclipsed, the other two... | |
