And if one is not present at the nativity, but determines the rising image and the placement of the stars by appearance, he should immediately inquire the degree of the Hour-Marker. Investigate the conception. Let the degree of the Moon at the nativity be the Hour-Marker at the conception, and let the Hour-Marker at the nativity be the degree of the Moon at the conception.
When the Moon is rising at the Hour-Marker, the birth is intermediate of 273 days and 8 hours. If the Moon is above the horizon, the time will be less. If the Moon is below the horizon, the time will be more. Give one day for every 13.17 degrees of distance. When the Moon is unfavorably placed at the nativity, it will be necessary to subtract 27 days and 8 hours, or more proportionate to the bad influence. Thus make a scientific beginning, and fashion a forecast of the end.
