 Now the sun attracts the moon, and disturbs it as he would the path of the mountain we have just supposed, and the effect is the same — viz., the intersections of the moon's orbit with the ecliptic travel backward, completing a revolution in about 18...

...make a complete revolution in nineteen years. The consequence is that for nearly half that interval the moon's orbit is inclined to the ecliptic in the same way as the earth's Equator, though not to the same degree ; and during nearly the other half of the time the moon's orbit is inclined... | |
