This rule is one of the strangest I have been able to find. It is very simple, although it entails work to project correctly. We use the geocentric longitude of Sun at any important top or bottom. To this longitude we add each time the value 126°30’. When the addition has been made and the exact place located in the Zodiac, i.e. the degrees and minutes and the right sign belonging to them, we look when Mercury is going to pass this point. Hold fast that day! The movement that developed previously at the Sun’s place will come off in the same direction at the Mercury place. Thus, Mercury imitates the Sun’s effect.
[...] This law I dug out of the Hebrew Talmud. What the Sun does, Mercury does the same 126°30’ later. We only apply this rule from extreme tops and extreme bottoms. The effect is felt only several months later and not a few weeks later.
[...] There is a small matter to discuss yet, at least to draw your attention to. We know that Mercury moves at times retrograde. Should that measurement coming from the Sun reach Mercury at the time it moves retrograde, we have first a place over which it does move direct and only after that does Mercury retrograde and pass over the same Sun projection of 126°30’ and again after it turns direct it must pass the same spot again.
