Prognostic Astronomy

1901. The scientific basis of the predictive art commonly called Astrology: to which is added a complete set of tables with emendations and new rules for the use of students. In publishing this short treatise on Primary Directions for the use of students of Prognostic Astronomy, I am conscious of invading systems already in repute, but I trust I have not done so without due cause. Most books on the subject, while aiming at mathematical precision, embody too much of what is already weighted with traditional error, and they fail entirely to convey a simple conception of what is being done and the reason for doing it.
